In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: ?It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge.? This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, com- mencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions to History and Technology Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Museum Conservation Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology In these series, the Institution publishes small papers and full-scale monographs that report on the research and collections of its various museums and bureaus. The Smithsonian Contributions Series are distributed via mailing lists to libraries, universities, and similar institu- tions throughout the world. Manuscripts submitted for series publication are received by the Smithsonian Institution Scholarly Press from authors with direct affilia- tion with the various Smithsonian museums or bureaus and are subject to peer review and review for compliance with manuscript preparation guidelines. General requirements for manuscript preparation are on the inside back cover of printed volumes.

David Clarke introDuction V. A. Funk and C. L. Kelloff The Biological DiversiTy of The guiana shielD Program The Biological Diversity of the Guiana Shield (BDG) program is a field- oriented program of the Smithsonian Institution?s (SI) National Museum of Natural History. The goal of the BDG is to study, document, and preserve the biological diversity of the Guiana Shield (Figure 1), which includes Guyana, Suriname, French Guiana, the Venezuelan states of Amazonas, Bol?var, and Delta Ama?uro, and parts of southern Colombia and northern Brazil. The BDG program has been operating since 1983. Originally confined to botany, it now covers all aspects of biodiversity. Data gathering and analyses of diversity are focused on the natural unit of the Guiana Shield (Escudo de Guayana in Span- ish) rather than on political units. The Guiana Shield is a biologically diverse area defined by a distinct, an- cient geologic formation that is roughly bounded by the Atlantic Ocean to the east, the Orinoco River to the north and west, the R?o Negro, a major tributary of the Amazon River, to the southwest, and the Amazon River to the south (Gibbs and Barron, 1993). The Orinoco and R?o Negro Rivers are connected by the substantial Rio Casiquiare, making much of this geologic area an island. The Guiana Shield contains many isolated steep- sided mountains of sandstone (tepuis) and granite (inselbergs), which, together with an assortment of habi- tats that includes tropical savannas, lowland and montane forests, and montane scrub, help to account for the high diversity and endemicity of the flora and fauna (Berry et al., 1995). Unlike many other tropical regions, 60%?70% of the natural habitat of the Guiana Shield remains pristine. In the three Guianas (Guyana, Suriname, and French Guiana) in particular, because national govern- ments own most of the land and the population is concentrated along the coast Carol L.

Manuscript re- ceived and accepted 26 May 2011. 2 ? S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y and major rivers, destructive development of the interior has been kept to a minimum. Conservation efforts vary within the region. In parts of Suriname and the Venezuelan Guayana, large tracts of extremely interesting forest and their accompanying biota have already been designated for conservation. In contrast, in Guyana the process of establishing protected areas is in its early stages. Many natural areas in both Guyana and the Venezuelan Guayana are designated as concessions and are therefore seriously threatened by re- source extraction activities as practiced by multinational logging and mining companies. Each country has suffered severe degradation in certain areas due to gold miners, both legal and illegal, from inside and outside of the coun- try. It is important that we gain an understanding of the flora and fauna of the Guiana Shield to make informed decisions concerning critical areas that have high priority for conservation and to guide the collection of data from areas that might ultimately become degraded. In addition, because this region has been long neglected by biologists, it is often an area of ?insufficient information? for analy- ses of many biological groups. The BDG program aims to fill these gaps by providing specimens and data to address biodiversity questions about many groups of organisms and to assist a variety of research and conservation proj- ects. This new information is now being used to produce checklists and vegetation maps, and in floristic and faunis- tic studies. In addition, the BDG program is exploring uses of these data that will lead to a synthesis of information addressing a broader understanding of biodiversity issues (Funk and Richardson, 2002; Kelloff, 2003; Kelloff and Funk, 2004; Funk et al., 2005; Hollowell and Reynolds, 2005; Hollowell, 2009; Vari et al., 2009). Prior to the BDG?s work Guyana was poorly known biologically, with sparse documentation of the com- position and distribution of its biota. After 24 years of figure 1. The Guiana Shield. Boundaries are adapted from Gibbs and Barron (1993). The dashed boundary includes isolated outliers of similar geologic composition that are sometimes included in the Shield. N U M B E R 9 7 ? 3 collecting the BDG program has produced many works important to understanding Guyana?s biological diversity and to assisting Guyana with conservation efforts. The BDG program has published a vegetation map of Guyana (Huber et al., 1995), as well as plant checklists for the Guianas (Boggan et al., 1997), the Guiana Shield (Hollowell et al., 2001; Funk et al. 2007), the Iwokrama area (Clarke et al., 2001), and Kaieteur National Park (Kelloff and Funk, 1998). The program has also published the Field Checklist of the Birds of Guyana (Braun et al., 2000, 2007). Data from the BDG program have been used in many publications. A complete list can be found on the program?s website at http://botany.si.edu/bdg/index.htm; most are available as PDFs (Engstrom and Lim, 2001? present; Reynolds et al., 2001?present; Hollowell and Reynolds, 2005; Funk et al., 2007; Vari et al. 2009). The Checklist of the Terrestrial Vertebrates of the Guiana Shield was published in 2005 (Hollowell and Reynolds, 2005). The checklist contains all known non- fish vertebrates (and their distribution on the Shield) and includes chapters on birds, mammals, amphibians, and reptiles by authors from Canada, Venezuela, Brazil, and the USA. The Checklist of the Fishes of the Guiana Shield (Vari et al., 2009) was published as a companion to the terrestrial vertebrate checklist. These two works represent the most current knowledge of the diversity and distribu- tion of vertebrates of the Guiana Shield. The checklist of fishes known from the freshwater systems of the Guiana Shield includes 1,173 species, representing approximately 23% of the freshwater fish species from the vast expanse between southern South America and the southern border of Mexico (Reis et al., 2003). The checklist also accounts for more than 4% of the 28,400 fish species recently esti- mated to be present in all marine and freshwater systems worldwide (Nelson, 2006; Funk and Kelloff, 2009). The Checklist of the Plants of the Guiana Shield (Funk et al., 2007) covers all vascular plants known to occur in the Guiana Shield region of northeastern South America and includes a forward by Dr. Peter H. Raven, President Emeritus at the Missouri Botanical Garden. This checklist, together with the publications on terrestrial vertebrates and freshwater fishes, represents a new research and con- servation resource that highlights three critical facets of taxonomic work: expeditions, collections, and research. The BDG fulfills the mission of the Smithsonian In- stitution?the increase and diffusion of knowledge?by gathering and distributing new information. The program encourages production of floras and faunas of poorly known areas, participates in training students and professionals from the host countries, supplies data for identification and preservation of biologically diverse areas, and supports interdisciplinary research. Although the program operates out of the Smithsonian Institution, it depends on the col- laboration of specialists worldwide and a steady source of funding to accomplish its goals. Currently, more than 800 scientists and collaborators have produced more than 500 publications (the BDG website lists collaborators and other information: http://botany.si.edu/bdg/index.html). From 1986 to 2000 the BDG program maintained either a full- time or a part- time resident collector in Guy- ana. Since 2000 regular expeditions are sent to various places across the Shield. Most of the expeditions collect plants but some have collected butterflies and moths, ants, and birds. Botanical specimens collected through the pro- gram are distributed to a network of experts for identi- fication. Specimens from all expeditions are deposited at the Centre for the Study of Biological Diversity (CSBD) at the University of Guyana in Georgetown, as well as at the Smithsonian Institution in Washington and at other museums worldwide. At the time of publication the BDG program has produced approximately 55,000 collection numbers, representing more than 263,000 individual specimens. The CSBD herbarium in Georgetown currently holds over 45,000 mounted plant specimens and the zoo- logical collection has over 10,000 vertebrate specimens and 22,000 insect specimens h. DaviD clarke BioskeTch H. David Clarke was the eighth and last full- time resident plant collector (1995?1997) to participate in the BDG program (Figure 2). After his time in Guyana, Clarke spent three years at the Smithsonian Institution as a postdoctoral fellow, then accepted a position at the Uni- versity of North Carolina at Asheville (UNCA). As associ- ate professor in the department of biology, Clarke teaches introductory and advanced botany courses in plant sys- tematics, field botany, plant anatomy and morphology, economic botany, tropical biology, and the humanities. Until recently much of Clarke?s time, when not at UNCA, was spent in the rainforests of Guyana, where he was often accompanied by one or more students involved in undergraduate research. Between 1994 and 2004 Clarke spent more than 20 months in Guyana in the field and collected nearly 12,300 plant numbers. These specimens were processed first at the CSBD in Georgetown and then by the U.S. National Herbarium at the Smithsonian Insti- tution. At the time of publication, just over 78% of these collections have been identified to species. The determina- tions show that Clarke collected more than 3,015 taxa in 4 ? S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y 1,060 genera. Copies of his field notebooks and mounted vouchers for these collections are now in the Guyana Na- tional Herbarium, housed at the CSBD, and at the U.S. National Herbarium in Washington. Partial sets of the col- lections are housed at several other institutions. As a resident botanist Clarke played an informal but important role in outreach to the general population in Guyana. The Smithsonian collectors lived in George- town neighborhoods and endured the same irregularities in services as their fellow Georgetown residents. Clarke customarily traveled about the city on foot or by bicycle and minibus, shopped in the street markets and bakeries, and commuted to the university in public minivans. After conducting several extended field trips, Clarke presented public talks on plant diversity and expeditions in down- town Georgetown and at the University of Guyana high- lighting Guyana?s amazing flora and fauna on the tepuis; these talks generally drew large audiences. The BDG?s resident plant collector also provided an ac- tive link between the Smithsonian?s research efforts and the programs of other institutions. For example, Clarke main- tained friendships and frequently discussed fieldwork with researchers such as John Wurdack, Larry Skog, and other curators from the Smithsonian, Scott Mori of the New York Botanical Garden, and zoologists from the Royal On- tario Museum. The resident botanists thus played a greater role in the Smithsonian mission than merely planning field expeditions and collecting plant specimens. They were ac- tive, dedicated, and, not insignificantly, apolitical outreach persons who represented the amiable, pro- conservation and pro- education interests of the United States scientific community. Each resident collector was the key person in the country who kept the collaborative relationship ac- tive over the months and years. In addition, many of the BDG?s collectors, Clarke included, used their experience in Guyana to gain hands- on knowledge of tropical biol- ogy and to build on it to enhance their careers as profes- sional botanists. During Clarke?s stay in Guyana, he was accompanied in the field by several Guyanese biology students, foresters, and botanists. From the University of Guyana Herbarium, co- collectors included Tsitsi McPher- son, Keith David, Diana Gittens, and Christopher Chin; these individuals also participated in some of the collect- ing trips with other Smithsonian botanists and zoologists. With this experience they were able to develop their own research interests and went on to pursue graduate studies. Many other Guyanese, including Amerindians (Claudius Perry and Romeo Williams) and other residents of interior towns and settlements, participated in collecting trips with Clarke. The collecting teams normally included two to six local men who served as guides, shared the backpacking of supplies and specimens, and set up camps in remote areas. These hired workers were paid by the day for the extent of the trip, with food provided from the stocks the col- lector brought from Georgetown. Strong friendships often developed between the resident botanist and the Guyanese members of the team as they shared the challenges of travel and botanical fieldwork under difficult circumstances and in inclement weather. Among the Guyanese members of teams who also assisted Clarke with collecting, as recorded on the specimen labels, were Calvin Bernard and Cynthia Watson from the University of Guyana. Scientists from several countries sometimes partici- pated in field trips organized by Clarke. For instance, Clarke conducted field expeditions with American bota- nists, lichenologists, and graduate students, including Scott Mori and Scott Heald (New York Botanical Garden), Pe- dro Acevedo and Paula DePriest (Smithsonian Institution), Erin Tripp, Josh Kelly, and Stephen Stern (University of North Carolina at Ashville), and international botanists figure 2.

Clarke?s first collecting trip in Guyana was to Iwokrama International Centre for Rainforest Conservation and De- velopment to fulfill a contract between the Smithsonian Institution and the Iwokrama Rainforest Programme to document the plant diversity of the reserve (Clarke et al., 2001). An important practice of the BDG program was to have resident collectors overlap both in the field and in Georgetown. Clarke did not have the advantage of an overlap with previous resident collectors, but the infra- structure was well established and the first expedition into Iwokrama allowed him to become familiar with field work in Guyana. After his term as a collector with BDG, Clarke made yearly expeditions in Guyana, bringing students to collect plants in the higher elevations of the Pakaraima Mountains. These students were Erin Tripp and Josh Kelly to Mount Ayanganna (2001); Erin Tripp, Josh Kelly, Diana Gittens, and Stephen Stern to Mount Wokomung (2003); Jay Rhodes to the Central Suriname Nature Reserve in Su- riname (2004); and Erin Tripp, Stephen Stern, and Diana Gittens to Mount Maringma (2004). In addition to his fieldwork on the Guiana Shield, Clarke?s experience included work in Central America, Mexico, and the Caribbean, producing collections from Mexico, Costa Rica, Puerto Rico, and the Dominican Re- public. To advance his fieldwork Clarke continues to seek funding and in recent years has received grants from the Smithsonian Institution, Conservation International, the National Geographic Society, and Geo Magazine. Al- though Clarke still participates in field trips to Guyana, his research interests in biodiversity studies now extend beyond the flora of the Guiana Shield. His latest research project is the classification and evolution of Acacia (Fa- baceae: Mimosoideae) and related tropical legumes. He is currently examining the evolution and biogeography of Acacia based on molecular sequence data. Clarke has pub- lished in several leading journals, including Proceedings of the Academy of Natural Sciences, Systematic Botany, and American Journal of Botany, the popular publication Or- chid Digest, and several monographs. His publications in- clude articles about using checklists and collections data to investigate plant diversity (Clarke and Funk, 2000, 2005; Clarke et al., 2001) and the analysis of the plant diversity of the Iwokrama forest, Guyana (Clarke and Funk, 1998), and several articles on Acacia (Ebinger et al., 2000; Clarke et al., 1989, 2000). formaT of collecTion informaTion More than 150 taxonomic specialists and other bo- tanical professionals have participated in identifying plants collected by Clarke. Now that more than 78% of these collections have been identified, this publication makes the results of his fieldwork widely available in print and electronically to the botanical and conservation communi- ties. This publication also serves as a resource for many herbaria that have received duplicates of these collections because, as with such endeavors, specialists may revise the determinations of specimens and data errors are discovered and corrected over time. These data will be periodically updated on the ?Expeditions? page on the BDG website (http://botany.si.edu/bdg/index.html). The BDG website also provides information about expeditions conducted by the program, including trip reports, lists of collections, im- ages showing different aspects of field work, and collection localities (using Google Maps as a mapping application). This publication is divided into four parts. Part I con- tains narratives prepared by Clarke about the localities, habitats, people, and events of the collecting trips. Maps are included that show each collecting trip, along with some of the place names mentioned in the trip narratives. The maps were produced using ArcMap 8 (ESRI, 2002) with basemap coverages produced through the BDG?s collaboration with the CSBD at the University of Guy- ana. Part II is a detailed account of the localities where Clarke made his collections for the BDG program; these are listed chronologically and grouped by trip. The range of collection numbers for each trip is indicated, as are the dates of the trip. Within each trip, specific localities, as provided by the collector, are listed with their collection number ranges, the date for those collections, latitude and longitude coordinates, elevation ranges in meters, habitat descriptions, and co- collectors. Latitude and longitude are given in degree (?), minute (?), and second (?) format and were taken using a Global Positioning System (GPS). Part III lists Clarke?s collections in numerical order. Each collection number is followed by the determined plant family, the plant name and any infraspecific names that have been provided, and authors of the name. The plant name information may be checked against the synonymy provided in the Checklist of the Plants of the Guiana Shield (Funk et al., 2007) available online at http://botany.si.edu/ bdg/plants.html. The authors of plant names conform to standard abbreviations (Brummitt and Powell, 1992). Part IV lists collections by determined name sorted by division, family, genus, and specific epithets, followed by collection numbers for each name. Specimens not 6 ? S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y determined to genus are the first listed for each family, and specimens not determined to species are the first listed for each genus. This section is provided to facilitate the location of specimens of interest to specialists. In addition, there are color plates located at the end of the book. The first set of all Clarke collections has been distrib- uted to the Guyana National Herbarium at CSBD and a second sheet has been deposited at Smithsonian?s U.S. Na- tional Herbarium in Washington. Additional duplicates have been distributed to herbaria in the Americas and Europe as part of ongoing exchange programs. Anyone requiring additional information about these specimens or about the specialists and other individuals who partici- pated in determination of specimens may contact the BDG Program at the U.S. National Herbarium, Botany, MRC 166, P.O. Box 37012, Smithsonian Institution, Washing- ton DC, 20013- 7012 USA. This is the fourth publication by the BDG detailing the collections of the program?s resident plant collectors. The first publication covered the collections of John J. Pipoly from 1987 to 1988 (Hollowell et al., 2000), the second covered the collections of Lynn J. Gillespie from 1989 to 1991 (Hollowell et al., 2003), and the third covered the collections of Tim McDowell from 1990?1991 ( Hollowell et al., 2004). As identification of specimens collected by other BDG botanists approaches at least 75%?80% com- pletion additional publications will be issued in this series. This is publication number 160 in the Smithsonian?s Bio- logical Diversity of the Guiana Shield Program publication series. references Berry, P. E., B. K. Holst, and K. Yatskievych, eds. 1995.

Among these people are Tom Hollowell, Margaret and Malcolm Chan- A- Sue, Phil- lip daSilva, Michael Tamessar, and Marilyn Hansel. We also thank Erin Tripp and Karen Redden for suggestions on the manuscript. The multitude of specialists, both past and present, who have helped in the determination of H. David Clarke?s specimens from Guyana, are acknowledged below. Expeditions in Guyana are not possible without the assistance of many local counterparts and Amerin- dians. We thank the many individuals who participated in Clarke?s expeditions: S. Adkins, C. Bernard, C. Chin, J. Clarke, K. David, D. Gittens, S. Grose, S. Heald, B. Hoff- man, T. Hollowell, K.

Hollowell, 2005 Guianas (For detailed collection localities and collection numbers, see Part II: Collecting Localities) During an expedition the goal is to document the botanical diversity of a georeferenced collecting locality chosen by the expedition members. In each locality attempts are made to collect plants of as many different growth habits and types as possible, ranging from submerged aquatic vegetation to emergent aquatics and rheophytic vegetation, seasonally flooded forest, herbs, vines, lia- nas, and herbaceous plants growing at the river?s edge, and, in terra firme forest, understory herbs and shrubs, midstory trees and palms, canopy trees and lianas, epiphytes, and canopy- emergent trees. Members of Clarke?s expeditions were able to climb trees up to about 80 cm in diameter and to collect in the canopy by using tree- climbing spikes and extendible aluminum clipper poles. Climb- ing trees takes a great deal of time but these collections of epiphytes, lianas, and large canopy trees are the most valuable because they are the most poorly known and least well represented in herbaria. The difficulties of identifying material from neotropical forests necessitates that plants for the most part be fertile (flowering or fruiting). A pressed, dried herbarium specimen must be made so that identification can be made in the herbarium with full use of reference collections, botanical literature, and dis- secting microscopes. The herbarium specimens that result constitute a record of the expedition that, if properly maintained, will remain in good condition for hundreds of years. The trip narratives that follow are extracts from the expedi- tion reports of H. David Clarke. triP 1: iWoKrama rainforeSt reSer Ve 17 sePTemBer To 9 ocToBer 1995 (maP 1) The purpose of this collecting expedition was to continue to document the flora of the Iwokrama Rainforest Reserve and to produce a checklist to fulfill a contract between the Smithsonian Institution and the Iwokrama program. The work was intended to extend and complement the work done by previous col- lectors: Bruce Hoffman, Toby Pennington, and Patrice Mutchnick. Collecting I. Expedition Narratives and Maps 2 2 ? S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y MAP 1. Collecting localities of H. D. Clarke, Trips 1?3. N U M B E R 9 7 ? 2 3 efforts were concentrated along rivers and machete- cut transect lines with the goal of sampling across a number of the different land systems described in the Iwokrama Phase 1 report. The collecting was expected to help to achieve a refined understanding of these land systems and the veg- etation they support. During the expedition, Iwokrama personnel abandoned mapping the reserve on the basis of Iwokrama Phase 1 land systems in favor of a map de- lineating more detailed vegetation types (a la Fanshawe). No matter which system is used, the collecting serves to validate maps constructed largely from aerial photographs and knowledge of soils, topography, and geology. We arrived in Annai by twin- engine Islander aircraft flown by Malcolm Chan- A- Sue and were met at the air- strip by Fred Allicock, the Iwokrama site manager, and a crew of Macushi workers from Surama. We traveled to Kurupukari field station by Land Rover and on to the Turtle Mountain transect on the Essequibo River by boat. We began collecting along the transect with the help of one guide (Daniel Allicock), the boat captain, and two workers. The transect began in alluvial Mora forest and moved up into upland forest on brown sands. We also col- lected along the river on the way back to the field station and along the entrance road to the field station from the Kurupukari?Annai Road. On 20 September we made a day trip to collect along the A?B transect, which begins at the Kurupukari?Annai Road and heads in an easterly direction. The area was dominated by Mora forest and mixed forest on white sand. The next day we made another day trip to collect along the C?D transect, which begins at the Kurupukari? Annai road and heads in a nearly westerly direction 5 km to the Burro- Burro River and then extends another 9 km beyond the river. Collections were made between the road and the river in Rapatea swamp forest and in mixed forest and wallaba (Eperua spp.) forest on white sands. During our second day trip to the A?B transect on 22 September we were filmed by a Canadian film crew. The expedition next collected along the first 4 km of the Kuratoka Rapids transect, which begins at the Esse- quibo River and heads 9 km in a westerly direction to very nearly meet the A?B transect. The forest was relatively dis- turbed (reportedly by fire) and contained a good deal of secondary growth species not common elsewhere (Acacia, Triplaris, etc.). After a day of plant processing and preparation, we traveled by boat (a very inefficient 25 hp motor that used 25 gallons of gas on this trip) from Kurupukari to the camp at the head of Post Arinda Inlet on the Esse- quibo River. We began collecting along a 4 km transect that started at Post Arinda Inlet and ended at Burro- Burro River above its confluence with the Siparuni River. This transect included varied topography with Mora forest, Mauritia swamp forest, and upland forest on a series of low ridges that paralleled the two rivers. Labaria (Bo- throps atrox) and spider- (Ateles sp.) and howler- monkeys (Alouatta spp.) were seen along the transect, and tapirs were seen near camp at night. After finishing collecting along the Post Arinda Inlet transect with two workers, we were met by our guide and boat captain at the end of the transect on the Burro- Burro River. We traveled by boat up the Burro- Burro River to camp at the intersection of the C?D transect with the river. A jaguar was spotted swimming across the river. Collec- tions were made along a 9 km extension of the C?D tran- sect on the northern side of the Burro- Burro River. Most of the length of this transect was mixed forest on white sand, but the transect ended in a Humiria (muri) savanna with a low (5 m) canopy, presumably created by edaphic conditions leading to poor drainage in the wet season. We also collected along the Burro- Burro River, between the C?D transect above Dunari Rapids and the confluence with the Siparuni River before our return to Kurupukari to process plants. The expedition made some last riparian collections along the Essequibo River north of Kurupukari. We then traveled by boat with a 25 hp motor with the crew (guide, boat captain, two workers) to camp at the head of Ak- romukru transect. As we collected along the 5 km long transect we saw several red brocket deer. The transect was dominated mostly by mixed forest on white sands, but nu- merous small canopy gaps added diversity (Ochroma, e.g.). Caryocar nuciferum L. is common near the Essequibo. Continuing along the Essequibo River at the southern boundary of the reserve, we collected along 5 km of the Ladysmith Creek transect. The Mora excelsa Benth. forest near the river changes to Chlorocardium with Mora gon- grijppii (Kleinhoonte) Sandwith forest away from the river. The striking orange bird, Cock of the Rock (Rupicola rupic- ola), was seen along this transect. After collecting along the Essequibo between Ladysmith Creek and Pisham Pisham Rapids, we collected along the 5 km long Pisham Pisham transect. Mora forest near the river gives way abruptly to hill forest as the transect crosses a ridge that slopes gently on the side facing the river and drops abruptly on the side away from the river. Extensive rock outcroppings on this ridge provide habitat for terrestrial bromeliads (Ananas) and epilithic ferns. Further riparian collections between Pisham Pisham Rapids and Gold Falls found rheophytic Mourera fluviatilis Aubl. blooming in the rapids. 2 4 ? S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y Finally, we returned to Kurupukari to process plants before our return to Georgetown in the Skyvan transport aircraft. triP 2: iWoKrama rainforeSt reSer Ve 4 novemBer 1995 To 2 DecemBer 1995 (maP 1) This was the second trip I made to the Iwokrama Rainforest Reserve as part of an ongoing effort to pro- duce a checklist of its flora to fulfill an agreement between the management of the reserve and the Smithsonian In- stitution. The previous trip, made in September and Oc- tober 1995, concentrated on collecting along transects starting along the Kurupukari?Annai road and along the Essequibo and Burro- Burro Rivers. Collecting on this trip concentrated on areas not visited earlier, including the Pakutau Hills along the Siparuni River, the Iwokrama Mountains, and a new transect along the Burro- Burro River. A new vegetation map of the reserve made by Ivan Anderson was used to help direct collecting efforts and, in turn, it was hoped that information from this trip could help to refine the map by providing information about previously unvisited areas. Throughout this trip, Bruce Hoffman was an accompanying botanist, recording data in 0.1 ha plots in an effort to assess a- and b- levels of plant species diversity. Bruce Hoffman and I flew from Georgetown to An- nai where we were met by Fred Allicock and workers. We moved to the field station at Kurupukari and made prepa- rations for a week- long trip to the Siparuni River. On 6 November we traveled by boat with a 40 hp en- gine to Pakutau Falls on the Siparuni River. The Siparuni River is occupied by several gold mining dredge opera- tions between Pakutau Falls and its confluence with the Essequibo River. It is otherwise uninhabited and undis- turbed, aside from where it is crossed by the old Mahdia? Sandstone road, which is now very overgrown. Malaria is common in this area. There the geology is characterized by doleritic intrusions that are slightly more basic than the granites that characterize most of the rest of the reserve. Although both Bruce Hoffman and Patrice Mutchnick have collected in this area previously, further collections were made in an effort to assess whether differences in geology between this and other areas in the reserve corre- spond to differences in vegetation. My preliminary assess- ment would be that, if these differences exist, they would be more quantitative than qualitative in nature, the mixed forest found on these hills being similar to mixed forest found on brown sands or in the Iwokrama Mountains. The expedition walked to the end of a 5 km long tran- sect that started at Pakutau Falls on the Siparuni River, proceeded in a southerly direction, ended near the highest point in the Pakutau Hills (~400 m elevation), and began collecting along the most distant portion of the transect. The next day we collected along the part of the transect closest to the Siparuni River. We then made riparian collec- tions in the area surrounding Pakutau Falls and upstream as far as Ireng Creek, finding typical rheophytic and ripar- ian vegetation such as Mourera fluviatilis, Psidium, and Coccoloba. Finally, we made riparian collections along the Siparuni River from Pakutau Falls downstream as far as Levai Falls before our return to Kurupukari to process plants and to work on identifications. On 14 November we collected in the interior of a Mora forest adjacent to Kurupukari?Annai road, 22 km southwest of Kurupukari. We then traveled by boat to a new transect along the Burro- Burro River (approximately 1 km upstream from Duckla Falls). The transect was 5 km long and proceeded in a westerly direction. The ter- rain was quite flat, the soils were brown sands, and the vegetation varied between seasonally flooded palm swamp forest (Mauritia, Oenocarpus, and Jessenia) and mixed forest. During the next two days we collected along the farthest portion and in the near portion of the transect, where a tayra (Eira barbata) was seen. At night a labaria (Bothrops atrox) interrupted the Amerindians? card game under the tarp and was quickly dispatched. A limited fuel supply forced us to abandon a plan to collect along the partially completed transect near Sand- stone on the upper Burro- Burro River. Low fuel supplies at base camp limited all further collections in areas accessible by road, but collections were made near camp before our return to Kurupukari to process plants. The following day the expedition made collections approximately 8 km from Kurupukari along the Kurupu- kari?Annai Road. We then traveled by Land Cruiser 34 km along the Kurupukari?Annai Road to set up camp at the head of a transect leading 4.5 km to the base of the Iwokrama Mountains. This transect travels around the pe- riphery of Humiria- Clusia scrub and passes through palm swamp and Mora forest. We walked approximately 0.5 km over crude machete- cut trail up drainage into the Iwokrama Mountains and ascended the 800 m peak south of camp. No significant elevational gradient in floristic composition was detected. The forest is a mixed forest on brown sandy loam with numerous rock outcroppings. Black and red poi- son arrow frogs (cf. Phyllobates) were seen in the forest. Further collections were made along the machete- cut trail and in a creek bed 0?3 km east- southeast of base N U M B E R 9 7 ? 2 5 camp. Licania, Clathrotropis, Swartzia, and Cassia were common canopy elements in the first 2 km of the creek, whereas the midstory was dominated by unknown Melia- ceae. Near the top of the drainage, 2?3 km east- southeast of camp, the canopy elements of the forest did not ap- pear to differ greatly from those in lowland mixed forest in other parts of the reserve or throughout the areas visited in the Iwokrama Mountains and particularly in the gorge of the unnamed creek adjacent to camp. However, the un- derstory, herbaceous, and epiphytic elements did appear to be characteristic of a distinctly more mesic forest than other parts of the reserve. Plants such as Cephaelis and other Rubiaceae, Sinningia and other Gesneriaceae, ar- oids, orchids, tree ferns and filmy ferns were encountered commonly here that were not seen elsewhere in the re- serve. We examined and photographed petroglyphs newly discovered by Daniel Allicock, Baptist James, and crew. On the highest peak in the Iwokrama Mountains (1,000 m) we saw a labaria guarding a petroglyph rock (because this snake is highly poisonous it was quickly dis- patched), and a harpy eagle near a porcupine it had killed, which we photographed. A cut trail from the summit to a large rock outcropping immediately below the summit affords a view of Makarapan Mountain, the Annai area, and the area extending to the Essequibo River. We returned to Kurupukari by Land Rover on 27 No- vember and collected along the road near base camp. Near the road we saw a tapir that apparently was unaccustomed to people and allowed us to approach closely. We then collected along the A?B transect starting at Kurupukari? Annai Road (4?35?11.6?N, 58?44?39.3?W) and heading in a 105 degree direction. The transect started in Mora for- est (in which we made more collections), passed through mixed forest, and ended in Eperua forest on white sand. Finally, we moved to Surama to collect in a savanna area, before our return to Georgetown. The next field trip to Iwokrama was planned to take advantage of the onset of the rainy season when more plants were expected to flower. triPS 3?4: mabura hill; ceiba enVironment al center 30 DecemBer 1995 To 14 January 1996 (maPs 1 anD 2) This collecting trip began at Mabura Hill, located in Demerara Timbers Ltd. Forest. The expedition moved south on the Mabura Hill?Kurupukari Road and made collections in dense forest on white sand. On 1 January we collected 3 km south of Tropenbos Field Station in disturbed open area on red gravelly clay. Collections were also made 20 km south of Mabura Hill on the Mabura Hill?Kurupukari Road, in dense forest on white sand, with Eperua, Peltogyne, and Licaria. The team then moved to an area 32 km south on the Mabura Hill?Kurupukari Road where the environment changed to dense forest on brown sand. The next day more collections were made in the disturbed open areas of Tropenbos Field Station. The expedition then returned to an area 3 km south of Mabura Hill and proceeded 60 km north on the Mabura Hill?Linden Highway where we collected in disturbed roadside vegetation on white sand. Final collections were made at the CEIBA (Conser- vation of Ecological Interactions and Biotic Associations) Research Centre, adjacent to the Soesdyke?Linden High- way. The Center was populated by Muri scrub (Humiria) vegetation on white sand and Mauritia swamp forest on white sand with Mauritia, Pentaclethra, and Mora. triPS 5?6: P aruima anD P aramaKa toi 22 January To 27 feBruary 1996 (maPs 3 anD 4) A month- long plant- collecting trip to Paruima in the northwestern Pakaraima Mountains was followed by a one- week trip to Paramakatoi in the southern Pakaraimas with a team of bryologists and lichenologists. In the past the Paruima area has been collected only by Tim McDow- ell and Adrian Thompson, and Paramakatoi only by Lynn Gillespie. Both of these areas offer access to large expanses of premontane and montane primary tropical forest. In addition, lowland shrub savanna is close to Paramaka- toi in the direction of Kato and the Paruima area offers a large number of habitats associated with the summits of the tepuis that surround the village. Logistics problems necessitated flying into Kamarang before being transported by boat upriver into Paruima. Af- ter gaining approval of local authorities and finding a guide, we planned to collect in the Kamarang area for two days. The first days were spent along the trail between Kamarang and Waramadon (upstream on the Kamarang River from its confluence with the Paruima River). The trail began in sec- ondary forest and quickly passed into primary premontane forest dominated by Mora gongrijppii, Licania, Caryocar, and Aparisthmium. On the second day we collected along a trail 3 km north of Kamarang on the Mazaruni River. The trail passes primarily through primary forest, but also through areas of overgrown cassava plantations, and leads from the river to farms and small- scale mines. 2 6 ?

N U M B E R 9 7 ? 2 9 After two days of travel we reached Paruima. With James Chambers we collected along the trail across the Kamarang River from Paruima leading north to Wari- matipu, Holitipu, and Kaikan. The trail ascends from the river through secondary and primary forest and leads to a number of small areas cleared for farming. Collections were made as far as the base of Warimatipu, which is cov- ered by semi- open, naturally disturbed forest on unstable rock slopes. With James Chambers and three other workers we traveled by dugout several kilometers upstream on the Ka- marang River to a trail leading to the Utshi River and Ven- ezuela. The trail follows the course of the Kamarang River through a canyon between two tepuis and crosses a num- ber of side canyons, such as Kumarow, that are crossed by walking high above the river on very large boulders that fill the riverbed. The trail then passes abruptly from forest into savanna as the summit is reached. The trail is very beautiful and offers an excellent opportunity for develop- ment for ecotourism. After ascending the trail to the Utshi River tepui sum- mit, we camped in a gallery forest along the Utshi River and collected in the savanna and gallery forest near camp. The next day we hiked from camp to a site several kilometers south near the Great Falls on the Kamarang River and collected in the savanna and gallery forest be- tween there and camp. This area offers spectacular views of the waterfalls and high tepuis in the area, including Il- lutipu, Waukauyengtipu, and, in good weather, Roraima. We collected in a savanna, gallery forest, and seep area near the border of Venezuela along the trail and in the forest surrounding the first camp on the Kamarang River before returning to Paruima to process the plants. The expedition then traveled to a large tepui area about 10 km north of Paruima called Waleliwatipu or Aymatoi, contiguous with Holitipu. We collected in savanna, gallery forest, and rock outcroppings between Uluk Creek near the southern edge of Waleliwatipu, and in gallery forest, savanna, and rock outcroppings near an airstrip built by a Canadian mining company in the vicinity of Mount Yuro- ban, a flat- topped forested promontory protruding above Holitipu. The gallery forest and rock outcroppings in the area of the airstrip provided a large number of unique plant species not seen elsewhere on this trip. After another trip back to Paruima to process plants, we collected in premontane forest in the area between Pa- ruima and Konuktipu (contiguous with Kolodokyengtipu). This area is dominated by dense primary forest interspersed with successional areas associated with cassava cultiva- tion. It also has naturally disturbed areas and seeps at the base of cliffs with elements such as Pothomorphe, Mucuna, Cissampelos, Mendoncia, and Pavonia. We then collected along the Kamarang River near Paruima, along the Pa- ruima River upstream several kilometers to large rapids, and in the forest area between Paruima and Illubia Creek. Aside from a giant anteater and the usual assortment of monkeys, we saw few mammals on this trip. The birdlife, however, was quite impressive, with a whole assortment of hummingbirds and many frugivorous (fruit- eating) birds such as trogons (bright red and green), bellbirds (white and brown with a wattle like a turkey and a call like a car horn that can be heard for kilometers), cotingas (iridescent blue and purple), Cock- of- the- Rock (day- glow orange), oropendulas (like orioles), and tanagers. We returned to Georgetown, secured permits, hired workers, and traveled to Paramakatoi where we met with a team of lichenologists and bryologists, who had arrived from Kaieteur Falls: Paul DePriest (Smithsonian), Harry Sip- man (Berlin), Angela Newton (Smithsonian), Solis Stenroos (Helsinki). Together we collected along the trail from Para- makatoi to Paramaktipu. The trail passes through disturbed vegetation into primary forest and climbs several hundred meters to the top of Paramaktipu. We also collected along the trail from Paramakatoi to Maikwak and Kowatipu, which passes through primary forest and occasional aban- doned cassava plantations, and along the trail from Para- makatoi to Karibon Creek, which begins in secondary forest and descends a few hundred meters through primary forest, before returning by rough trail to Paramakatoi. From Paramakatoi we collected along the trail to Yowang and Monkey Mountain. The trail descends sev- eral hundred meters, parallels a stream for several kilome- ters, and returns to Paramakatoi by a different route. Finally, we collected along the trail between Paramak- atoi and Kato. The forest savanna ecotone occurs about midway between the two villages. Collections were made in the forest near Paramakatoi. Mora gongrijpii dominates in low areas and premontane mixed forest with Pouteria, Aspidosperma, and Licania dominant in upland areas. Because the short runway at Paramakatoi makes tak- ing off with heavy payloads difficult, half the group had to walk to Kato, a distance of about 20 km by air, before the entire group was able to catch the flight to Georgetown. triP 7: iWoKrama interna tional rainforeSt reSerVe 14 march To 16 aPril 1996 (maP 4) This trip to the Iwokrama Rainforest Reserve was made as part of a continuing effort to document the flora of the area. Bruce Hoffman, who was researching 3 0 ? S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y Heteropsis and its potential as a non- timber forest prod- uct, joined this trip. Emphasis was put on documenting phenology by re- collecting in areas previously inventoried; this allowed for collecting plants in flower that may have been collected on previous expeditions in fruit. Excursions were also made to previously uncollected areas, such as an outlier of the Iwokrama Mountains, Sandstone on the upper Burro- Burro River, and floodplain areas adjacent to the Essequibo River near Turtle Pond. The trip began with a flight into Annai to meet with Fred Allicock. After a quick trip to Surama to collect field assistants, we traveled to Kurupukari by Land Rover. Af- ter preparing the boat with a 40 hp engine, food, and sup- plies, we proceeded upriver to Akromukru Falls on the Essequibo River. Plants were collected along the first half of the 5 km Akromukru transect perpendicular to the Es- sequibo River (Figure 3). The first 2 km from the river are dominated by Mora forest, the next 2 to 3 km are Mora and mixed forest occurring together with Chlorocardium, and the remainder of the transect is dominated by mixed forest with Chlorocardium. Two harpy eagles, an adult and a not fully fledged juvenile, were observed at km 2.3, indicating the presence of a nest nearby. The camp was moved to an area near Ladysmith Creek and collecting continued along the first 2 km of the transect. On the first half of this 5 km transect Mora occurs together with mixed forest with Chlorocardium, Licania, and others species. There is also a good deal of semi- disturbed ?liana forest.? After about a week in this area we returned to Kurupukari by boat and made prepa- rations for a trip to Moco Moco II Creek. Leaving the boats, we traveled by Land Rover to Moco Moco II Creek, 32 km southwest of Kurupukari along Ku- rupukari?Lethem Road. We set up camp and began col- lecting in and around the forest along the 3.7 km transect, beginning at the road near camp and ascending to the sum- mit of an unnamed outlier of the Iwokrama Mountains. Most of the first part of this transect is dominated by areas of poorly drained white sand with Mora, Phenakosper- mum, Eperua, Catostemma, and a prominent palm mid- story with Oenocarpus and Euterpe. Along the steep rock slope that ascends the outcrop, Pentaclethra, Symphonia, Chrysophyllum, and Parinari dominate. The mixed forest on this mountain differs somewhat in composition from that found on brown sands in other parts of the reserve. The forest is slightly more open with a prominent palm (Bactris and Scheelea) understory. Bellbirds were heard here, the only place other than the Iwokrama Mountains proper where they have been heard in the reserve. The expedition returned to Kurupukari and prepara- tions were made for a second boat trip, this time to Turtle Pond on the Essequibo River and Sandstone on the up- per Burro- Burro River. Collections were made along a transect to cover as much habitat over this 3.5 km sec- tion as possible. Most of the first 2 km of the transect was dominated by mixed forest on brown sand with Mora, Carapa, Chlorocardium, and Licania. Detours from the Turtle Pond transects were taken at km 2.4 and 0.9 km to smaller lakes between the transect and the Essequibo River. The lakes become channels of the Essequibo River during the rainy season and harbor a large number and diversity of fish, including arapaima. The forest adjacent to this area is of low stature and relatively low diversity and is adapted to flooding and siltation. Gustavia, Sym- meria, an Eschweilera species, and numerous species of Myrtaceae dominate. We traveled by boat down the Essequibo River and up the Siparuni and Burro- Burro Rivers to Sandstone, the site of an abandoned gauging station and terminus of the aban- doned Mahdia?Sandstone Road. We continued collecting along a 2.7 km transect beginning at Sandstone on the Burro- Burro River. The transect began in flat Mora forest on brown sand near the river and passed over several hills figure 3. Brassavola martiana Lindl. (Orchidaceae), Clarke 1366. N U M B E R 9 7 ? 3 1 with rock outcroppings with Ananas, Heliconia, and as- sociated herbaceous vegetation. Most of the transect away from the river was dominated by mixed forest on brown sand, although the transect did cross the abandoned road where dense secondary forest dominates. On 3 April we left the northern part of Iwokrama and returned to Surama. Two transects heading northwest and southeast from the Kurupukari?Lethem Road near the southwestern border of the reserve were our next areas to sample. The mixed forest in this part of the reserve had a somewhat different composition and perhaps a more sea- sonal character; it was dominated by Goupia, Vitex, Vi- rola, Ceiba, and Cedrela. Our final plant collecting for this trip was in the savannas near Surama. We then returned to Georgetown. triP 8: eaStern KanuKu mount ainS 21 may To 15 June 1996 (maP 5) This trip to Dadanawa Ranch, the Rupununi River, and the Eastern Kanuku Mountains was made to help document this diverse and poorly known area. The South Rupununi and Kanuku Mountains offer a diversity of habitats for collecting, including gallery forest, savanna, bush islands, xeric scrub, epilithic vegetation, seasonal forest, and a number of types of high- canopy rainforest in and surrounding the mountains. Moisture gradients occur from north to south, with very mesic forest occurring on the northern slopes of the Kanuku Mountains and drier forest on the southern slopes. Elevation gradients occur over about 1,000 m of vertical relief in the mountains. Rain was very heavy throughout this trip but did not impede collecting or travel. In fact travel on the Rupununi River south of Sand Creek Village is possible only during the rainy season. The trip began with travel by Guyana Airways Corpo- ration (GAC) Twin Otter from Timehri to Lethem, where we were met by Duane DeFreitas, and we moved on into Dadanawa Ranch by Land Rover. Our first collections were made in savanna and gallery forest near the ranch compound. Over the next few days we collected in gallery for- est along the Rupununi River and in Natun Bush Island. Plant diversity in the South Rupununi Savanna consists of a heterogeneity of habitats including savanna proper, gal- lery forest, granite domes, and bush islands. Bush islands are areas of high- canopy evergreen forest surrounded by savanna, the presence of trees attributable to local edaphic conditions that allow for roots to penetrate the hardpan. We also collected on Tautowan Mountain, a granite dome with xeric vegetation on exposed granite (Cnidosculus and Melocactus, e.g.) and dry forest vegetation at the base (Fagara, Cochlospermum, and Lippia, e.g.). On 26 May we traveled to Sand Creek by aluminum boat. We collected in savanna and savanna?forest mosaic north of Sand Creek Village (although heavy rains during this period resulted in extensive flooding in the savanna surrounding the village), and in savanna, dry forest, and evergreen forest to the east of the village. From Sand Creek Village we traveled by boat north along the Rupununi River to Crabwood Creek. Walking from camp, we reached an unnamed peak of the Kanuku Mountains 10 km to the east and collected on the summit and slopes of the mountain. On 31 May we traveled by boat south along the Ru- pununi River to the westernmost extension of Makawatta massif. We cut a trail to the top of the mountain and col- lected among scrub vegetation at its summit and closed canopy forest on its slopes. We then collected near the camp in forest near Crabwood Creek that was soon to be inundated by rising water levels; Mora, Ceiba, and Astro- caryum were dominant. Traveling about 15 km up the Maparri River to the base of a waterfall, we made camp and collected along the river. The forest on the south bank of the Maparri above the waterfall is particularly mesic, with an abundance of epiphytic filmy ferns, orchids, and bromeliads. For the next three days we continued to collect along the Maparri River as far as 10 km west and 8 km east of camp. We cut trails to the tops of two unnamed peaks, 3 km north and 2 km south of camp, and collected on the summits and slopes. On 9 June malaria forced the group to begin return- ing to Dadanawa Ranch. Because of engine problems and the very strong current of the Rupununi River in flood stage, the trip back to Crabwood Creek took 24 hours of uninterrupted travel. Engine repairs at dawn allowed for good progress to be made thereafter. After a rest at Crabwood Creek, the group progressed to Dadanawa by boat, to Lethem by Land Rover, and back to Georgetown by GAC Twin Otter. Plants and goods were sent back to Georgetown by truck. triP 9: KuYuWini riVer 29 June To 30 July 1996 (maP 5) On this trip to the Kuyuwini River in southern Guy- ana, I was accompanied by two students, Sally Adkins from the Smithsonian Institution and Calvin Bernard from the 3 2 ?

Also included were Regis James from Aishalton and Claudius Perry from Marunawa, two Wap- ishana workers skilled in all aspects of plant collecting, and several other workers from Aishalton. The Kuyuwini River area is of interest because it is part of the poorly known and scarcely collected southern Guyana forest. Access to the forests of southern Guyana is difficult because the area is essentially unpopulated. The only starting points are at Gunn?s Strip and several points on the South Rupununi sa- vanna. Travel from the South Rupununi is the less expensive option, but is more arduous because extensive walking is required. On this trip, rations, supplies, fuel, and the out- board (~680 kg) were carried by people or by bullock from Aishalton over Marudi Mountain to the landing on the Kuyuwini River, after which the group travelled by dugout. The trail from Aishalton to Kuyuwini Landing is an old es- tablished trail that was also used by Richard Schomburgk in the 1840s. It begins in the savanna, passes through the sa- vanna?forest ecotone ?bush mouth? about 16 km southeast of Aishalton, and continues another 48 km through high- quality primary tropical forest for another 48 km before reaching the Kuyuwini River. It passes over Marudi Moun- tain and within 8 km of Bat Mountain, an eroded granite- dome inselberg with bare rock on top and scrub vegetation at its base. To find our position and successfully cut trail to the mountain, we used a combination of GPS, which neces- sitated climbing trees to get a signal, and orienteering with 1:50,000 series topographic maps and compass. The trip began with a GAC Twin Otter flight from Timehri to Lethem. High water prevented travel in or out of Lethem and so over the next four days collections were made around Lethem in savanna and gallery forest of Ta- kutu River. When Eddie Singh?s truck arrived on 4 July the expedition proceeded to Dadanawa Ranch. High wa- ter levels in the Arakwai Creek prevented travel to Aishal- ton, so once again collections were made in the area: in savanna, gallery forest, and bush islands on the road from Dadanawa Ranch to Shea and near Natun Bush Island. Aishalton was finally reached by tractor and arrange- ments were made to hire bullocks and workers in the vil- lage. The team walked from Aishalton to Regis James farms at bush mouth (~16 km) and from bush mouth to a point in the forest midway between Marudi Mountain and Kuyuwini Landing. Lack of forage for the bullocks in the forest impeded their progress, as did flooding in the Eu- terpe swamps. Kuyuwini Landing was finally reached on 13 July and collections were made near the landing and in forest along the trail to Marudi Mountain and Aishalton. As further collections were made along the Kuyuwini River downstream (east) of the landing, the team repaired the large and small dugouts and equipped the large dugout to accept a 15 hp engine. We then traveled in the two dug- outs from Kuyuwini Landing upstream?the large dugout with engine carried equipment and supplies and towed the small dugout with passengers. Extensive flooding in the area made finding even a provisional camp difficult. Continued travel up the Kuyuwini was impeded by many treefalls and vegetation (Inga and Astrocaryum) blocking a narrow channel that was hard to distinguish from adja- cent flooded forest. Camp was made at a high spot on the river bank at a giant river otter midden. The expedition cut trail and collected in terra firme mixed forest 0?2 km northwest of camp and in riparian habitats along the Kuyuwini River 0?5 km west of camp. The camp was moved upstream to a landing at the termi- nus of a trail from Parabara Savanna and further collec- tions were made near camp, in forest and isolated savanna areas 0?5 km north of camp, and along the river 0?3 km west of camp. We returned by dugout to Kuyuwini Landing and proceeded on foot to a point in the forest several kilo- meters south of Marudi Mountain. There we cut a trail from camp to the foot of Bat Mountain and ascended to a point where the vegetation ended, where further prog- ress was made impossible by blue- green algae on rocks made slippery by the rainy season. We collected in scrub and xeric vegetation (Furcrea, Melocactus, Cnidosculus, Clusia, etc.) and enjoyed a spectacular view from horizon to horizon of uninterrupted, undisturbed, and uninhabited primary tropical rainforest. Completing our work on Bat Mountain, we spent a long grueling day walking from the camp south of Marudi Mountain to bush mouth, approximately 32 km. Our return trip continued on foot to Aishalton, by tractor to Arakwai crossing, and to Dadanawa and Lethem by Land Rover. Plants and goods were left in Lethem to be trans- ported by Eddie Singh?s truck to Georgetown, while per- sonnel returned to Georgetown by GAC Twin Otter. triP 10: iWoKrama interna tional rainforeSt reSerVe 17 sePTemBer To 5 ocToBer 1996 (maP 6) This Iwokrama trip was specifically designed to col- lect in previously uncollected areas near the base camp and Turtle Mountain on the Essequibo River, and to collect intensively at higher elevations in the Iwokrama Moun- tains. Two newly cut transects were sampled, one near the base camp on the Kurupukari?Annai Road in mixed 3 4 ? S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y MAP 6.

N U M B E R 9 7 ? 3 5 forest on undulating terrain, and one from the Essequibo River through forest prone to flooding and heavy siltation to an exposed area at the top of a cliff on Turtle Moun- tain. A camp established at the top of the drainage in the gorge between the highest peaks in the Iwokrama Moun- tains allowed more effective collecting. Carrying rations and equipment from the road to the base of the mountains and up the gorge is difficult, but the time needed to climb the mountains from the camp at the bottom of the gorge, three hours each way, was too long to allow for sufficient time to collect on the mountains. This work was carried out with the assistance of several Macushi and Wapishana workers from Surama and Kurupukari. The trip began with a flight from Georgetown to Annai by GAC Twin Otter and travel by Land Rover to Kurupukari base camp, while rations and equipment was transported via Eddie Singh?s Bedford truck. Our first col- lections were made along a transect beginning on the Ku- rupukari?Annai Road. The trail passes through terra firme mixed forest interrupted periodically by Euterpe swamp forest in depressions. After travel by Land Cruiser to the head of a trail ap- proximately 48 km southwest of Kurupukari, we made camp at the top of a gorge between the highest peaks of the Iwokrama Mountains. We collected in a streambed at the top of the gorge, climbing up over a series of waterfalls until the stream diminished into a number of seeps on the south- facing north slopes of the gorge on the peak. The gorge is very mesic and supports a high diversity of epi- phytes and rheophytes. On 23 and 24 September we climbed from camp at the top of the gorge (300 m) to collect on the summit of the highest unnamed peak in the Iwokrama Mountains (1,000 m). The vegetation on the summit is characterized by a higher number and diversity of epiphytes (Figure 4) and a more developed understory of palms and shrubs. The trees tend to be of lesser girth and somewhat lower stature than lower forests, but are otherwise similar to those found in mixed forests at lower elevations. Views are available from just below the summit of granite outcroppings of Makara- pan Mountain and the twin peaks on the south side of the gorge on one side of the mountain, and the Essequibo River and Apoteri on the other side. For the next five days we cut a line up and collected on the twin peaks on the south side of the gorge. On 30 September we collected in Humiria (n.v. ?muri?) scrub along the road at the beginning of the trail to the mountains 45 km southwest of Kurupu- kari before our return to Kurupukari by Land Cruiser. The expedition then traveled by boat from base camp at Kurupukari to the beginning of a transect on the Essequibo River that leads to the summit of Turtle Moun- tain. The trail ends at the summit in Clusia/Erythroxylum scrub forest on the top of a cliff that affords a view north and east across the Essequibo of Aikawan Mountain, the Canister Falls area, and other mountains. We collected in scrub forest on the summit, semi- disturbed ?liana? forest on upper slopes, and along the river for several kilometers north of the beginning of the transect. We also collected on the lower slopes of Turtle Mountain in mixed forest, along the river between the beginning of the transect and base camp in seasonally inundated Mora forest, and in low- canopy seasonally flooded and siltated forest. Finally, we collected along banks and on sand islands of the Essequibo River north of its confluence with Tiger Creek. This part of the river is characterized by having many rapids and channels. The islands that occur in this part of the river support a more open forest with more xeric vegetation than that found on lower parts of the Es- sequibo River. We prepared our plants and equipment for shipping by truck to Georgetown and traveled by Land Cruiser to Annai before the final trip by GAC scheduled Twin Otter service from Annai to Timehri. triP 11: Gunn?S StriP, choDiKar, Kamoa, anD uPPer eSSequibo riVerS 21 ocToBer To 26 novemBer 1996 (maP 7) Floristically, the far southern area of Guyana south of Gunn?s Strip is among the most poorly known, and general collecting in this area will help to augment our figure 4.

N U M B E R 9 7 ? 3 7 knowledge of many plant species. The vegetation map of Guyana produced by Smithsonian lists as ?floristic com- position unknown? both the lowland evergreen forest found in this area and the lower montane evergreen for- ests found in the Acarai, Kamoa, and Wassari Mountains on the Brazilian border. When working in this area, one notes a nearly complete turnover in species composition in these forests compared with forests in northern and cen- tral Guyana, in Iwokrama, for example. Thus, although forests in northern and central areas have a typical Gui- anan composition, the floristic affinities of those in the south are found in the eastern Amazon. What causes this difference in floristic composition is an interesting ques- tion. From Iwokrama, Mabura, Kartabo, and other areas in the north to the Brazilian border in the south there is an uninterrupted expanse of lowland evergreen forest with fairly uniform soils and geology and very uniform climate. Without any meaningful edaphic or climatic gradients, then, this marked difference in species composition must be attributed to historical factors. Work in southern Guyana is made difficult by the re- moteness of the area and difficult logistics. The only air- strip, and the only human habitation, is at the Wai Wai village of 200 people at Gunn?s Strip. Air charters are expensive because of the distance from Georgetown and the reduced payload needed to accommodate extra fuel (maximum weight for an Islander is 1,200 lb [544 kg] and this includes fuel, pilot, passengers, and cargo). This expedition was carried out in conjunction with a Royal Ontario Museum mammal collecting expedition staffed by Burton Lim, Eamon O?Toole, and Charles Robertson. In addition, George Simon of the Ministry of Amerindian Affairs accompanied SI and ROM personnel. The total weight of people and equipment was 1,678 kg; three Is- lander charters were needed traveling into Gunn?s Strip and two traveling out. Assistance in plant collecting was provided by two continuing Wapishana workers, Regis James from Aishal- ton and Claudius Perry from Marunawa, and three Wai Wai workers, Marifa Marawanara, Wachana Yaymochi, and Mark Sose (Figure 5). Regis James and Claudius Perry are thoroughly trained in plant collecting and general bush skills and the Wai Wai workers are undoubtedly the best available people in Guyana for working in remote loca- tions, having extraordinary bush skills and more indig- enous knowledge about plants than any other Amerindian group in Guyana. Over the course of this five- week trip we made 607 plant collections, mostly in duplicates of six. The value of these collections is augmented by the fact that they were collected in very remote locations and because a good deal of effort was expended in collecting taxa that are difficult to collect: canopy trees, lianas, and epiphytes. By 24 October both the Royal Ontario Museum and the Smithsonian teams had been flown into Gunn?s Strip in two Guyana Defense Force (GDF) Islanders, splitting the cargo between the two planes. Arrangements and prepara- tions were made for the trip to Chodikar River and Acarai Mountains, and the first collections of the trip were made in a forest on the east bank of the Essequibo River opposite Gunn?s Strip on the first kilometer of trail to New River. Fuel, rations, equipment, and nine people then traveled in two large dugouts, powered by 15 and 25 hp engines and owned by the village, from Gunn?s Strip upstream on the Essequibo River to its confluence with the Kamoa River. Travel continued upstream past the confluence of the Sipu and Watuwau Rivers to Chodikar River. Passage became increasingly difficult as the channel narrowed and became shallow. Treefalls about every 100 m were cleared with cut- lasses and axes. Camp was made on Chodikar River several kilometers from the Brazilian border. The expedition began to cut a line from camp into the Acarai Mountains with the objective of collecting on Chodikar Mountain, a granite inselberg likely to support a number of disjunct, xerophilous species. We collected as we cut the trail, mostly in Euterpe swamp forest, which is very characteristic of the extensive poorly drained areas of southern Guyana. On the third day we crossed a small creek and passed into terra firme forest and then into a semi- open forest on poorly drained white sandy clay with abundant Myrtaceae and Hymenophyllaceae. We moved our camp inland to a creek at the base of the Acarai Mountains to figure 5. Loading the Wai Wai dugout canoes at Gunn?s Strip. 3 8 ?

We continued collecting and cutting a line in the direc- tion of Chodikar Mountain. The line passed over a low ridge, crossed a creek, and climbed up very steeply onto a ridge that was partially covered with a Clusia/Erythroxy- lum scrub forest. As we continued we followed ridges as much as possible, but occasionally descended into ravines. More mesic elements such as ferns, gesneriads, and Her- rania are found in the ravines, whereas a somewhat less mesic mixed forest is found on slopes and ridges. The line passed through a low canopy scrub forest with Erythroxy- lum and Myrtaceae on a ridge with numerous epiphytic orchids and Ericaceae. Guianan Cock- of- the- Rock was observed and photographed near a cliff area in a ravine. As we cut a line toward Chodikar Mountain through sim- ilar ridge and ravine mixed forest habitat, progress was slowed by the time needed to walk over very difficult ter- rain to the point where line cutting ended the previous day. One Wai Wai worker, in bare feet, nearly stepped on a modestly sized bushmaster. On 5 November we were within 2 km of Chodikar Mountain, which was clearly visible from several points as a half- forested and half- rock face mountain, but complete depletion of rations at our remote camp at the base of the Acarai Mountains forced a return to main camp. The entire party of botanists, Amerindians, and mammalogists trav- eled by dugout down the Chodikar and Essequibo Rivers to Marifa Marawanaru?s abandoned farm on the Essequibo River between the confluences of the Sipu and Kamoa Riv- ers, paddling to conserve diminished fuel supplies. Travel upstream on the Kamoa River was impeded by many treef- alls across the channel. We made camp on the north bank of the river near an abandoned farm and relatively close to several outliers of the Kamoa Mountains. From the new camp we cut a line to the summit of an unnamed outlier of the Kamoa Mountains 2 km north of camp (520 m elevation) and collected in scrub forest on granite outcroppings at the summit, in mixed forest on boulder- strewn slopes below the summit, and on slopes in both high- canopy dense forest and low- canopy Clusia/ Myrtaceae/Erythroxylum scrub forest. The forest between camp and the unnamed outlier contains both Vochysiaceae- dominated high- canopy forest and semi- open forest on poorly drained white sand with Mauritiella, Catostemma, and Clusiaceae. We also collected in riparian vegetation along the Kamoa River 0?6 km west of camp and on the summits and slopes of two additional unnamed outliers of the Kamoa Mountains 2 km south of camp. We traveled north on the Essequibo River to an area north of its confluence with the Onoro River, an aban- doned Konashen village, and to Konashen Rapids due east of Zibingatzako Mountain, and made camp along the river. We cut a line and collected 0?3 km east of camp in the direction of Zibingatzako Mountain in dense forest on relatively flat terrain. Unlike the area between Cho- dikar River and the Acarai Mountains, this area is only dominated by Euterpe swamp forest in the immediate vi- cinity of streams. After our cut line reached the base of Zibingatzako Mountain, we climbed to one of the sum- mits of the Zibingatzako massif and collected in Clusia scrub forest on rock outcroppings. We also collected in riparian vegetation along the Essequibo River several kilo- meters south of camp and 0?5 km north of camp, before returning to one of the summits of the Zibingatzako mas- sif and collecting in scrub forest on granite outcroppings. Finally, we returned by dugout to Gunn?s Strip (Figure 6) and transported all collections, equipment, and personnel to Georgetown by GDF air charter. triP 12: KWit aro anD uPPer reWa riVerS 2 feBruary To 7 march 1997 (maP 7) Inspiration for this Kwitaro?Rewa trip came as a result of flying from Gunn?s Strip to Georgetown and figure 6. Marifa Waruwanaru (left) and Wachana Yaymochi (right) at Chodikar River camp making the paddles that were needed to get back to Gunn?s Strip with a broken outboard engine. N U M B E R 9 7 ? 3 9 observing a number of rugged, highly eroded granite insel- bergs between the Kwitaro and Rewa Rivers and between the Rewa and Essequibo Rivers at about the latitude of the Great Falls of the Rewa River in southern Guyana. These inselbergs appear to be the eastern remnants of the Ka- nuku Mountains. The fact that the inselbergs and the sur- rounding areas should support a number of highly diverse plant communities, that this area had not previously been collected, and that exploratory timber concessions have been granted to multinational logging companies covering this entire area argue strongly for expending serious effort to explore and document the plants of this part of Guy- ana. A Conservation International Rapid Assessment Pro- gram team made only a cursory investigation of the lower Rewa River, traveling by boat from the Rupununi River. Access for this expedition was made from the South Rupununi Savanna via an established line that begins at Shea Village and ends at the Kwitaro River. Although trav- eling by boat from the Rupununi River would be easier, the lower Rewa River has a different character than the upper part because it passes through flat terrain and has many meanders and oxbow lakes. The Kwitaro and upper Rewa Rivers, on the other hand, provide more immediate access to the inselbergs and have straighter channels with many rapids and waterfalls. All fuel, rations, and equip- ment had to be carried by people or bullocks from Shea Village to the Kwitaro River, a distance of approximately 32 km. In addition, dugouts had to be lined through the rapids on both rivers, and the very heavy dugouts had to be portaged on newly cut lines around several sheer- drop waterfalls on the Rewa River. This area was visited regu- larly during the balata (Manilkara) bleeding (when latex is gathered from carefully placed slashes in the bark) era in the 1970s and has been prospected sporadically for gold in the past 10 years, but at this point it has no permanent human habitation and is too far from the villages on the South Rupununi Savanna or Rewa Village at the mouth of the Rewa River to be visited by Amerindians paddling ca- noes. These two rivers still have abundant populations of Podocnemis river turtles, arapaima and other highly desir- able fish species, giant river otters, and perhaps a remnant population of the Amazonian manatee. Assistance on this expedition was provided by Claudius Perry of Marunawa, Romeo Williams of the Bartica area, and four workers, all former balata bleeders, from Shea: Paulin Griffith, Myles David, Melchior Augustine, and Malkie Peters. Extra workers were needed for this expedi- tion: seven people would be the minimum number needed to move a large dugout canoe across a portage, lines had to be cut for portages and to gain access to the inselbergs, and the entire expedition (680 kg) had to be carried from Shea Village to the Kwitaro River. We made 701 collec- tions of fertile taxa on this expedition, mostly in replicates of six. Many of these were collected from difficult to col- lect canopy trees, epiphytes, and lianas by a technique that combined the use of tree- climbing spikes with extendable clipper poles to reach and collect in the canopy. Expedition members met in Dadanawa and went on to Shea Village where arrangements were made for more workers and eight bullocks to transport fuel, rations, and equipment to the Kwitaro River. We traveled by foot from Shea to the Kwitaro River over a well established line of somewhat less than 32 km that passes through savanna and forest over relatively flat terrain to a landing on the Kwitaro River. While repairs were being made to the dug- outs and three workers returned to Shea for additional supplies, collections were made in the vicinity of Kwitaro Landing (Figure 7). On 8 February the expedition party of seven left Kwitaro Landing in one large dugout, towing a smaller dugout with fuel and two people. The water level was higher than usual, allowing for fairly easy passage through rapids just downstream from the landing. There were no other rapids after the first set below the landing, but travel was slowed somewhat because the river has a very narrow and shallow channel and broad meanders. After camping near an eastern outlier of the mountains, travel continued downstream on the Kwitaro River to its confluence with the Rewa River (Figure 8) and then upstream on the Rewa River, which has a deep, clear channel. At the end of the day the boats were pulled through the Coruna Rapids us- ing rope and we made camp on the east bank just below figure 7. Hymenocallis tubiflora Salisb. (Liliaceae), Clarke 3475. 4 0 ? S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y the Great Falls, a complex series of rapids with several 2?3 m sheer- drop falls. We observed several large anacondas on the banks of the Kwitaro River. Over the next few days we collected in the forest near camp, on rock outcroppings above and below the Great Falls (Figure 9), and on an island above the Falls. We also scouted the old 400 m long portage, used during the ba- lata era, around the Falls starting on the west bank below the Class III rapids below the Falls. We cleared this line to carry rations, fuel, and equipment around the Falls, and cleared another shorter line above the rapids along which to haul the empty boats with the help of cut wooden rollers. We traveled upstream through periodic stretches of rapids to Pacu (= katabak in Wapishana) Falls, which has a sheer drop of about 5 m and necessitated hauling all supplies over a sheer rock outcropping that would be inundated when water levels are high. We proceeded up- stream through more rapids to just below Bamboo Falls, the largest falls on the Rewa River, which has a tiered set of sheer- drop falls totaling about 12 m. This old ?balata era? portage starts on the west bank at the end of a set of Class III rapids about 200 m below the Falls. After once again clearing the old portage and hauling our supplies, we made camp at the end of the portage above the Falls. We collected on an island in the Rewa River above Bamboo Falls, approximately 16 km southeast of the Kwitaro River confluence. Before reaching our next collec- tion point we had to portage around two sets of moderate rapids: Bush Cow Falls and Iguana Falls. At both portages we carried supplies over land and lined the empty boats through the rapids. It was then possible to travel upstream through calm water about 16 km to a point on the river with most direct access to several inselbergs between the Rewa and Kwitaro Rivers. On 17 February we began cutting a trail and collect- ing in forest in the direction of an inselberg about 6 km due west of the river; we reached the summit two days later. Near the summit the forest changed abruptly from high- canopy dense forest to more or less open low- canopy scrub forest. A king vulture roost and a jaguar sleeping in a tree were observed on the summit. Riparian collections were made along the Rewa River south of camp. A jaguar was observed on the riverbank and an abandoned porknocker?s (goldminer) camp was found on the river. We also collected along a newly cut line 0?2 km west of camp along the river and along the river to the north of camp. We then returned downstream to the confluence of the Rewa and Kwitaro Rivers, where we made camp on a sandbank. We collected on a sand le- vee to sample a successional gradient, in forest east of the river, and along the Rewa River south of the confluence. A parrot snake (Leptophis sp.) was observed very close (2 ft [0.6 m] away at eye level!) in the forest east of camp. We collected on a small mountain near camp immediately east of the river and along the Rewa River north of camp figure 8. Mollia glabrescens Benth.

We continued upstream to Kwitaro Landing, collect- ing in the forest along the trail to Shea 0?1 km west of Kwitaro Landing and along the river north and south of the landing. With the help of bullocks we returned to Shea Village where we could arrange transportation to Dadanawa, on to Lethem by truck, and back to Timehri by GAC sched- uled interior air service. triP 13: iWoKrama interna tional rainforeSt reSerVe 16 To 30 march 1997 (maP 6) This Iwokrama trip was the fifth expedition in a series to document the flora of the area. Scott Mori, a senior curator at the New York Botanical Garden, and his as- sistant, Scott Heald, provided additional expertise and enhanced collecting intensity. Scott Mori has completed a flora of Central French Guiana (Mori et al. 1997, 2002) and was able to provide important insights into the simi- larities and differences between the flora of French Guiana and of Iwokrama. Because only two weeks were available for this expedition we decided to concentrate on collect- ing in areas accessible from the road between Kurupukari and Annai, eliminating time- consuming travel by boat. In addition, a number of high- quality, diverse habitats are accessible from the road, in particular several areas in the Iwokrama Mountains at the end of trails to Mount Dan- iel and the gorge between the highest peaks in the moun- tains. These areas were found on previous expeditions to offer the highest levels of a- and b- diversity in the reserve and thus were thought to be the most productive areas for intensive collecting. Assistance was provided on this expedition by two workers with extensive experience in plant collecting, Romeo Williams from the Bartica area and Claudius Perry from Marunawa, South Rupununi Savanna. These two workers, with Scott Mori and me, expended a good deal of effort climbing trees to ensure that infrequently collected taxa were sampled. On this trip we made 272 collections of fertile taxa and many of these were from difficult to collect canopy trees, epiphytes, and lianas. In addition, Scott Mori and field assistants made 311 collections on this trip. The seven members of our team flew from Timehri to Annai via GAC and then traveled from Annai to Kurupu- kari by Land Cruiser. We began collecting along a transect beginning on the Kurupukari?Annai Road 5 km southwest of Kurupukari. The transect passes through terra firme mixed forest with greenheart reefs on brown sand over relatively flat terrain. Limited local relief accounts for the presence of Euterpe swamp forest in streambeds. We then traveled to Moco Moco II Creek 32 km southwest of Kurupukari on the Kurupukari?Annai Road where we rebuilt the camp and made several collections. We walked northeast along the road for 2 km to a transect that passes through poorly drained forest on white sand with Catostemma, Dimorphandra, and Eu- terpe, crosses two small creeks, and abruptly ascends a gorge and then a ridge to the summit of a granitic outlier of the Iwokrama Mountains (?Mount Daniel?). Collections were made on the summit in mixed forest. We returned to Mount Daniel in subsequent days to collect just below the summit, on upper slopes, and on lower slopes in a gorge with granite boulders and semi- disturbed vegetation. On 23 March we traveled from our camp at Moco Moco II Creek to the head of a transect leading to the Iwokrama Mountains, 45 km southwest of Kurupukari. The transect begins in Humiria scrub forest (n.v. ?muri?), passes through swamp forest on brown sand, crosses two creeks, and ends at a camp next to a stream at the foot of the mountains. We collected in the gorge separating the highest peaks of the Iwokrama Mountains, 0?3 km southeast of camp. This gorge has a high diversity of plants due to the combination of rheophytic, epipetric, semi- disturbed, and terra firme elements in the same area. The gorge appears to be substantially more mesic than other parts of the reserve and we observed a higher diversity of epiphytes. Finally, we collected along the transect leading from camp to the Kurupukari?Annai Road in mixed forest on brown sand with Mora, Carapa, and Socratea. We then packed our plants and supplies for transport to George- town via truck through Kurupukari and departed. triP 14: KuYuWini anD KaSSiKaitYu riVerS 27 aPril To 6 June 1997 (maP 8) A plant collecting expedition was made in far south- ern Guyana to the Kuyuwini and Kassikaityu Rivers. This expedition was conceived with the original goal of reach- ing and collecting in the Wassari Mountains on the Brazil- ian border. These mountains can be reached via the South Kassikaityu River and offer 1,000 m of elevational relief within several kilometers of the river. These mountains and the entire upper Kassikaityu are virtually unknown. They have been surveyed by the Boundary Commission 4 2 ? S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y MAP. 8.

N U M B E R 9 7 ? 4 3 and visited by Adrian Thompson, who collected a limited number of specimens on a trip that ascended the Kassika- ityu River, crossed the Wassari Mountains, and descended the Anau? River in Brazil to Manaus. The only person now living who has traveled in the area is Marifa, a Wai Wai who traversed the mountains to visit relatives on the Anau? River in Brazil. The middle and lower Kassika- ityu Rivers offer access to northern outliers of the Kamoa Mountains and, because the channel of the Kassikaityu River is more navigable than that of the Kamoa River, these mountains are best reached from the Kassikaityu River. Plant collecting in this area allows for a better un- derstanding of the floristic composition of the southern highlands of Guyana, the least well known of all floristic regions in Guyana. This trip was almost certainly the most arduous of all those I have carried out in two years of field work in Guyana. It was the rainy season and because we started from the Rupununi Savanna, we had to walk along two trails, 48 to 65 km long, to reach the Kassikaityu River. The effort expended in traveling also limited the collecting effort; although the trip was six weeks long, we had only a little more than two weeks for collecting. Travel from Karaudarnau on the Rupununi Savanna to the Kuyuwini River was facilitated by the use of two bullock carts to transport the 725 kg of food, fuel, and equipment at the start of the trip and the 318 kg of plants and equipment at the end. Travel from the Kuyuwini to the Kassikaityu River was more difficult because carts could not be used and everything had to be carried by people with back- packs or ?warishis.? Much of the trail was flooded and stream crossings were difficult. It took nearly two weeks to reach the Kassikaityu River since it took three trips each way to move the entire expedition forward. Shortage of rations at that point forced the party to abandon travel to the headwaters of the Kassikaityu River. Instead we re- turned downstream to the confluence of the Kassikaityu with the Essequibo River, downstream on the Essequibo River to its confluence with the Kuyuwini River, upstream on the Kuyuwini to the landing at the end of the trail from Karaudarnau, and from there, with the assistance of two bullock carts, to Karaudarnau and Aishalton. This expedition was staged from the Rupununi Sa- vanna with the idea of economizing by transporting goods and personnel by Bedford truck and GAC scheduled inte- rior air service rather than the more expensive alternative of using air charters. In retrospect, this expedition would have been only slightly more expensive if staged from Gunn?s Strip using air charters (approximately US$7,000 vs. the US$6,000 spent on this trip). The extra cost could easily be justified by the extra time allowed for collecting and the more thorough access to the Wassari and Kamoa mountains. As with all trips in southern Guyana, consid- erable effort was expended in cutting trails to gain access to mountainous areas for collecting. The time, effort, and extra personnel committed to cutting trail is justified by the greater habitat diversity and unique collections en- countered on these mountains. Romeo Williams from Bartica, Regis James from Aishalton, and Claudius Perry from Marunawa, skilled botanical field guides, provided valuable assistance on this trip. We also hired six Wai Wai workers who provided invaluable assistance. We made 813 collections of fertile taxa during this expedition. Our expedition team met in Dadanawa and traveled by Eddie Singh?s truck to Karaudarnau via Aishalton. As we made arrangements for transportation from the village, the first heavy rains of the rainy season arrived and we saw the first mass synchronous flight of winged termites (large species). We continued on across Parabara Savanna, where high creeks made for difficult stream crossings, and arrived at a landing on the Kuyuwini River at the termi- nus of a trail from Karaudarnau. We sorted rations, sup- plies, and equipment for transportation or to cache near the landing and with the help of four newly arrived Wai Wai workers, we crossed the Kuyuwini River to the farm of Charlie Mingle and collected along a trail that leads from there to the Kassikaityu River. Much of the north- ern portion of this trail crosses seasonally flooded forest on white or brown sand. Dominants include Catostemma, Oenocarpus, Euterpe, and Licania. Additional collections were made 0?2 km north of the landing on the trail to Karaudarnau. We arrived at Kassikaityu River camp on 19 May with all 10 members of the party and all supplies. Each day seven workers would return to the location of the previ- ous camp to transport supplies, while the remaining three workers remained at the current camp to collect. At the second camp, Honey Creek (1?58?N, 59?09?W), collections were made in flooded and terra firme forest, 0?3 km south of camp (Figure 10). A large fer- de- lance swimming into camp was dispatched. A puma was observed on the trail between Honey Creek Camp and Anteater Head Creek Camp and a large jaguar visited the camp in the daytime. A large branch fell on the unoccupied camp, damaging a tarp. At the third camp, at Anteater Head Creek, collec- tions were made in terra firme forest (Bertholettia, Sloanea, and Maximiliana dominant) near camp and 0?1 km to the south. A large tree fell on the camp in the night during a rain storm; only moderate injuries were sustained but the tarp was ruined. The workers were able to consume one 4 4 ? S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y white- lipped peccary each day as they crossed this trail in addition to rations brought from Georgetown. At the fourth camp, at Kassikaityu River, collections were made in forest 0?4 km north of the river in flooded and terra firme forest, 0?4 km along the river west of the landing at the terminus of the trail from the Kuyuwini River, and 0?3 km east of the landing. Habitat diversity in this area is increased by the presence of scrub forest on rock outcrop- pings near the trail. Mark Sos? extracted two botfly larvae from my head using Hevea latex. The carcass of a tapir regurgitated by an anaconda was observed in the river. On 22 May two young Wai Wai workers began the re- turn trip to Karaudarnau with plants and the remainder of the party traveled downstream in a large dugout, making camp on the Kassikaityu River 5 km north of an unnamed outlier of Kamoa Mountains (1?49?17?N, 58?44?06?W). We began cutting a line toward an outlier of the Kamoa Mountains and collected along this trail in heavy rain. Un- til 26 May the team collected on the summit and slopes of this mountain and in riparian vegetation 0?8 km east of the camp on the Kassikaityu River. We then traveled down- stream on the Kassikaityu River to its confluence with the Essequibo River, and downstream on the Essequibo River to its confluence with the Kuyuwini River. Monkey Jump, on the Essequibo River at 2?07?53?N, 58?18?27?W, is a small gold- mining site at the confluence of the Essequibo River with an unnamed creek used by the Wai Wai people to travel to New River; it is the only human habitation on the stretches of river traveled on this trip. We continued upstream on the Kuyuwini River, using low throttle to con- serve fuel, cutting through Astrocaryum and Inga blocking the channel, until we reached the landing at the end of the trail from Karaudarnau. We collected in riparian vegeta- tion along Kuyuwini River 0?5 km west of the landing. We traveled from the landing to a camp at the northern edge of Parabara Savanna (2?11?58?N, 59?22?14?W) and collected in the savanna and forest edge. We then traveled from Parabara Savanna to Karaudarnau, then to Aishalton (approximately 65 km total), and on to Dadanawa. Our final collections were made on Tautowan Mountain, 10 km east of Dadanawa on the road to Shea Village. From Dadanawa we traveled by Land Rover to Lethem, and by GAC scheduled interior service from Lethem to Timehri. Plants and equipment were left at Savanna Inn in Lethem for transportation to Georgetown by Eddie Singh?s Bed- ford truck. triP 15: W auKauYenGtiPu anD P aruima 29 June To 29 July 1997 (maP 3) A plant collecting expedition was made in the north- western Pakaraima Mountains of Guyana to Waukauy- engtipu and Paruima Village. Paruima is an excellent base of operations for expeditions because it is surrounded by tepuis in all directions that offer a diversity of plant com- munities. Two of these tepuis, Holitipu to the north (1,250 m) and Utshi/Great Falls of the Kamarang River to the south (1,100 m), have been visited by plant collectors in the past (Tim McDowell and Ben ter Welle). These two tepuis offer tepui scrub, savanna, and bog communities on their summits and premontane rainforests on their slopes. Waukauyengtipu, the eastern edge of which lies about 15 km due west of the village, rises to about 1,800 m and is one of the highest mountains in Guyana. The Amerindian community in Paruima, a branch of the Pem?n Venezuela, speak Arekuma. Their term ?Waukauyengtipu? means ?the mountain of the place of the butterfly.? There are only a few other areas in Guyana that offer comparable or higher elevations: Roraima, mountains such as Maringma south of Phillipai that are associated with the Roraima massif, Ayanganna, Wokomung, and Kopinang. Most of the tepuis in Guyana are of medium or low elevation, but the vegetation of tepui summits is determined more by edaphic factors related to flat sandstone substrates rather than elevation per se, so the occurrence of genuine figure 10.

N U M B E R 9 7 ? 4 5 high- elevation vegetation types, cloud forest in particular, is really quite limited. In Guyana it is restricted to the up- per slopes of some of the higher tepuis having northern or eastern exposures that are able to collect moisture from prevailing trade winds. As expected, cloud forest vegeta- tion was found on Waukauyengtipu on its upper slopes and at the summit near the eastern edge. Collections from these areas are expected to yield many new records for Guyana as well as many records of plants known pre- viously in Guyana only from Mount Roraima. No per- son in the living memory of the villagers has ascended Waukauyengtipu. An ascent of Waukauyengtipu is quite difficult for a number of reasons: (1) The trail from the village extends only about half the distance to the mountain, ending at Ararata scrub area; any further progress toward the mountain necessitates cutting trail. (2) There are no guides familiar with the terrain west of Ararata, meaning that the approach to and ascent of the mountain can be aided only by map, GPS, and compass. (3) Local people show a good deal of fear of the mountain and had to be convinced that it was safe. (4) The approach to the mountain from Ararata is over very difficult terrain, crossing steep ravines and ridges that are not indicated on the topographic map. (5) Most of the eastern face of the mountain is bordered by sheer 300 m cliffs; the only feasible route from Paruima is by a very steep cliff face more or less due west of Pa- ruima. (6) The final ascent of the mountain climbs 1,500 vertical m over 2.5 km. The time and effort involved in this ascent means that thorough collecting on the summit can be accomplished only by moving a camp to the sum- mit. Assistance was provided on this expedition by Tom Hollowell, data manager for the Smithsonian?s Biological Diversity of the Guiana Shield Program; Christopher Chin and Keith David, two biology students from the Univer- sity of Guyana; and Claudius Perry, a skilled Wapishana worker from Marunawa. We made 1,010 collections of fertile specimens on this expedition. After initial preparations a party of 10 left Paruima Village with sufficient rations, supplies, and equipment for the first week of the trip. We made camp and collected in premontane forest on brown sand with Mora gongrijppii, Sloanea, and Carapa near the camp. On 3 July our entire group moved to Ararata scrub area and established camp. We collected near the camp in scrub forest on white sand with Clusia, Pagamea, and Humiria. Over the next three days we collected in pre- montane forest on brown sand dominated by Micrandra, Eperua, and Cassia 0.2 to 0.5 km east of camp and in premontane forest 0.5 to 1.0 km east of camp. We then began cutting a line west from camp in the direction of Waukauyengtipu and made collections in dense forest on white sand and sandstone dominated by Dimorphandra, Eperua, and Dicymbe. As we continued cutting the line, we made collections in montane forests over white sand and sandstone. We cut across a number of steep ravines and reached the lower slopes of the tepui, then moved our camp to the base of Waukauyengtipu and made more collections near camp. As we cut a line to the summit of Waukauyengtipu, collecting on its middle and upper slopes, we crossed very steep terrain. The use of a rope was required over one pitch on a sandstone cliff. Canopy height was found to decrease toward the summit and bryophyte and epiphyte density to increase. Characteristic cloud forest elements were found beginning about 200 m below the summit, such as Sym- bolanthus, Weinmannia, Podocarpus, and Tachia. A large tropical rattlesnake (Crotalus durissus) was found and dis- patched on the summit. After moving supplies and equipment to the summit and dispatching workers to Paruima for resupply, we be- gan collecting on Waukauyengtipu on 12 July and con- tinued until 20 July (Figure 11). We collected in the cloud forest near the eastern edge of the mountain and cut a line to the top of a 300 m cliff on the eastern edge of the tepui to collect plants on the cliff face. A spectacular view was afforded from there of the entire upper Mazaruni valley, Roraima, Illutipu, and Great Falls of the Kamarang River, among others. After more cloud forest collections, we cut a line due west from camp near the eastern edge of Waukauy- engtipu toward a savanna 5 km west of camp. Progress was slowed by the difficulty of cutting through dense tepui scrub forest. The scrub forest varies in height from 4 m to about 15 m and is dominated by plants such as Bonnetia, Clusia, Brocchinia, Cybianthus, Schefflera, and Mollinedia. The workers who had gone to Paruima re- turned with supplies. As we continued cutting our line west across Wau- kauyengtipu, we reached and made collections in very dense tepui scrub forest, Euterpe swamp forest, and finally wet savanna at the end of the day on 17 July. The wet sa- vanna is a classic tepui bog community with Heliamphora, Brocchinia, Xyris, Drosera, Cladonia, Utricularia, and Paepalanthus. We also collected in bush islands adjacent to the savanna that had typical tepui scrub forest elements. The entire party then carried specimens and equipment from the camp on Waukauyengtipu to Ararata, where we observed a lek of the cotingid bird, Cock- of- the- Rock (Ru- picola rupicola). 4 6 ? S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y After a trip to Paruima we ascended and collected on two small tepuis: Konuktipu (690 m) 1.5 km south of Paruima and Warimatipu (880 m) 1.5 km north of the village. Before we prepared to leave we collected on the trail to Illubia Creek, a tributary of the Kamarang River about 3 km south of the village, and in Auratoi savanna 5 km north of the village, passing through a farm on the Pa- ruima River where a man was found who had been bit- ten by a fer- de- lance (Bothrops sp.) the previous night; the man died later that day. Our last collecting trip before departing for George- town was made along the Paruima River 0?1 km north of its confluence with Kamarang River at Paruima Village. Finally, we traveled by boat from Paruima to Ka- marang and by air from Kamarang to Georgetown, a cheaper alternative to chartering a plane from Paruima to Georgetown. triP 16: KWit aro anD reWa riVerS anD eaStern KanuKu mount ainS anD maKaraPan mount ain 5 sePTemBer To 6 ocToBer 1997 (maP 8) This plant collecting expedition was carried out on the Kwitaro and Rewa Rivers in southern Guyana. These two rivers give access, via the North and South Rupununi Savannas, to a large portion of the pristine, uninhabited, and poorly collected forest of southern Guyana. Previous work on these rivers in February 1997 (Trip 12) concen- trated on reaching the upper Rewa River through the ar- duous process of portaging dugout canoes and equipment around a series of falls. On this trip we concentrated on the lower Kwitaro and Rewa Rivers and the access they afford to the eastern Kanuku Mountains and Makara- pan Mountain. This one- way trip began at Shea Village in the South Rupununi and ended at Annai in the North Rupununi Savanna. This one- way plan allowed for sam- pling over a large latitudinal gradient. It also provide the opportunity to observe changes in floristic composition of the forest from southern Guyana, with its floristic af- finities to eastern Amazonia, to that of central Guyana, with its characteristic Chlorocardium and Mora forest. This expedition culminated a two- year collecting program in Guyana that, apart from three trips in the Pakaraima Mountains, concentrated on intensively collecting in for- ests from Iwokrama to the far southern border south of Gunn?s Strip. Assistance was provided on this expedition by Cynthia Watson, a biology student from the Univer- sity of Guyana, and two skilled plant collectors who have experience on numerous expeditions: Claudius Perry, a Wapishana worker from Marunawa, and Romeo Williams from Bartica. We made 874 collections of fertile taxa on this expedition; many of these were from difficult to col- lect canopy trees, epiphytes, and lianas using a tree climb- ing technique with climbing spikes and extendable clipper poles as described earlier. The team flew from Timehri to Lethem in a GAC scheduled Twin Otter, where we were met by Justin De- Freitas. We continued by Land Rover to Dadanawa, then to Shea Village where 770 kg of rations, fuel, and equip- ment had been sent a week in advance in Eddie Singh?s Bedford truck. We hired 13 bullocks and workers and made arrangements to transport our newly constructed dugout down- creek from the village to Kwitaro River (~32 km). We climbed out and collected on Shea Rock, a granite monolith 1 km north of the village (330 m elevation). Five workers transported the dugout down- creek to Kwitaro Landing to meet the main party, a task that required three figure 11. Heliamphora nutans Benth. (Sarraceniaceae) flowers, summit of Waukauyengtipu. N U M B E R 9 7 ? 4 7 days because of low water levels that necessitated drag- ging the boat over many obstacles. Between 10 and 12 September we collected in the forest near Kwitaro Landing, 0?1.5 km west of Kwitaro Landing on the trail to Shea Village, and along the Kwitaro River 0?2 km north of the Landing. The entire party of 11 people then traveled in three dugouts with all supplies and equip- ment down the Kwitaro River, lining the boats through a stretch of rapids several kilometers long immediately below the landing. We camped at the farm of a Wapishana man from Shea (Harold Paul); this is the only human habitation on either the Kwitaro or Rewa River. Continuing down- stream we made camp at a point on the river due east of the Kanuku Mountains and began cutting a line due west from camp toward the Kanuku Mountains. We continued cutting line and collecting along the line in seasonally flooded forest until we reached the lower slopes of an unnamed mountain (summit at 3?11?22?N, 58?51?18?W). Ascending to the 560 m summit of this unnamed mountain we collected near its summit, which had inselberg scrub vegetation on granite outcrops with high epiphyte diversity. After we collected on the summit and upper slopes of this mountain, we contin- ued to collected along the Kwitaro River 0?5 m north and 0?5 m south of camp. On 19 September we traveled down the Kwitaro River and up the Rewa River and occupied an old camp (February 1997) on the west bank of the Rewa River im- mediately below the Great Falls. We collected along the Rewa River near the Great Falls and downstream 0?5 km north of camp below the Falls. We then traveled down- stream to the confluence of the Rewa and Kwitaro Riv- ers. Four workers from Shea began a return trip to Shea, paddling and poling in one of the three dugouts. Our re- duced party of seven traveled in two dugouts down most of the length of the Rewa River, making camp at a bend in the river about 10 km south of the confluence with the Rupununi River. The lower Rewa River is a classic low- land meandering river with healthy populations of black caymans, Podocnemis river turtles, iguanas, arapaima and other game fish species, and other sensitive species that are threatened elsewhere. We cut a line from the river 1 km due south to an oxbow lake and collected in and around a Mora forest. We also collected along the Rewa River between camp and the confluence of the Rewa with the Rupununi River. We then traveled down the Rewa River and up the Rupu- nuni River several kilometers to Rewa Village, where we visited with tuchau (Matthew Alvin) and recruited several Macushi workers for collecting on Makarapan Moun- tain. We continued upstream on the Rupununi River to Kwattamang Landing (5 km from Annai). Our progress was slowed on the Rupununi River by low water levels and emergency repairs to the hull of the dugout broken by striking a sunken tree. At Kwattamang Landing we were joined by an addi- tional worker from Annai. We traveled to a point on the river due south of Makarapan Mountain and then carried our supplies 8 km north from the river to the base of the southern face of Makarapan Mountain. Camp was made next to a small creek in forest semi- disturbed by swidden fallow agriculture. On 29 September we began cutting a line to the top of Makarapan Mountain, reaching the southern false sum- mit. The false summit is a granite inselberg dominated by scrub elements such as Clusia, Erythroxylum, and epi- petric bromeliads. That day and the next we collected on the southern false summit, on the lower slopes, and near camp. Finally we ascended to collect on the true summit, which also has inselberg vegetation and, in addition, epi- phytic elements more characteristic of cloud forest, such as Utricularia, bryophytes, and a number of orchid and bromeliad species. During the next few days we collected in forest, savanna, and scrub 0?2 km south of camp at the base of the mountain while continuing to collect on the middle slopes and upper slopes below the southern false summit. We headed out on 4 October carrying the plants and equipment to Rupununi River and traveling up the Ru- pununi River to Kwattamang Landing and from there to Annai, where we flew via GAC scheduled Twin Otter service to Timehri. Plants and equipment were left in An- nai for transportation by Eddie Singh?s Bedford truck to Georgetown. triP 17: acarai mount ainS?SiPu riVer 18 augusT To 18 sePTemBer 1998 (maP 9) This trip up the Sipu River to the Acarai Mountains began at Gunn?s Strip (Figure 12). The expedition col- lected in secondary forest and in semi- open land on gray sandy clay with Oenocarpus, Macrolobium, and Licania. After a few days of preparation we moved along the Sipu River toward the Acarai Mountains, collecting in dense seasonally flooded forest on gray sand and finding Aspido- sperma, Euterpe, Isertia, Oenocarpus, Duguetia, Eperua, and Clusia in various locations. Reaching the lower slopes of the Acarai Mountains 4 km south of the Sipu River, the team ascended to the summit of an unnamed peak 6 km south of the river. The lower slopes of the mountain were 4 8 ?

At the summit the dense forest on brown sand included gran- ite boulders, and the species Sloanea, Palicourea, Oeno- carpus, and Clusia were apparent. On 1 September the expedition reached the summit of the highest peak in the central Acarai Mountains 10 km south of the Sipu River and established camp at the base of this peak. On the summit the team found dense forest on brown sand and granite boulders with Catostemma, Oenocarpus, and Bactris (Figure 13). Another location on the summit was dominated by scrub forest on peat and granite with Erythroxylum, Clusia, and Myrtaceae. The area near this camp and around a creek at the base of the high peak was dominated by dense forest on brown sand and granite boulders, with Eperua, Parkia, and Sloanea. Descending to a location 4 km south of the Sipu River, the expedition established a new camp in dense forest on brown sand. Common species in this forest included Epe- rua, Sloanea, Oenocarpus, Pouteria, Bactris, Symphonia, Bertholettia, and Rinorea. Traveling 0?5 km east of camp, the team made collections in dense seasonally flooded for- est on gray sand, with Eperua, Aspidosperma and Euterpe. Farther to the east the area along the Sipu River included riparian vegetation and dense forest on poorly drained gray sandy clay, with Symphonia, Euterpe, and Eperua. To the west 0?3 km from camp, the river banks were cov- ered with dense forest on poorly drained gray sandy clay, with Eperua, Aparisthmium, and Euterpe. Finally, the expedition returned to Gunn?s Strip. The savanna surrounding the airstrip 2 km west of the vil- lage and the Essequibo River is located on poorly drained white sandy clay and supports Brysonima, Trachypogon, and Tibouchina. triP 18: W aSSari mountainS, uPPer taKutu?uPPer eSSequibo reGion (reGion 9) 18 augusT To 28 sePTemBer 1999 (maP 9) A plant collecting expedition was made in southern Guyana into the Wassari Mountains in the headwaters of the South Kassikaityu River on the Brazilian border. This trip was designed as part of a series to sample vegetation of the highest elevations in southern Guyana. Collecting at higher elevations in this area is important for several reasons: (1) The difficulty of access in southern Guyana has restricted previous collectors to areas along rivers. (2) High- elevation collecting is necessary to test the extent to which vegetation changes with elevation in this area and to test the prevalent hypothesis that the mountains of south- ern Guyana are not high enough to have genuinely montane habitats. (3) Collecting in the highest elevational gradient in the area is likely to result in sampling more habitats, whether for elevational, edaphic, or other considerations, figure 13.

S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y and allows for collecting more species than collecting done exclusively at lower elevations. At 1,135 m the unnamed mountain ascended in this expedition is the highest eleva- tion in Guyana south of Kowatipu, a sandstone tepui in the southern Pakaraima Mountains (1,295 m). The other areas in southern Guyana with elevations near or above 1,000 m include the Iwokrama Mountains, Makarapan Mountain, Acarai Mountains, Kanuku Mountains, Kamoa Mountains (see previous trip reports), and an isolated mas- sif of the Acarai Mountains at the headwaters of the Muri River in the New River Triangle (where access is prohibited because of permit problems). The Wassari Mountains were an especially important focus for plant collecting. Results of the expedition would add to the data set of the moun- tains of southern Guyana, which are remarkably uniform regarding their abiotic environmental conditions (granitic geology, rainfall, temperature, elevation, etc.), and would allow for the attribution of observed floristic differences to historical rather than ecological factors. Only one previous visit has been made to the Was- sari Mountains. In 1970 Adrian Thompson skirted the southern and western parts of the area while making a traverse from the Kassikaityu River just above the landing of the trail from Kuyuwini River, across and up the Kamoa River, across to the Anau? River in Brazil, and from there to Manaus in Brazil. Several Brazilian gold miners were escorted up the South Kassikaityu River from Gunn?s Strip by two Wai Wai men in June 1999, but they had to turn back a good distance from the Wassari Mountains because one of the Wai Wai guides died from malaria. The area has probably not been inhabited since the 1930s when the last of the Atorad Amerindians disappeared from this area. Access to the Wassari Mountains is best gained through the Wai Wai Amerindian village of Gunn?s Strip on the upper Essequibo River, the only human habitation in the forests of southern Guyana, an expanse of some 7 mil- lion hectares. An attempt to reach the Wassari Mountains in July 1996 failed because the official 1:1,000,000 map of Guyana that was consulted in planning the expedition incorrectly places the mountains between the Kuyuwini and Kassikaityu Rivers (see previous trip reports). Subse- quently, in May 1997 another attempt to reach the Was- sari Mountains from the Rupununi Savanna failed due to shortage of rations and the time consumed in traversing the trail from the Kuyuwini River to the Kassikaityu River. This expedition began at Gunn?s Strip, which, al- though nearly 200 km by river from the Wassari Moun- tains, is still closer than the Rupununi Savanna and provided direct river access to the Kassikaityu River from its confluence with the Essequibo River. The German magazine Geo wanted to feature a bo- tanical expedition for their January 2000 issue and joined this expedition. Henry Tschinkel, former director of the Iwokrama International Rainforest Programme in Guyana, acted as liaison for the Geo group represented by the writer Johanna Wieland, photographer Mattias Klum, and his as- sistant ?la H?gberg. Assistance on this expedition was pro- vided by Claudius Perry of Marunawa, Romeo Williams of the Bartica area, Benny Cheong of Orinduik, and six work- ers from Gunn?s Strip: Wachana Yaymochi, Yuphon Maru- wanaru, Aaron Maruwanaru, Kayanama Ayaw, Thomas Andrew, and Bemner Sos?. We made 1,008 collections of fertile specimens on this expedition; many were from dif- ficult to collect canopy trees, epiphytes, and lianas. On 18 August the team congregated in Gunn?s Strip. Permission was obtained and arrangements were made to hire workers, rent three dugout canoes, and purchase food supplies. The entire party of 14 left three days later and traveled north on the Essequibo River to its confluence with the Kassikaityu River (km 38.2). We then traveled up- stream on the Kassikaityu River, making camps at km 71.2 and km 137.5 and on the South Kassikaityu River at km 184.5. High water levels and frequent rain during the four days of travel up the river were due to the late rainy season. Continuing up the South Kassikaityu River, we made camp at the point giving most direct access to the high- est point in the Wassari Mountains (km 192.8). Along the South Kassikaityu River we had to repeatedly use a chain- saw to clear the channel; at times the river narrowed to about 10 m in flood stage at the highest point. Beginning at the river and heading toward the Wassari Mountains, we cut a transect and made collections in flooded forest on gray sandy clay with abundant Euterpe and Mauritiela and in flooded swamp and liana forest along a creek be- tween the two northern foothills of the Wassari Moun- tains. Camp was moved to the base of the mountains on 28 August and the next day we began cutting the line up and over an 840 m ridge south of camp, collecting on the ridge summit. Several hundred meters south of camp we discovered a one- or two- year- old trail with east?west heading, possibly coming from Brazil. Our cut trail continued down the southern side of the 840 m ridge, reaching a creek at the base immediately north of the massif of the highest peak in the Wassari Mountains. We collected on the ridge summit, in a large treefall immediately below the summit, and in a ravine below the ridge. A jaguar was heard growling close to the collectors. Moving our camp over the ridge to the creek, we cut over the first and second summits to reach the highest peak in the Wassari Mountains. Collections were N U M B E R 9 7 ? 5 1 made along the way (Figure 14): near camp in a flash- flood- prone bamboo (Guadua) forest; 0?0.5 km south of camp in dense forest with rock outcroppings; on middle slopes of the first summit 0.5?1.0 km south of camp; and on the summit of the 1,135 m peak in inselberg scrub forest on granite and Sphagnum. Soils in the area of the middle slopes were a deep red clay loam not seen in other areas. A large buttressed Ficus was the dominant emer- gent in this area. On the summit, Lauraceae (Rhodoste- monodaphne scandens, e.g.), Clusiaceae, and Myrtaceae were dominant, with abundant epiphytes maintained by frequent cloud contact. At the summit we paused to con- sult with members of the Geo team about the story and to take photographs. On 7 September we began cutting a trail east of camp to an unnamed 975 m mountain with a high- canopy high- diversity forest with abundant Bertholettia. Apodanthes casearieae Poit. (Rafflesiaceae) was common as well as Casearia on the upper slopes of this mountain. A jaguar was sighted along the trail. This peak?s summit is domi- nated by inselberg scrub forest and offers excellent views of the Acarai Mountains, Wassari Mountains, and into Brazil. We continued collecting for several more days on the summit of the 1,135 m peak and between the peak and camp. The first summit between camp and the 1,135 m peak is dominated by inselberg scrub forest with abundant Guadua, Erythroxylum, Sphagnum, and Myrtaceae. Epi- phytes are not as common on the smaller peak, perhaps due to less frequent cloud contact. Making our last collections near camp in a flash- flood- prone forest with Guadua, Inga, Socratea, and Cecropia dominant, we carried our equipment to a new camp on the South Kassikaityu River. From this camp we collected 0?0.8 km south of the South Kassikaityu River on a transect start- ing at 1?38?56.8?N 59?14?58.7?W and heading toward the Wassari Mountains and along the South Kassikaityu River 0?6 km northeast of camp and 0?2 km southwest of camp. On 22 September we traveled by dugout canoe to a previous camp (22 August). Heavy rains and rising river levels made for efficient travel. The Wai Wai opted for a fishing day to take advantage of active feeding by Haymara (Hoplyas macrophthalmus) in response to rising water levels. We continued by dugout to Gunn?s Strip, stopping to collect on an island above Baboon (Biloku) Rapids (shipu- kashi = howler monkey in Wai Wai). Finally, we weighed and packed plants, supplies, and equipment, carried goods from the village to the airstrip, and flew by twin engine Islander from Gunn?s Strip to Ogle the next day. triP 19: mount a YanGanna, Potaro?SiParuni reGion (reGion 8) 30 may To 10 July 2001 (maP 10) A plant- collecting expedition was made to the summit of Mount Ayanganna from an unexplored route ascend- ing the east face. Mount Ayanganna (2,040 m elevation) is the highest mountain wholly within Guyana; it is a tepui, or flat- topped mountain, and a member of the Roraima sandstone formation. Although Mount Ayanganna may be the outstanding topographic feature of Guyana (along with Mount Roraima), it has received little attention from previous plant collectors because it is difficult to access. Previous collectors include Bassett Maguire, Bruce Hoff- man, Terry Henkel, John Pipoly, and Steve Tillett. The first documented ascent was by Adrian Thompson on Indepen- dence Day (26 May) in 1966. All previous expeditions have been attempted from the western approach because Akawaio Amerindian guides figure 14.

The western approach requires air charters to Imbaima- dai, boat travel to Chi Chi Falls upstream on the Maza- runi River from Imbaimadai, walking from Chi Chi Falls to Chinowieng Village (the last human habitation on the west slope in a savanna inclusion), and walking approxi- mately 40 km from Chinowieng to Mount Ayanganna by passing northeast of the summit on the lower escarpment, gaining the ridge that ascends to the summit escarpment, and climbing to the summit from there. The eastern face and the Potaro River drainage are uninhabited from the summit down to Chinapau Village and Kaieteur Falls. Ac- cess from Chinapau would be impossible because the Pa- tamona Amerindians who live there do not travel above the falls upstream on the Potaro River (the main falls, Kai- eteur, is immediately downstream from Chinapau). Before this expedition, the route to the summit estab- lished by Isaac Jerry (an Akawaio Amerindian) and Adrian Thompson was from Chinowieng. That route has been used by all other parties, including members of the Guyana Defense Force who make annual ascents on Independence Day. Like most tepuis, Mount Ayanganna consists of tiered escarpments, which are often quite sheer, separated by flat or gently sloping plateaus. The east face consists of four separate escarpments, whereas the west face has only the summit escarpment and the three lower escarpments com- bined into one steep, but passable, escarpment. A primitive white sand airstrip was cleared by dia- mond miners on the upper Potaro River about 15 km southeast of the summit during the 1980s. This airstrip has since been abandoned but a group of Brazilian dia- mond miners have built an improved laterite airstrip lower on the Potaro River about 20 km southeast of the summit. We chose a route from the airstrip because, al- though pioneering this new route would involve extensive line cutting, the airstrip is much closer than the approach through Imbaimadai, Chi Chi, and Chinowieng. This eastern approach was also expected to yield many unique collections. The eastern face directly intercepts the north- east trade winds from the Atlantic and may thus have the highest rainfall and most wet, high- elevation cloud forest and scrub habitats on its slopes, areas that often harbor unusual endemic taxa. We made 1,021 plant collections on this expedition. Collections were made thoroughly at all elevations, mak- ing this a representative, if not a complete, collection of the flora (representing the month of the year visited) of a previously undocumented and unexplored face of this important tepui. Poorly known canopy tree, epiphytes, and lianas were collected by extensive tree climbing using tree- climbing grimpettes and extendible aluminum clipper poles, augmenting the collections? value. Supplies for the trip included 1,200 lb (~550 kg) of rations packed in five- gallon buckets, including 135 kg of cassava farine; 550 kg of equipment and supplies, includ- ing 70 kg of newspaper and 15 gallons (~57 L) of alco- hol for collecting plants; 12 gallons (~45 L) of gasoline and an 84 lb (38 kg) Yamaha 15 hp engine for travel on the Potaro River; a two- way radio, antenna, solar pan- els, and battery; and packframes, cutlasses (machetes), sleeping bags, warm clothes, trade items, and tents for the Patamona Amerindian workers. Romeo Williams and Claudius Perry (experienced Arawak and Wapishana parataxonomists, respectively), Josh Kelly and Erin Tripp (undergraduate students from the University of North Carolina at Asheville), and the I flew from Ogle Airport in Georgetown to Ayanganna. A flight diverted to Orinduik picked up four Patamona Amerindian workers: Leonard Williams, Colin Albin, Pedro Joseph, and Edward Joseph. The entire party moved rations and equipment from the airstrip about 1 km west to a landing on the Potaro River where a provisional camp was made for the night. As rations and equipment moved upstream from the new airstrip to the old Ayanganna airstrip on an aluminum boat rented from Brazilian miners, the full complement of the expedition party formed as Charles and Milton Jo- seph and Moses Williams (Patamona Amerindians) joined the group after walking overland from Orinduik on the Brazilian border. The expedition party moved up the river with the last load to Terry Henkel?s (mycologist and for- mer BDG collector) camp on the Potaro River. All river travel above the old airstrip was by paddling in a dug- out canoe, because the dugout was too small to accept the outboard engine and the Brazilian aluminum boat was no longer available. Expedition supplies were transported upstream on ?whitewater river,? an unnamed tributary of the Potaro that runs parallel to the eastern face of Mount Ayanganna. These supplies were to be stored at the site of the future ?whitewater camp.? Meanwhile, collections were made in the forest at the base of a laterite ridge along an affluent of the Potaro River 2 km south of Henkel?s camp. From this camp a line was cut along a direct compass heading to the base of the toe slope of the first escarpment where more collections were made. Considerable diversity is present in this area, resulting from a mosaic of terra firme forest on laterite ridges with seasonally flooded forest on white sand. The expedition party moved along the cut line and then bushwacked east through forest to make camp at ?whitewater camp? with the cache. 5 4 ? S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y Six inches (152 mm) of rainfall (measured by a rain gauge in Henkel?s camp) on the night of 5 June caused the river to rise 5 m or more. We were forced to evacuate whitewater camp to an impromptu camp on the first later- ite ridge about 500 m west of the river. Ropes were needed to assist evacuation through flowing water in the flooded channel of the river and the move took three days. We resumed collecting on a plateau edge above and on the summit of the first of four escarpments. On the top of the first summit (1,008 m elevation) soils changed from lateritic clay to white sand and gray sandy clay. The physi- ognomy of the forest of the first plateau differed from that of the base of the massif by having a lower (~15 vs. 20?30 m), non- stratified canopy with epiphytes at all levels and an abundant shrub and herb layer. Legumes were much less abundant and Clusiaceae, Myrsinaceae, Euphorbia- ceae, and Melastomataceae became more abundant. In- undated forest dominates due to limited slope and because the sandstone bedrock is close to soil surface. The camp was moved to a position along the creek about 1 km from the summit of the first escarpment. Col- lections were made near camp and on plateaus 1?2 km north of camp as the team continuously cut a line toward Chinowieng summit. Camp was moved to the top of a wa- terfall on an affluent of whitewater river at the edge of the first plateau and was then moved immediately below the second escarpment. Collecting there found unique montane elements such as Hedyosmum (Chloranthaceae). Dense for- est on the second escarpment opens into broken- canopy (~10?12 m) scrub forest on poorly drained white sand and sandstone on a plateau between the second and third es- carpments, turning into dense cloud forest on the plateau above the second escarpment and on the third escarpment, and finally becoming tepui scrub and cloud forest with high- elevation endemics such as Podocarpus, Weinmannia, and Mutisieae?Asteraceae on the plateau above the third escarpment. On the fifth day the cut line reached an inter- section with a trail from the west slope to Chinowieng, high on the summit escarpment, where collections were made in dense scrub forest with low (5 m) canopy. Camp moved to the base of the fourth summit escarpment at 1,545 m. Edward Joseph?s femur was badly bruised by a rock dislodged from an unstable slope during descent and he was carried into camp in a warishi (Amerindian backpack made from Ischnosiphon fibers). While five members of the party moved to a new camp at the summit, the remaining members stayed in the lower camp to provide logistical sup- port and remain with Edward Joseph. The five at the sum- mit made collections near the camp in sloping tepui bog dominated by Brocchinia, Rapateaceae, and Cyperaceae; on the summit proper, a rock outcropping with epipetric and scrub vegetation; and on the east face near the edge of the summit plateau in tepui scrub forest. They then re- turned to the camp at the base of the summit escarpment and made more collections near the lower camp. The expedition party moved to a camp at the top of a waterfall at the base of the second escarpment and made collections in nearby forest. Heavy rainfall that night de- stroyed the tarp over the hammocks, forcing evacuation to the camp at the base of the first escarpment. In forest near this camp the restricted endemic and monotypic Ma- guireanthus ayangannae (Melastomataceae) was collected along the stream on a fallen log. Expedition members made additional collections in the forest 0.2?1 km south of camp along the trail to Henkel?s camp. I encountered? and dispatched?a poisonous parrot snake (Bothriopsis bilineata) in a Micrandra tree (Euphorbiaceae). On 2 July the expedition party moved to Terry Hen- kel?s camp along the Potaro River. Collections were made near camp and in riparian vegetation along the Potaro River 0?2 km east and 0?2 km west of camp. We then moved to the old Ayanganna airstrip and from there to the new Ayanganna airstrip by aluminum boat with an out- board engine rented from Brazilian miners, making collec- tions in both locations. Departure was complicated when the pilot of the single Cessna 206 reported malfunction and loss of power, say- ing that only 400 lb (181 kg) of the anticipated 700 lb (317 kg) could be transported. Moreover, intense rain pre- vented diversion to Orinduik to return the Patamona work- ers to their home. Romeo and I boarded the aircraft with the plant collections; in blinding rain, the airplane barely cleared the trees at the end of the runway and was very slow to gain elevation needed to climb above the summit mas- sif of Mount Ayanganna. The remaining expedition party made provisional camp at the airstrip. Once in Georgetown I urged the air charter company to evacuate the remaining personnel and equipment, which they did the next day. The Britten Norman (BN) Islander diverted twice to return the six Patamona workers to Orinduik but was forced by dark- ness to land at Timehri Airport with the 300 lb (136 kg) of equipment before continuing on to Ogle the next morning. triP 20: mount WoKomunG, Potaro?SiParuni reGion (reGion 8) 15 June To 23 July 2003 (maP 10) Mount Wokomung yielded 1,118 collections of plants over a five- and- a- half- week period in the summer of 2003. N U M B E R 9 7 ? 5 5 This tepui (flat- topped, sheer- walled, sandstone mountain of the Guiana Highlands) attracted attention for several reasons: (1) Its elevation, at 1,660 m is the second- highest mountain after Mount Ayanganna (2,080 m) wholly within Guyana. (2) It lies at the southern end of a chain of tepuis that begins with Kamakusa (1,646 m) and Ka- ranang (1,516 m) at the northern edge of the escarpment of the Pakaraima Mountains and passes south over Mount Ayanganna to Mount Wokomung, a distance of 120 km. (3) It has a northeast aspect, which, combined with its high elevation, directly intercepts moisture- laden trade winds from the Atlantic and creates genuine montane wet cloud forests, a habitat that occurs only in restricted ar- eas in Guyana. (4) It forms, with Mount Ayanganna, the high- elevation headwaters of the Potaro River, the river that forms Kaieteur Falls some 60 km downstream. Kai- eteur National Park is the cornerstone of Guyana?s Na- tional Protected Areas System (Figure 15). Proposals to expand Kaieteur National Park have encompassed both Mount Wokomung and Mount Ayanganna, but, before my 2001 expedition to the summit of Mount Ayanganna from the eastern face, no botanical data were available for the higher elevations of the entire upper Potaro wa- tershed. Furthermore, although environmental threats to the Park from mining and other activities along the Potaro River below the Falls are well known, diamond mining by Brazilians and Guyanese in and adjacent to the Potaro River above the Falls has increased due to the recent con- struction of a laterite airstrip that provides access to this area. Documenting the botanical diversity of this region as baseline data before additional disturbance is essential for adequate monitoring and land use planning. The rejec- tion of Kaieteur National Park for inclusion in the World Heritage List (IUCN, 2001) was based largely on the lack of documented diversity and the small size of the park (42 km2) as it currently exists. Data from the Wokomung ex- pedition can help to ameliorate this shortcoming for any future conservation proposals in the area. Recent construction of a laterite airstrip in the Upper Potaro by Brazilians has made expeditions to the Woko- mung/Ayanganna area feasible from an eastern approach. Mining operations provide the only infrastructure in this area because the upper Potaro River has no permanent hu- man habitations above the Patamona Amerindian village of Chinapau, which is immediately adjacent to Kaieteur National Park. Earlier expeditions to Mount Wokomung were either from the village of Kopinang several kilome- ters south of Mount Wokomung (Brian Boom, New York Botanical Garden, 1987 and 1989) or from the upper Ireng River to the west (Terry Henkel, Smithsonian Institution, 1993). A white sand airstrip several kilometers upstream of the new airstrip functioned for several years in the 1980s, but was never safe for landings or takeoffs with anything other than very light payloads. My 2001 expedition took advantage of the eastern approach to Mount Ayanganna and yielded four species and one genus new to science in addition to many other valuable collections. As on Mount Ayanganna, once the difficulty of having to cut new trail from the river to the summit is overcome, the eastern ap- proach offers the advantage of providing access to those parts of the massif with the largest surface areas above the first escarpment. These extensive genuinely montane habitats?the principal target of this expedition?are not often encountered in Guyana and are expected to har- bor a high diversity of unique plant species. Given these considerations, the overall plan of the expedition was figure 15. Kaieteur Falls from Johnson?s View. 5 6 ? S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y straightforward: move from the New Ayanganna airstrip 24 km downstream on the Potaro River to a point that provides the most direct access to Mount Wokomung and then cut trail and collect along that trail to the summits of each of the three highest parts of the Mount Wokomung massif, returning by the same route. Preparations for the Wokomung expedition began in earnest in March 2003 with the submission of a proposal to the Guyana Environmental Protection Agency for per- mission to carry out the work. I arrived in Guyana on 7 June 2003 with Josh Kelly and Erin Tripp (University of North Carolina at Asheville alumni and returning mem- bers of the 2001 Ayanganna expedition), and Stephen Stern (UNC- Asheville student). We spent one week preparing for the expedition, assembling a manifest that totaled 1,800 kg: 635 kg of rations (including 90 kg farine and 60 kg salt fish) and 400 kg of equipment, including two outboard engines, 150 kg gasoline, and 635 kg of personnel and gear. On 15 June we flew from Ogle airstrip to the New Ayanganna airstrip with all supplies and equipment in two Islanders and one Cessna 206 airplane. We were met at the airstrip by five Patamona Amerindians from the upper Ireng village of Kaibarupai: Leonard and Moses Williams, Colin Albin, and Charles and Linus Joseph; all but Linus Joseph participated in the 2001 Ayanganna expedition. The group was joined later in the week by Romeo Wil- liams and Claudius Perry, long- term Guyanese associates and parataxonomists who have accompanied many other scientific expeditions, and Diana Gittens, a student from the University of Guyana. All supplies and equipment were carried from the airstrip about 500 m to the Bastos mining camp at the lower landing on the Potaro River and a wooden boat was rented for the length of the expedition. While supplies and equipment were moved several kilometers downstream to a camp at Malek Falls on the Potaro River, collections were made at the airstrip. The entire party moved to the new camp and collections were made in disturbed forest near Malek Falls while supplies and the workers were shuttled down the Potaro River. As remaining personnel, supplies, and equipment trav- eled downstream from Malek Falls by boat, the stern wave of a passing boat transporting miners upstream flooded our bow, causing it to sink with the chain saw, tree climb- ing spikes, outboard, machetes, and aluminum clipper poles. All other supplies and equipment floated because they were secured in either plastic buckets or heavy plastic bags. Members of the expedition party swam to shore, col- lecting flotsam in the process, establishing once again and yet in a novel fashion that everything on a plant- collecting expedition, including the botanists, is fully immersible. The miners transported the expedition party and equip- ment downstream to the river camp, where a provisional camp was made. Radio communication was established with George- town by felling trees to erect the antenna and to allow for solar charging of the radio battery. The BDG had extra equipment in Georgetown so a radio message was sent to Terry Henkel, mycologist from Humboldt State University, California, to bring extra clipper poles and tree climbing spikes when he flew in the next day. Romeo Williams re- turned to the site of the sunken boat to retrieve the remain- ing expedition equipment left onshore, delivered the goods to the river camp, and left for the New Ayanganna air- strip to secure the services of a compressor, a floating river dredge, and a diver to retrieve the lost boat and equipment. He returned two days later with the tree climbing spikes, boat, and engine, but not the chain saw or clipper poles. Collections were made around camp, principally epi- phytes from trees felled for the radio, as David Clarke and the Patamona Amerindians began cutting a line toward the base of the first escarpment of Mount Wokomung. The next day Romeo Williams led the cutting party as the re- mainder of the expedition party hauled material to the end of the trail cut the previous day. Moving supplies contin- ued to the site of a future camp at the base of the first of four escarpments. Plants were collected in the forest mid- way between the river and the mountain. Noting that the river level had dropped since the boat overturned, Romeo and several of the party returned up- stream to search for the clipper poles. They were unsuccess- ful, but returned with poles brought in by Terry Henkel. On the 23 June the entire party moved camp to the base of Mount Wokomung, leaving a cache of specimens, rations, radio, and other equipment with the small land dredge operation on the opposite side of the river. The party made collections in the forest surrounding camp in both seasonally flooded and terra firme forest on steep lat- eritic slopes. Further collections were made on northeast facing slopes of the first escarpment in naturally disturbed forest on steep lateritic slopes. As equipment and supplies were moved from the base of the first escarpment to a new camp on the plateau, a fixed line was necessary to help people up the slope im- mediately below the summit of the escarpment. The flat poorly drained terrain made finding a suitable stream for a water supply difficult in this area. Collections were made in semi- open, single- tiered canopy forest near camp and at the edge of the plateau, as line cutting proceeded to the summit of the easternmost pinnacle on the massif. N U M B E R 9 7 ? 5 7 Line cutting, accompanied by collecting, proceeded to- ward the highest summit of the Mount Wokomung massif (Figure 16). The summit was reached on 5 July and collec- tions were made in a tepui bog. The line cutting then began from a position below Little Ayanganna toward the sum- mit of Mount Wokomung proper, the westernmost summit of the massif, via the second and third of four escarpments, 1.5 km northeast and 1 km northeast of Mount Woko- mung. On 8 July we reached 1,490 m and camp was moved to a position immediately below the summit. The expedi- tion party continued to collect on the summit, near camp, and around the previous camps as the party returned along the line. Final collections were made in forest near the pre- vious Potaro River camp and along the river 0?2 km north of camp and 0?10 km south of camp. After sending collections, supplies, and equipment up- stream on the Potaro River, the entire expedition left the Potaro River camp in two boats, portaged around two falls, including Malek Falls, and arrived at the landing of the New Ayanganna airstrip. All collections, supplies, and equipment were moved from the landing and base camp to the airstrip. Finally, all plant collections, personnel, and equipment left for Ogle airport in a Cessna 206 and an Islander. triP 21: central Suriname nature reSerVe 22 feBruary To 10 march 2004 (maP 11) Collecting on this trip began along the Coppename River at Bureau Waterkracht Werken Camp, 500 m south of Tonckens Falls, and continued on to Tonckens Falls. From there we moved to collect along the Rechter Cop- pename River, near Bolletrie Falls, and along an unnamed tributary of the Rechter Coppename River. The headwaters of the Rechter Coppename have their origin on the Tafel- berg, the easternmost tepui in the Guiana Shield, which allows for representation of an ecological and elevational gradient otherwise not represented in Suriname. Classic examples of flooded forest, aquatic vegetation associ- ated with periodically inundated rocks, herbaceous com- munities found on sandbars, and terra firme forest were observed. Although many of the plant species occur in other areas of the Guiana Shield, the assemblage of spe- cies that exists in the Rechter Coppename is unique. The river was found to be impressive in both basic botany and plant conservation, as described below. Terra firme forest in the Rechter Coppename was found close to the river, always less than 50 m and frequently only 10 m from the river. Typical examples of herbaceous plants, understory trees, palms, midstory trees, canopy trees, and canopy emergents were represented. Diversity at the species level in each of these major groups of plants was found to be moderately high. Flooded forest occupied a narrow band and was often on steep banks near the river. Typical gen- era such as Psidium and various other Myrtaceae were represented. The flooded forest, especially when subjected to siltation as occurred on river banks with low relief, had a non- stratified canopy 10?15 m high. Terra firme forest was quite stratified with canopy height approximately 30 m. Trees along the river bank and the banks themselves were covered by a dense assembly of vines, lianas, and herbaceous taxa including Cydista, Ipomoea, Heliotro- pium, Sida, Mikania, and other widespread taxa typical of low- elevation rivers of the Guiana Shield. Podostemaceae, Solanum, and Psidium often colonized rocks exposed to inundation. Soils were composed of brown sandy clays ultimately derived from granitic or doleritic substrates. The terra firme forest supported a high diversity of gen- era typically associated with these soils, namely Pouteria, Inga, and Protium. White sands and forest associated with them were not found, but further investigation of the up- per Rechter Coppename River above Bolletrie Falls will be necessary to determine the boundaries of the psammophi- lous flora associated with the Tafelberg massif. The expedition team included Claudius Perry, our Amerindian guide from many BDG expeditions, Erin Trip and Stephen Stern again joined the expedition, and Diana Gittens from University of Guyana. We moved on to the confluence of the Midden and Linker Coppename Rivers. The Midden and Linker Coppename Rivers are significant, both biologically and from a conservation standpoint, because they drain the highest elevations in Suriname, the Wilhelmina Gebergte with Julianatop being the highest point at 1,400 m.

S M I T H S O N I A N C O N T R I B U T I O N S T O B O TA N Y the confluence of the Linker and Midden Coppename (at 100 m) to the summit of the Wilhemina Gebergte is expected to contain a significant percentage of the plant diversity present in Suriname. Preservation of this water- shed is therefore highly important for conservation. Al- though only the lower reaches of both rivers was explored, the diversity documented was impressive and differed in a number of respects from that observed on the Rechter Coppename River. Forest bordering the perimeters of the Midden and Linker Coppename in all instances was formed on terraces, levees, and other features resulting from river dynamics, whereas the Rechter Coppename was dominated by terra firme forest not affected by river dynamics quite close to the main channel. Successional gradients formed over long time periods in the absence of human disturbance allowed for establishment of wind- dispersed taxa with high light requirements in seedling stages, such as Ceiba pentandra and Couratari. Both of these species were found frequently as large, buttressed, canopy- emergent taxa with heights to 45 m along the river banks. Although these taxa grow in closed- canopy forest, their presence indicates significant disturbance at the time MAP 11. Collecting localities of H. D. Clarke, Trip 21. N U M B E R 9 7 ? 5 9 of seedling establishment, in this case as a result of erosion from the shifting river channel. Geonoma and Trichilia were found to dominate river terraces, whereas levees and poorly drained forest behind levees were found to be quite diverse, with a complement of herbaceous taxa and small trees in the understory such as Psychotria, Piper, and Ri- norea, a midstory dominated by Astrocaryum, Euterpe, and Attalea, and a canopy with no clear dominants but many elements typical of low- elevation forests such as Inga, Eschweilera, Pouteria, and Licania. Canopy height was approximately 30 m with emergents to 45 m. Soils were universally brown sandy clays and were often allu- vial in origin. Relief near the river was often very limited but in a few cases amounted to 10?20 m. The plant di- versity of this area was found to differ from that of the Rechter Coppename chiefly as a result of differences in the character of the river. Together, these areas represent a pristine and diverse example of the plant diversity of this part of northeastern South America. Continued preserva- tion of this area in a state that is free from human distur- bance will help in the conservation of biological diversity and the processes that produce and maintain this diver- sity. A high priority should be placed on sampling the up- per reaches of these two rivers to document the extent to which diversity varies with elevation as the rivers descend from the Wilhelmina Gebergte. After returning to the area around Bureau Water- kracht Werken Camp, the expedition moved on to Ad- ampada Creek, an affluent of the Coppename River. The biological and conservation significance of the plant di- versity of Adampada Creek may be explained largely as a function of the smaller size of the creek compared to the Coppename River and the differences in river dynam- ics and hydrologic cycles that result. The botanical work done in Adampada Creek revealed abundant evidence of areas near the river being subjected to stronger but shorter flooding cycles than those found along the Cop- pename River. As a result the vegetation near the creek showed a more compressed transition from submerged aquatic to terra firme forest than along the Coppename River. Plant communities were sampled on various to- pographies, including a waterfall, rocky islands in rapids, steep river banks, and poorly drained and well- drained terra firme forest. These habitats were found to be closer together than along the Coppename River, making the aquatic habitats smaller and probably more susceptible to perturbation. Conservation of this part of the reserve is of particular concern because most of the watershed lies outside the reserve boundaries and is threatened by large- scale bauxite extraction. We spent the remainder of the trip along the main Coppename River, including the areas of Caiman Sula (= rapids), Sidonkroetoe Sula (= sit down meeting rapids), Driefoetoe Sula (= three- foot rapids), and unnamed trib- utaries and affluents of the Coppename River. Botanical sampling of the Coppename River below the confluence of the Rechter and Linker Coppename Rivers occurred in diverse habitats, including flooded forest on steep banks, rheophytic, emergent, and submerged aquatic vegetation, rocky islands, seasonally flooded forest behind levees, and relatively little genuine terra firme forest (although this may have been due more to limited relief and consequent poor drainage at the georeference localities than to river flood- ing per se). Vegetation differed qualitatively in these areas as a result of the more extensive and prolonged flooding on the larger section of the river. Flooded forest extended as much as 200 m behind the river bank. Although we found extensive evidence of vegetation affected by flooding, silt- ation, and formation of levees and berms, we found no evidence of successional gradients resulting from shifting river channels as we saw in the Linker Coppename River. Conservation of this part of the river will be best effected by protecting upstream parts of the river, which will pre- serve the hydrologic cycle and water characteristics. All the sites visited on the Coppename River were found to be as pristine as any other site in the Neotropics. Because they are part of a very large protected area, the Central Su- riname Nature Reserve, they may be expected to receive continued protection. In the absence of any human- induced disturbance of either aquatic or terrestrial vegetation, both species diversity and community dynamics are robust and, if afforded continued strong protection, will remain so in the future. The presence or absence of plant species in low- elevation forests of the Guiana Shield turn over more or less consistently as a function of distance, most likely as a result of an equilibrium established among speciation, dispersal, and extinction over very long time periods. The Coppename River provides an excellent example of the plant diversity that has evolved under these conditions and, given the large size of the reserve, the evolutionary and ecological dynam- ics needed to propagate these processes into the future will be maintained. The plant communities sampled were found to be composed of a unique assemblage of species, most of which have broader distributions in low- elevation areas of the Guiana Shield. The combination of species represented, however, is very unusual and the Coppename River, there- fore, is an outstanding representative of the diversity of the Guiana Shield. On this trip we were able to make 349 collections from the 24 georeference sites. 6 0 ?

The focus of these expeditions to the Pakaraima Mountains was to sample every tepui higher than 1,450 m. After this trip the only tepui not sampled in Guyana was Tulameng, at 1,490 m elevation, located at the extreme northeastern edge of the Pakaraima Mountains, which remains a high priority for sampling. Mount Maringma is important because it is close to the Roraima massif. Given its location at the eastern terminus of the chain of tepuis along the Brazil? Guyana border, Mount Maringma was expected to harbor many plants previously known only as Roraima endemics, as confirmed by preliminary results from both the slopes and summit of Mount Maringma. Notable collections in- clude those of Magnolia, Drimys, Weinmannia, Rubus, Vellozia, Heliamphora, Stenopadus, Stomatochaeta, and Gongylolepis. We approached the mountain from the Ataro River and the village of Wayalayeng, situated at the base of the mountain and next to the Falls of the Ataro River, where the river drops from 625 m to 490 m. Starting at Imbaimadai on the upper Mazaruni River, the expedition party descended the Mazaruni to its confluence with the Kukui River at Jawalla, ascended the Kukui River to the Ataro River confluence, and ascended the Ataro River to Wayalayeng. We walked from there to the summit, cut- ting trail beyond the last farm from the village to the sum- mit. The Ataro River section of the route lies within the Akawaio Amerindian village of Pipillipai. The western boundary of the village is formed by the Arabaru River, whose headwaters arise between Mount Maringma and an unnamed 1,830 m mountain south and west of Mount Maringma. Maringma itself, then, is not on village lands. After collecting extensively along the southern slopes, summit, and a sub- summit plateau of Mount Maringma, the expedition, which included Jay Rhodes, returned along the Ataro River to Wayalayeng Village. Final col- lections were made at Imbaimadai near the airstrip; along the Mazaruni River 0?7 km above its confluence with the Karowrieng River; and in Georgetown at Bel Air Park. The expedition to Mount Maringma (2,134 m) yielded 1,059 collections of plants over five weeks. The collections are noteworthy for several representatives of species collected by R. Schomburgk on Roraima in 1834 but not re- collected in the intervening 170 years. These collections came from a very small area of high- elevation cloud forest on the southern slope of Mount Maringma and, since Schomburgk?s Roraima collections were made from a southern approach and were made mostly in Brazil and Venezuela, these collections may be the only genuine Guyana records for rare and endemic taxa such as Mag- nolia ptaritepuianum, Drimys brasiliensis, Rubus guya- nensis, and Ledothamnus sessiliflorus. Detailed work on determinations, which is only now just beginning, is likely to extend this list significantly and also add a number of new species. triP 1: iWoKrama rainforeSt reSer Ve collecTions 154?400. 17 sePTemBer?9 ocToBer 1995 Iwokrama Rainforest Reserve; transect from Essequibo River to Turtle Mountain, in SW direction. 18 September 1995. 4?42?20?N 58?42?36?W, elevation 60?150 m.

Manuscripts not in compliance will be returned to the author. Manuscripts in- tended for publication in the Contributions Series are evalu- ated by a content review board and undergo substantive peer review. Accepted manuscripts are submitted for funding ap- proval and scheduling to the Publications oversight Board. MInIMuM MAnuSCrIPT lEnGTH is thirty manuscript pages. If a manuscript is longer than average, an appropriate length will be determined during peer review and evaluation by the Content review Board. Authors may be asked to edit manuscripts that are determined to be too long. TExT must be prepared in a recent version of Microsoft word; use a Times font in 12 point for regular text; be double spaced; and have 1? margins. Each chapter/section must be saved in a separate file. rEquIrED ElEMEnTS are title page, abstract page, table of contents, main text, and reference section. See the SISP Manuscript Preparation and Style Guide for Authors for the order of all elements. HEADInGS should be styled so different levels of headings are distinct from each other and so the organization of the manu- script is clear. Insert one line space above and one line space below all headings. FronT MATTEr should include title page, abstract page, and table of contents. All other sections are optional. Ab- stracts must not exceed 300 words. Table of contents should include A-, B-, and C-level headings. TABlES (numbered, with captions, stubs, rules) should be submitted in separate MS word files; should include foot- notes, if appropriate; should have rules only at top, bottom, and beneath column heads. Print outs of each table should accompany the manuscript to ensure correct layout of data. Tabulations within running text should not be numbered or formatted like formal tables, and should be included in the text of the manuscript. FIGurE CAPTIonS should be provided in a separate MS word file. FIGurES (e.g., photographs, line art, maps) should be num- bered sequentially (1, 2, 3, etc.) in the order called out; be placed throughout text, not at end of manuscript; have all components of composites lettered with lowercase letters and described in the caption; include a scale bar or scale descrip- tion, if appropriate; include any legends in or on the figure rather than in a caption. ArT must not be embedded in the main text. Figures must be original and submitted as individual TIFF or EPS files. resolution for art files must be at least 300 dpi for grayscale and color images and at least 1200 dpi for line art. Electronic images should measure no more than 100% and no less than 75% of final size when published. JPG files will not be accepted. Color images significantly increase costs so should be included only if required. Funding for color art is subject to approval by SISP and the Publications oversight Board. In-TExT rEFErEnCES should be used rather than biblio- graphic notes and should follow the author-date system in the following format: ?(author last name, year)? or ?. . . author (year)?; ?(author, year:page used within the text)? or ?. . . author (year:page).? A full citation should be included in a ?references? section. EnDnoTES are to be used in lieu of footnotes and should be keyed manually into a separate MS word file, in a sec- tion titled ?notes?. notes should not contain bibliographic information. Manually type superscript numerals in text and use full-sized numerals at the beginning of each note in the ?notes? section. SISP will determine the best placement of the notes section, either at the end of each chapter or at the end of the main text. rEFErEnCES should be in alphabetical order, and in chron- ological order for same-author entries. Each reference should be cited at least once in main text. Complete bibliographic information must be included in all citations (e.g., author/edi- tor, title, subtitle, edition, volume, issue, pages, figures). For books, place of publication and publisher are required. For journals, use the parentheses system for volume(number):pag- ination [e.g., ?10(2):5?9?]. Do not use ?et al.?; all authors/ editors should be included in reference citations. In titles, capitalize first word, last word, first word after colon, and all other words except articles, conjunctions, and prepositions. Examples of the most common types of citations are provided in the SISP Manuscript Preparation and Author Style Guide.
