INTRODUCTION 
The Biological Diversity of the 
Guianas Program 
The "Biological Diversity of the Guianas" 
(BDG) 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 Guianas (Guyana, Surinam, and 
French Guiana). The program has been 
operating since 1983. It was originally confined 
to botany within Guyana, which was at that time 
the least known of the three Guianas. It has 
since been expanded to include faunal studies, 
but field work in countries other than Guyana 
has been minimal to date. In Guyana the BDG 
operates under the auspices of the University of 
Guyana (UG) with whom it has a Memorandum 
of Understanding. 
The Guianas are a biologically diverse area, 
and unlike many other tropical countries, 
approximately 70% of the natural habitat of the 
Guianas remains pristine. Most of the land is 
owned by national governments, most of the 
people live along the coast, and until recently the 
destructive development of the interior was kept 
to a minimum. As a result there is a real 
possibility that large tracts of extremely 
interesting forest and their accompanying biota 
can be conserved. These natural areas are now 
seriously threatened by resource extraction 
activities such as practiced by Asian logging 
companies and Brazilian gold miners. It is 
important that we gain an understanding of the 
flora and fauna so that decisions can be made 
concerning critical areas that have high priority 
for conservation and so that data can be collected 
from areas that will ultimately be degraded. In 
addition, because this region has been long 
neglected by biologists, it is often an area of 
"insufficient information" for many biological 
studies. For many years most collectors bypassed 
Guyana in particular. The program was designed 
to provide specimens and data to address 
biodiversity questions about many groups of 
organisms for research and conservation 
projects. This new information is now being 
used to produce checklists, vegetation maps, and 
floristic and faunistic studies. In addition, the 
BDG program is exploring uses of these data that 
will lead to a synthesis of information addressing 
broader biodiversity issues and understanding 
(Funk and Richardson, 2002). 
Prior to the BDG's work, Guyana was little 
known biologically, with sparse documentation 
of its biota. In 15 years of collecting the BDG 
Program has produced works important to the 
understanding of Guyana's biological diversity 
and in 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), the Iwokrama area 
(Clarke et al., 2001), and Kaieteur National Park 
(Kelloff and Funk, 1998). It has also published a 
Checklist of the Birds of Guyana (Braun et al., 
2000). Data from the BDG program have been 
used in many publications; a complete list of

Guyana Plant Collections: L.J. Gillespie 
these can be found on the program's website at 
http://www.mnh.si.edu/biodiversity/bdg/bdgpub.htmL 
In addition to these lists, checklists of the 
herpetofauna and mammals of Guyana can be 
found on the BDG website, and they will be 
published by the contributors in the near future. 
The BDG fulfills the goals of the 
Smithsonian Institution by gathering new 
information and distributing it to encourage 
production of floras and faunas of poorly known 
areas; participating in training students and 
professionals from the host country, supplying 
data for the identification and preservation of 
biologically diverse areas; and providing 
specimens for systematic studies both within the 
Institution and throughout the world. Although 
the program operates out of the Smithsonian, wc 
depend on extensive collaborations throughout 
the world to accomplish our goals. Currently we 
have over 100 scientists with whom we interact 
(see our website for a full list of collaborators 
and other information about the BDG). 
From 1986 until 1998 the BDG maintained a 
resident plant collector in Guyana. More 
recently the program has had resident butterfly 
and bird collectors, and there are plans underway 
to base an ant collector in Guyana. Botanical 
specimens collected through the program have 
been distributed to a network of experts for 
identification and a set of specimens is deposited 
at UG, the US National Herbarium in 
Washington DC, and many other botanical 
institutions. At the time of this publication the 
BDG program has collected approximately 
44,200 numbers, representing over 225,000 
individual specimens. 
Lynn J. Gillespie 
Lynn Gillespie was the third Resident Plant 
Collector to participate in the BDG Program. 
Over a nearly 19 month period, she spent 12 
months in Guyana and approximately 135 days 
in the field. She collected 2510 numbers, which 
were processed by the U.S. National Herbarium 
at the Smithsonian Institution. This processing 
included distribution to specialists for 
determination and to other botanical institutions 
as part of specimen exchange programs. 
Currently just over 85% of these plants have 
been identified to species. These determinations 
show that Lynn Gillespie collected over 1200 
taxa in 610 genera. Copies of her field 
notebooks and mounted vouchers for her 
collections are now in the herbarium housed at 
the "Centre for the Study of Biological 
Diversity" at the University of Guyana.

travelling on the Canje River. Photo C. Kelloff. 
Several Guyanese accompanied Gillespie on 
her collecting trips. Those who assisted with 
collecting, as recorded on the specimen labels, 
include; D. Gopaul, L. Kelly with the University 
of Guyana Forestry Class, H. Lall (Figure 2; 
name changed to H. Persaud, March 1989), and 
S. Tiwari. The Guyanese who assisted in 
Georgetown include M. Ameer and G. Bacchus. 
Other participants in collecting trips include V. 
Funk, M.E. Gillespie, RJ. Gillespie, C. Kelloff, 
T. McDowell, P. Peterson, and D.R. Smart. 
The assistance of Dr. George Walcott, Vice- 
Chanceilor of UG, Dr. Indarjit Ramdass, head of 
the UG Biology department, and the staff at the 
U.S. Embassy in Georgetown, Guyana was 
invaluable. Dr. Walcott made the entire 
operation possible by proving to be the crucial 
person in developing the project. Dr. Ramdass 
helped considerably in facilitating Field trips and 
providing logistical support, and the U.S. 
Embassy helped with handling and shipping of 
supplies and specimens collected by Gillespie. 
Without all of their help, the program would not 
have succeeded. 
Dr. Gillespie is an expert in the plant family 
Euphorbiaccae and is currently a Research 
Scientist at the Canadian Museum of Nature in 
Ottawa. Her publications include work on the 
Euphorbiaccae   of Guyana   (Gillespie,   1993a; 
Guyana Plant Collections: L.J. Gillespie 
1993b; 1994; Gillespie and Armbruster, 1997). 
She continues to collaborate with the BDG 
program by providing determinations of 
collections in that family.

Format of Collection Information 
These data summarize identification of 
plants collected by Lynn Gillespie and identified 
by hundreds of taxonomic specialists. One 
purpose of this publication is to make the results 
of this field work widely available to the 
botanical and conservation community now that 
over 85% of these collections have been 
identified and distributed. This publication will 
also serve as a resource for many herbaria that 
received sheets of these collections. As is 
always the case with such endeavors, specialists 
may revise their determinations of specimens, 
and data errors are corrected over time. In 
addition to this publication, the BDG website 
(see below) with these data will be periodically 
Part I presents notes by the collector on the 
localities, habitats, and events of the collecting 
trips. The Canje River (Trip 12) section was 
contributed by Carol Kclloff. 
Part II is a detailed account of the localities 
at which Gillespie made her collections for the 
BDG program, organized chronologically by 
trip. The range of 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 dates for those 
collections, latitude and longitude coordinates, 
elevation ranges in meters, habitat descriptions, 
collection number ranges, and co-cottectors. 
Latitude and longitude are given in degree (?), 
minute ('), and second (") format. These 
collections were made before affordable Global 
Positioning Systems (GPS) were available; 
coordinates were usually recorded only to the 
nearest minute and, accuracy varies as locality 
determinations were made in the field using 
maps of varying quality. 
Part III is a set of maps indicating the 
localities for each of Gillespie's collecting trips 
outside of Georgetown. As stated above, the 
accuracy of these positions is subject to the tools 
that were available to collectors at the time. 
Part IV is a listing of the collections in 
numerical order. Each number is followed by 
the determined plant family, plant name 
including any infraspecific names that are 
available, and authors of the name. The BDG 
generally maintains plant name information as 
submitted by specialists, and these may be 
checked against the synonymy provided in the 
Checklist of the Plants of the Guianas, T 
Edition (Boggan et al., 1997), or in the 
Preliminary Checklist of the Plants of the 
Guiana Shield. Volume 1: Acanthaceae - 
Lythraceae (Holfowell et al., 2001), both of 
which are available in hard copy from BDG or 
online at http://www.mnh.si.edu/biodiversity/bdg. 
In many eases commonly accepted names are 
listed following the recorded name. The authors 
of plant names follow standardized abbreviations 
(Brummitt and Powell, 1992). 
Guyana Plant Collections: L.J. Gillespie 
Part V is a listing of collections by 
determined name, sorted by division, family, 
genus and specific epithets followed by the 
collection numbers for each name. Specimens 
not 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. 
The Appendix, "Botanical Collecting in 
Guyana," is a personal account by Lynn 
Gillespie of the plant collecting experience in 
Guyana, written to provide the lay reader with a 
feel for the challenges and satisfactions of field 
work in Guyana. It also serves as an 
introduction to the purpose and procedures of 
collecting botanical specimens and adding them 
to herbaria. 
In general, the first sheet of determined 
specimens have been distributed to the Centre for 
the Study of Biological Diversity at the 
University of Guyana (ERG) with a second sheet 
deposited at Smithsonian's U.S. National 
Herbarium (US). Anyone requiring additional 
information about the distribution of duplicate 
specimens to other herbaria or about the 
specialists who participated in the determination 
of specimens can contact the BDG Program at 
the US National Herbarium, MRC 166, 
Smithsonian institution, Washington DC, 20013- 
7012 USA. 
This is the second publication by the BDG 
detailing the collections of the program's plant 
collectors. The first publication covered the 
collections of John J. Pipoly from 1987 to 1988 
(Hollowell et a!., 2000). As identification of 
collections by other BDG field botanists 
becomes at least 80% complete, additional 
publications will be issued in this series. This is 
publication number 63 in the Smithsonian's 
Biological Diversity of the Guianas Program 
publication series.

PART I: NOTES ON TRIPS 
Trips 1-3: Georgetown Vicinity, 19 February to 
2 March 1989 
These were day trips from Georgetown. The 
first trip was to the Mahaica area, along the coast 
east of Georgetown, where collections were 
made on a beach and in a highly disturbed 
scrubby area bordering a water conservancy 
canal. The second two trips were to white sand 
savanna and evergreen sclerophyllous forest 
south of Georgetown along the Linden Highway. 
Trip 4: Kato - Kaicteur. 17 March to 1 April 
1989 
The Kato section of the trip was organized 
and led by BDG collector William J. Hahn. The 
team included Gillespie, Harry Persaud from the 
UG Herbarium, Mike Tamcssar, the zoologist 
from the UG Museum, SI mammalogist Don 
Wilson, and SI hcrpetologist Bob Reynolds. All 
arrived in Kato by helicopter on March 10 and 
were comfortably housed in a temporary medical 
camp run jointly by the Guyana Defense Force, 
Ministry of Health and the U.S. Army. 
Collections were made in the vicinity of Kato 
and Paramakatoi, both Patamona Amerindian 
villages, and along the trail connecting the two 
villages. Following the return from Paramakatoi 
by helicopter (accompanied by a live Bushmaster 
in a carry-on bag) and the departure of the 
medical camp, the team had ample time to 
explore Kato and its surroundings during the 
nine-day wait for an expected plane. The rolling, 
mid-elevation countryside around the village is 
primarily savanna with scattered small trees (e.g. 
Plumeria), shrubs (e.g. Bysonima), and palm 
stands {Mauritia flexuosa). The lower slopes are 
mostly covered in a low to medium height 
semi-evergreen forest. The picturesque Chiung 
River, in a valley just west of Kato, was the 
favorite bathing spot, and in addition it had a 
botanically interesting riparian zone with 
colourful Norantea (plate 1) and Marcgravia 
vines. One interesting plant collected here was 
Passiflora quelchii (plate 2), unusual in this 
genus as a shrub and the first collection record 
for the Guianas. Plant collections from the 
Kato-Paramakatoi section of the trip (March 
10-28) were made under Harm's collection 
number series (5556-5808), with the exception 
of those made by Gillespie March 17-19 (such as 
in figure 3) during Hahn's absence on an 
organizational trip to Georgetown.

ascidia Feuillet, collected near Kato Village. 
Gillespie & Persaud 831. 
The team departed Kato by small plane on 
March 29, sharing the flight with two female 
traders returning with their hoard of Brazilian 
toilet paper, soap, and spades. Hahn returned to 
Georgetown, while the rest of the team was 
dropped off in Kaicteur National Park. Gillespie 
took over as leader for the Kaieteur section of the 
trip (March 29-April 1). The team settled in for 
a three-night stay at the Resthouse overlooking 
spectacular Kaieteur Falls (figure 4). The 
surroundings were a botanist's paradise, with 
giant mauve bladderworts (Utricularia 
humboldtii, plate 4) emerging from huge 
terrestrial  bromeliads  (Brocchinia  micraniha), 
16 Guyana Plant Collections: L.J. Gillespie 
numerous orchids and Rapateaceac (plate 3), to 
mention just a tiny part of the Park's incredible 
diversity of plants. 
Figure 4. Kaieteur Falls 
Trios 5 and 7: Georgetown Vicinity. 14 April 
and 30 April 1989 
These were day trips from Georgetown to 
the mouth of the Essequibo River, in the region 
called West Coast Demcrara. Collections were 
made in disturbed forest and scrub near the coast. 
Trio 6: Mainstay - Pomeroon River. 20 to 26 
April 1989 
Gillespie and Harry Persaud departed 
Georgetown on April 19 for a wecklong trip to 
Mainstay and the Pomeroon River. They 
traveled by ferry across the Essequibo Delta to 
Adventure, and then by taxi north along the coast 
to Anna Rcgina, the Administrative Centre of 
Region    2    (Pomeroon-Supenaam). After 
obtaining all the necessary permits, they 
continued on to Mainstay, an Arawak 
Amerindian village, which was their base for the 
next three days. Collections were made in the 
surrounding white sand forest and by boat in and 
along the shores of a series of lakes: Mainstay, 
Capoey and Tapakuma. They returned to Anna 
Regina where they were based for the next 
couple of days. One long, enjoyable day was 
spent collecting from a small speedboat along the 
margins of a riparian swamp forest on the 
Pomeroon River, running from Charity 14 miles 
uprivcr to the Arapiako River. 
Trip 8: Kaieteur, 5 to 8 May 1989 
After almost missing a chartered plane, the 
team departed Georgetown on May 4 for a scenic 
flight to Kaieteur under clear skies. The team 
included S. Tiwari (Herbarium, University of 
Guyana), Ron and Madge Gillespie (the 
collector's parents from Canada). Soon after 
arriving, Lynn Gillespie collapsed in the 
Resthouse with the flu, leaving Tiwari and Ron 
Gillespie to tackle the plant collecting for the 
first few days. The numerous bags of plants they 
hauled in kept Madge and Lynn Gillespie busy 
pressing and numbering on the Resthouse 
veranda, with one of the best views in the world. 
Once recovered, Lynn Gillespie and Tiwari 
joined the Guesthouse caretakers for a boat trip 
on the Potaro River and some excellent 
collecting in the riparian forest. Paddling within 
sight of the top of Kaieteur Falls, much loo close 
for the collectors' comfort, the water was 
amazingly calm and peaceful, with the roar of 
the waterfall and the rising mist not far away. 
One of the most common riparian shrubs was 
"whitcy" {Inga seriulifera, Fabaceae, 
Mimosoideae), a favorite local edible. The 
shrubs were laden with plump yellow pods, 
which have a tasty white flesh around the seeds. 
On May 9, the day of departure, the team 
waited hours beside the tarmac runway 
surrounded by endemic savanna plants. The 
plane finally arrived at the far end of the runway, 
unloaded a huge pile of beer, and almost took off 
without the team but with a full load of other 
passengers, until the pilot realized who had 
actually chartered the plane. After the plane was 
unloaded for a second time the team piled in for 
a stormy, rough ride back to the city. 
Trip 9: Omai - Essequibo River, 27 May to 6 
June 1989 
Guyana Plant Collections: L.J. Gillespie 17 
This 10-day trip (May 26 to June 5) to Omai 
was organized courtesy of Placer Dome, a gold 
mining company. Gillespie and Harry Persaud 
joined geologist Randy Singh for the 4-hour 
drive south on roads of exponentially decreasing 
quality. A very narrow, waterlogged track 
through dense forest finally led to Yaya Landing 
on the Essequibo River. After waiting out a 
downpour, the team traveled by boat upstream 
and across the river to Omai Camp. At the time 
of the visit Omai was a small mining exploration 
and survey camp sitting on a rich gold deposit 
(the gold apparently found in quartz veins of a 
diorite intrusion). The rolling terrain was 
explored using the numerous rough tracks and 
paths that criss-crossed the 36 km2 area. 
Although mostly covered in forest on red 
lateritic soils, there had been many disturbances 
by previous small mining activities and selective 
logging. 
Figure 5, The Essequibo River at Omai 
There was excellent collecting by boat along 
the mostly densely forested banks of the 
Essequibo River. The water level was high, 
inundating much of the shoreline vegetation. 
Although few trees or shrubs were flowering, 
fruits were abundant. The team explored a 
tributary creek through the inundated forest, 
where most shrubs and trees grew in over a 
meter of water and each appeared to harbour a 
major ant nest. The team members had never 
seen such a high density of ants on vegetation! 
Cut branches had to be dunked in the creek to get 
rid of hundreds of ants, while all had to brush 
hundreds off of themselves. The seemingly 
perpetual newspaper shortage once again 
curtailed collecting for the last couple of days. 
By the time of departure, Yaya Landing was 
underwater. The pickup truck backed into the 
river, the boat pulled alongside and all jumped 
aboard for the bumpy ride back to town. 
Trip 10: Kanuku Mountains - Rupununi 
Savanna, 17 June to 7 July 1989 
The team included D. Gopaul (Herbarium, 
University of Guyana), Paul Peterson (Botanist, 
Poaceae specialist, SI) and Laurccn Pierre 
(Amerindian Research Unit, University of 
Guyana). After a two-day delay the team finally 
departed on June 16 in an Islander airplane for a 
three-week trip in the Rupununi savannas. The 
destination was Dadanawa, a cattle ranch in the 
southern Rupununi savannas, but reports of rain 
and a wet, muddy landing strip forced the plane 
to land instead at Lethcm, administrative centre 
of Region 9 and the major town of Southern 
Guyana. Thinking that they would have to stay 
in Lethem for several days, they were very 
pleasantly surprised at the unexpected arrival of 
Sandy deFreitas, co-owner of Dadanawa, who 
had come to town to shop and meet the team. 
All squished into the small pickup truck for the 
5-hour ride to Dadanawa on a dirt track, crossing 
numerous creeks on rickety log bridges and 
through many deep puddles. This was the rainy 
season in the Rupununi Savannas, the one area 
of Guyana with very distinct wet and dry 
seasons. 
Comfortably settled into the Dadanawa 
guesthouse and well fed on beef three times a 
day, the team explored the surrounding savanna 
and the riparian zone along the adjacent 
Rupununi River. Collections were also made in 
a "bush island", an area of forest on drier, 
somewhat elevated land, surrounded by savanna. 
To reach the next destination, Sand Creek 
Village, Gillespie traveled with the supplies by 
boat down the Rupununi River, while the others 
hiked and botanized. The team was based in a 
small house kindly provided by the village, from 
where they explored the adjacent, partly flooded 
savannas. Two schoolboys led the team up 
Baboon Hill, a granitic rock outcrop with a 
completely different flora, including cacti, 
gesneriads {Sinningia, plate 5), bromeliads and 
Gentianaceae. That night, the eve of June 24, the 
team joined the entire village in their St. John the 
Baptist celebrations, which involved a large 
bonfire, running over the bed of glowing coals at 
the stroke of midnight, all followed by a party 
Guyana Plant Collections: L.J. Gillespie 
with Brazilian music and salsa dancing. The 
next day the team set off on a 4-day trip into the 
southeastern part of the Kanuku Mountains with 
guides Alcidio, Stanislaus, Christy and 
Cashmire. They hiked over partly flooded, very 
muddy savanna, through forest with scattered 
bush farms, and up densely forested slopes, 
finally emerging onto an extensive upland 
savanna. Base camp was established on this dry 
rolling savanna near a creek bordered by a low 
gallery forest. One long day was spent exploring 
nearby Mt. Ishtaban, climbing through mesic 
forest on the lower slopes to granitic cliffs and an 
almost impenetrable thicket near the summit. 
t.wt* 
sTr^ 
Figure  6.   Plant  collecting  on  the  Rupununi 
Savanna. 
On the day of return to Sand Creek, the 
guides rose very early to return to a patch of 
Ischnosiphon (Marantaceae) seen previously, 
returning at breakfast time with two new 
backpack frames (warishis) with which to carry 
the heavy loads of pressed and preserved plants. 
For the last part of the trip Gillespie returned to 
Dadanawa and collected on the surrounding, 
botanically rich savanna, bush islands and rocky 
outcrops, while Peterson and Gopaul ventured 
further south in search of new grasses. Note that 
grasses collected on this trip arc included in 
Peterson's number series (7495-7646). 
Trip 11: Aurora - Cuyuni River. 3 to 20 October 
1989 
The seventeen day trip to Aurora was 
organized courtesy of the mining company, 
Dennison Mines. Departing October 3, at the 
start of an early rainy season, Gillespie and 
Tiwari traveled by the large GDF helicopter over 
the Essequibo River and up the winding, milky 
brown Cuvuni River for about 110 miles, They 
landed at Aurora, an abandoned gold mine that 
had operated during the 1940's. Dennison had 
recently established an exploration camp here, 
the base camp consisting of six large wood 
frames covered with tarps in a small clearing on 
the banks of the Cuyuni River. Comfortably 
settled in, the team explored the surrounding 
area, a patchwork of mature and disturbed, non- 
flooded rainforest and seasonally flooded 
riparian forest (including Brownea, plate 8). 
Each day they ventured further afield on several 
recently cleared tracks and new survey lines 
through the forest, usually making it back to 
camp before the frequent afternoon 
thunderstorms and heavy downpours. Canopy 
trees swayed and groaned in the strong winds, 
with several falling quite close to the team, 
providing excellent canopy collecting. The team 
collected extensively by boat in the riparian 
forests (Mora, Inga, and Triplaris) along the 
banks of the Cuyuni River and its maze of 
islands, channels and tributaries. 
Departure was delayed several days since 
the helicopter was not available. Instead, 
Dennison made arrangements with a local boat 
captain for the trip back to Georgetown. Early in 
the morning under cool, gray skies, several 
Dennison staff members and team departed in a 
large, open wooden boat for the long trip 
downriver. Passing numerous gold dredges 
while sheltering from torrential downpours under 
tarps, the first part of the trip went smoothly. 
Then after passing over a series of small rapids, 
the boat arrived at Kamaria Falls, a long set of 
rapids. With three large outboard engines at full 
speed, the laden boat flew off each wave crest, 
crashing into the next wave, with the spray 
drenching all aboard. The boat and crew arrived 
safely in Bartica in the early evening and 
continued on to Georgetown the following 
morning. 
Trip 12: Canie River. 27 to 31 October 1989 
Lynn Gillespie and George Bacchus 
organized the trip up the Canje River. The team 
included Gillespie, Carol Kelloff (BDG Program 
Coordinator), Bacchus (retired surveyor and 
experienced boatman) and S. Tiwari. 
Arrangements were made in New Amsterdam for 
the rental of a boat and engine. After leaving the 
New Amsterdam vicinity with its sawmills and 
houses, the team began collecting plants along 
Guyana Plant Collections: L.J. Gillespie 19 
the river's edge in what Bacchus called the "new 
forest area". In order to make the Ikawaru 
"stelling bon," or boat house, by dark, collecting 
had to be cut short for the day and the team just 
watched the river flow by. The next morning 
they continued up the Canje River. Talking was 
almost impossible over the roar of the motor, so 
Bacchus was signaled by hand when the team 
wanted to stop to collect. Collecting continued 
along the river until reaching the Digitima 
Savanna, also locally called the "cow savanna," 
several miles south of Mora. 
Figure 7. Palicourea rigida Kunth, on the Canje 
savannas. Gillespie, Kclloff & Tiwari 2516. 
The white sands of this area support a 
grass/sedge flora with bush islands of scrub and 
small trees. According to Bacchus, feral cows 
roamed the savanna. No cows were apparent, 
but the "cow flop" indicated that they had passed 
through recently. Although on first inspection 
the flora of the savanna looked homogeneous, 
this was not the case. There were actually many 
micro-habitats and one did not have to travel far 
to sec a new assemblage of herbs. The savanna 
was extensive, and in the distance the 
vegetation's color varied. In some instances this 
indicated a damp depression supporting huge 
populations of Bulbostylis and other sedges. The 
bush islands also varied. Some were stands of 
Mauritia palms surrounded by a dense growth of 
ferns, while others were dominated by Fabaceae 
trees with little undcrstory. One morning a 
stinkhorn fungus was found growing in cow 
dung. Its cap had long, thin, pale arms radiating 
out like those of a brittle starfish; its center was 
brown and viscous and was visited by many 
flies. By late morning the heat of the day had 
withered this stinkhorn to nothing. 
Armadillos ran through the grasses of the 
savanna. The black flics were merciless, 
constantly flying into every orifice of the face. 
Their bites did not sting, but by the end of the 
day any exposed skin was covered with red 
welts. October is generally a dry month, but the 
team experienced several light rains. These 
brought out another group of biting flics called 
"kabaras". From dusk until dawn these tiny flies 
bit with such ferocity that all were driven into 
their mosquito nets. Ant hills, formed of soil 
piled a foot high and two to three feet wide, 
dotted the savannas. The "crater" in the center 
led to a 3 inch hole where ants moved in and out 
of the nest. Soldiers stood at various points on 
the nest, moving only at signs of danger. Both 
termite and ant nests were common on trees and 
below ground. 
On the trip back to New Amsterdam, the 
team stopped on the other side of the Canje 
River at another expanse of savanna known as 
Long Savanna. Here they collected the 
carnivorous plants Drosera and several species 
of Utricitlaria as well as two species of Polygala 
different from those of Digitima Savanna. More 
riparian trees were collected while moving down 
the river. The team spent another night at the 
Ikawaru stelling bon. Gas for the boat's motor 
was in short supply, so collecting along the river 
was discontinued on the last segment of the trip. 
Trips    13.14.15:    Georgetown    Vicinity,    25 
November, 1 December and 8 December 1989 
Trip 13 was a local collecting trip in 
Georgetown. Trips 14 and 15 were day trips 
from Georgetown. The first was to mangrove 
swamps and disturbed shorelines in the East 
Coast Demcrara area east of Georgetown. The 
second trip was to dry evergreen forest on white 
sand along the Socsdyke-Lindcn Highway south 
of Georgetown. 
Trip 16: Imbaimadai-Karowrieng River. 14 to 29 
December 1989 
Team members Gillespie, D. Smart 
(University of California) and camp manager 
George Bacchus traveled by small plane to 
Imbaimadai, for an 18 day trip in the northwest 
Pakaraima Mountains. Imbaimadai, a local gold 
dredging and panning centre, is located on the 
upper Mazaruni River in a broad upland valley 
20 Guyana Plant Collections: L.J. Gillespie 
surrounded by sandstone mountains. The team 
first explored the white sand savannas and low 
evergreen forest surrounding the village. They 
then traveled by boat up the Karowrieng River to 
Maipuri Falls (plate 6), where they established a 
base camp in a clearing below the Falls. 
From their base camp, a simple wood frame 
covered with a tarp, the team explored and 
collected. The surrounding lower montane forest 
was wet, lush, and medium-height due to 
shallow soils, with aroids and Cyclanthaceae 
common in the understory. South of camp was a 
shrub savanna on sandstone outcrops. Having 
explored the area accessible from camp, 
Gillespie and Smart hiked back to Imbaimadai, 
collecting along the way, to make arrangements 
for guides. With two Amerindian guides, the 
team climbed the steep sandstone escarpment 
south of camp. Collections were made in an 
interesting shrub savanna community on top of a 
large, flat topped, isolated pinnacle on the very 
dissected escarpment edge. Located on a rock 
face at the base of the escarpment were the 
ancient Timehri rock paintings. Following 
obscure trails through dense wet forest, they 
explored the mountainous area north and west of 
camp. Moving quietly through the forest, the 
team was able to closely approach a 
Cock-of-the-rock, a spectacular bird endemic to 
the Guiana region. On their return to 
Imbaimadai, the team collected along the way in 
the diverse mosaic of savanna and forest between 
the Karowrieng and Partang Rivers. From 
Imbaimadai, the team made a long one-day trip 
by boat up the Mazaruni River, collecting in the 
bordering gallery forest. 
Trip 17: Ituni Savannas, 16 to 19 January 1990 
This was a four day trip to the Ituni 
Savannas, a southern extension of the 
"Intermediate Savannas" located southeast of 
Ituni about 150 km south of Georgetown. The 
team was comprised of Gillespie, Tiwari, Vicki 
Funk and Tim McDowell (the new BDG plant 
collector). Collections were made in white sand 
savanna and open forest. 
Trips 18 &. 19: Kuru-Kuru Creek - Lamaha 
Canal; KaJeteur, 10 to 11 November and 16 to 19 
November 1991 
Though her full year of work for the 
Smithsonian ended in January 1990, Gillespie 
returned to Guyana in November 1991. She 
made two day trips from Georgetown, the first 
south to evergreen forest and shrub on white 
sand, the second east to the Lamaha Canal near 
Mahaica. A five day trip was made to Kaieteur 
National Park. Collections were made of the 
riparian vegetation and aquatic plants along the 
Potaro River, mostly above the Falls, upstream 
15 km to the first set of rapids. She also 
explored the shrub savannas on sandstone 
bedrock west of the airstrip, where a euphorb 
tree {Peru bicotor, figure 8) was discovered in 
full bloom, completely covered in small fragrant 
yellow blossoms (actually pscudanthia made up 
of tiny staminate flowers enclosed in globose 
bracts).

APPENDIX: BOTANICAL COLLECTING IN GUYANA 
L. J. Gillespie 
Biological Diversity of the Guianas Program 
July 1990 
Carefully pressing some diminutive ferns 
between pages of the Guyana Chronicle, 1 looked 
up to admire my surroundings. The Chiung 
River was cascading over dark pink sandstone 
just a few meters away. Hummingbirds darted 
among colourful arching inflorescences of the 
liana Norantea (plate 1), pausing to sip nectar 
from the bright red sac-like bracts. The gallery 
forest, a narrow band of trees along the river, had 
already proved to be rich with unusual plants. 
Beyond the forest were small creeks lined with 
fan palms and steep open slopes leading to our 
base camp on a vast upland plateau. A flash of 
white and yellow in the foliage of a nearby shrub 
caught my eye. Approaching, I discovered 
several large passion flowers hidden among its 
leaves. I had not been familiar with any shrubs 
in this genus of vines known for their showy 
flowers and edible fruit. This turned out to be a 
wonderful discovery. The shrub was later 
identified as Passiflora quelchii, the first record 
for the Guianas and the third collection of this 
species in the world! (Hahn & Gillespie 5767, 
plate 2) 
Guyana is perched just above the equator 
between the great deltas of the Amazon and 
Orinoco rivers on the northern shoulder of South 
America. With a total population of 750,000, 
about 90 percent of the inhabitants live on the 
rich agricultural land along the coast. The 
natural vegetation of the "interior" remains 
largely undisturbed. About the size of the 
United Kingdom, Guyana has seven to eight 
times the number of native vascular plant 
species. During my year spent there as a field 
botanist, I was overwhelmed by the great 
diversity of its flora and fauna. Working for the 
Smithsonian Institution's Biological Diversity of 
the Guianas Program in Washington DC, in close 
collaboration with the Biology Department of the 
University of Guyana, our purpose was to 
sample, catalogue and describe this amazing 
diversity of plants and animals. We organized 
expeditions of 2 to 6 weeks duration, to explore 
and collect in the most remote areas of Guyana 
where transportation is limited primarily to 
footpath and river. 
Guyana's long geological history and diverse 
geomorphology have contributed significantly to 
the evolution of its unusual and very diverse 
flora and fauna. Approaching Guyana by air 
over the Atlantic Ocean one can appreciate the 
vastness of the interior behind the narrow coastal 
strip of towns and farms. This low-lying coast, 
built up primarily from rich sediment washed 
ashore from the Amazon's outflow, was home to 
mangrove and freshwater swamp forests, both 
now highly disturbed by man. Flying inland by 
helicopter, we soon left the drained fields of rice 
and sugarcane. Looking down, we saw a mosaic 
of savannas and open, seasonal forest growing 
on the white sand of old beaches. Further on we 
reached the rainforest, a broad band sweeping 
south west across the country on alluvial and red, 
lateritic soils. This is the home of Greenheart, 
one of the world's most valuable timber trees. 
Although well known in Guyana, where it has 
been commercially important for many years, the 
tree was only recently assigned to a new genus, 
Chlorocardium, of the Lauraceac or Bay family. 
We flew over many miles of first flat and then 
gently undulating forest canopy, a dense treetop 
patchwork of many rich shades of green with an 
occasional patch of bright yellow. Suddenly the 
bare rock of a vast escarpment confronted us. 
Winding up the narrow Potaro River gorge, we 
rose over 741 foot high Kaieteur Falls, the 
largest in Guyana and site of Guyana's only 
National Park. The escarpment marks the 
eastern edge of the Guiana Highlands, composed 
of layers of sandstone, kilometers thick and too 
old even to contain fossils. Further inland the 
sandstone has been heavily eroded into flat 
topped, steep sided mountains called tipus (or 
tepuis as they are more commonly known 
outside    Guyana). Beneath    this    ancient 
sedimentary rock lies a basement of Precambrian 
igneous rock, one of the oldest rock masses in 
100 Guyana Plant Collections: L.J. Gillcspic 
South America. Mostly covered by the 
sandstone layers, a large outcrop of this rock 
mass forms the Kanuku Mountains in the middle 
of the Rupununi Savannas. 
One of our expeditions was to the 
southwestern Kanuku Mountains. Getting to our 
base camp in the middle of the wet season had 
not been an easy task. We flew in a small twin 
engine plane, bursting with field botanists and a 
month's worth of food and supplies. We left 
Georgetown, the coastal capital, and headed 
south, landing in Lethem, the major town of the 
Rupununi Savannas. Taking advantage of a 
short dry spell, we were able to travel by jeep 
across the mud and standing water of partially 
inundated savannas to a cattle ranch in the 
southern Rupununi Savannas. From there a boat 
carried us down the Rupununi River, a small 
trickle in a dry bed most of the year, then at the 
point of overflowing its steep banks. Finally 
with our goods piled high on an ox-cart (figure 
9), we walked the remaining distance to Sand 
Creek, an Amerindian village nestled along the 
southern edge of the Kanuku Mountains. 
Warmly welcomed, we were soon participating 
in the annual festival of St. John the Baptist, 
watching everyone from children to 
grandmothers and finally ourselves walk on the 
glowing embers of a large bonfire. To our 
amazement, walking on fire could be done with 
no pain, using the right combination of firewood 
and timings The next day we traveled by foot 
with our Amerindian guides up into the Kanuku 
Mountains.

Sand Creek, on the Rupununi Savanna 
Our camp in the Kanuku Mountains was a 
simple but comfortable place beside a sparkling 
creek. We constructed the two shelters that 
would be our home for the next week, each a 
framework of slender tree trunks over which we 
spread a large waterproof tarp. From our 
hammocks, through mosquito nettings, we 
looked out across rolling, upland savanna and 
beyond to forested peaks (figure 10). Behind us 
were the creek and its narrow band of relatively 
lush gallery forest. Listening to the frogs, we 
tried to get to sleep early; the next day would be 
a long day of exploring and plant collecting. 
At sunrise we took advantage of the 
coolness of the early morning, and set off with 
our plant collecting gear, consisting of a plant 
press, newspaper, pruning shears, a trowel, 
plenty of large plastic bags and a field notebook. 
Initially, we explored our immediate 
surroundings, collecting savanna grasses and 
flowering herbs. Whole plants, root and all, 
were placed between folded pages of newspaper 
and carefully arranged with flowers open. These 
sheets were then placed in a plant press 
consisting of two wooden boards strapped tightly 
in order that the plants dry flat and as thin as its 
newspaper. Jn this way large numbers of plants 
can be transported and stored for study in the 
world's many herbaria. Shrubs and trees were 
sampled by clipping off foot-long pieces of 
branch including flowers, leaves and, if present, 
fruits. With our treasures of a laden plant press 
and giant bags stuffed full of spiny palms, 
Heliconia (a relative of bananas), wild guava 
fruit, flowering cashew and numerous yet-to-be- 
identified plants, we headed back to camp under 
the blazing mid-afternoon sun. The air was thick 
with kabaras. These tiny, pervasive flies that 
mark the wet season swarm around you 
whenever you sit still for more than a few 
minutes. We were fortunate that they 
disappeared at dusk as we worked well into the 
night by the flickering light of our kerosene 
lanterns. To form a permanent scientific record, 
every plant collected must be given an 
identification number which is recorded in the 
collector's notebook along with its locality and a 
description of its size, flower colour and other 
distinguishing features that may not be well 
preserved. Sometimes plants are dried in the 
field in a large portable drier consisting of a 
metal frame with a skirt of canvas; kerosene 
stoves provide the heat that rises up through 
corrugated metal sheets stacked alternately with 
Guyana Plant Collections: L.J. Gillespie 101 
the sheets of plants. However on this very rainy 
trip we simply bundled the sheets together and 
placed them in large plastic bags along with a 
solution of ethanol to preserve the plants until we 
arrived back in Georgetown.

Mountains. 
On several other expeditions we visited the 
Pakaraima Mountains in western Guyana. These 
highlands include perhaps the most spectacular 
scenery as well as the greatest concentration of 
endemic flora. Roraima, Wokomung and 
Ayanganna, three flat-topped steep-sided tipus, 
are the highest peaks in Guyana, each over 6,000 
feet high. Although forests cover much of the 
Pakaraimas, savannas are a very conspicuous 
part of the landscape. In the northern, wetter half 
of the mountains with sandstone outcrops and 
thin soil, there is an unusual kind of savanna 
very characteristic of the Guianan region. The 
dominant plants belong to the pineapple, yellow- 
eyed grass and Rapatea families (Bromeliaceae, 
Xyridaccac and Rapateaceae, respectively). 
These give the savannas a very bizarre and other- 
worldly appearance, very different from the grass 
dominated Rupununi Savannas. These massifs 
formed the setting for Conan Doyle's "The Lost 
World". Although his strange creatures probably 
do not exist, numerous species of plants and 
animals exist here that are found nowhere else. 
Giant Bladderworts 2 meters tall, of the genus 
Utricularia, grow in the cupped bases of 
bromeliad leaves (plate 4). Unusual terrestrial 
orchids and insectivorous pitcher plants and 
sundews grow in cracks in the ancient, blackened 
sandstone. 
A walk through a Guianan rainforest is 
always a thrilling experience for a temperate 
zone botanist. Rarely does a shaft of light 
penetrate to the dark forest floor. It is not the 
impenetrable and colourful "jungle" that one 
expects; instead there is a spacious feeling with 
the high ceiling and dark green understory. 
Relatives of common houseplants, including 
miniature palms, Prayer Plants, Dieffenbachia 
and Spathiphyllum, grow on the forest floor as in 
a garden. Scattered on the ground we see 
delicate pink flowers, heavy globose monkey 
pods over a foot in diameter and shiny red seeds, 
recently fallen from the canopy. Over 30 meters 
above our heads, the massive straight tree trunks 
disappear into a canopy of tangled branches and 
leaves. This is perhaps the most challenging 
place to collect plants. With clipper poles, 
primers mounted on adjustable poles and 
manipulated by means of a long rope, we can 
reach 8-10 meters to some lower branches, vines 
and epiphytes. But to reach the canopy the trees 
must be climbed using either ropes slung from 
sturdy branches and the climbing equipment of 
cavers and rock climbers, or with "tree climbers" 
which are large, curved, spiked metal bars that 
are strapped to the feet. 
After a long field trip we were glad to return 
to Georgetown for a few days of relaxation. 
Unfortunately there was still plenty to do so we 
soon got back to work. Plants preserved in the 
field must be dried, then mounted on stiff sheets 
of paper and labeled with their number, locality, 
date and vegetation type; this end product is an 
herbarium specimen which can be easily 
examined and stored. Because tropical floras are 
so diverse and so little is known about them, one 
is frequently unsure when collecting in the field 
if a plant is new to science.  For example, there 
102 Guyana Plant Collections: L.J. Gillespie 
arc about forty species of Passiflora known from 
Guyana out of a total of about 600 species 
worldwide. The herbarium specimens are sent 
around the world to specialists who work on a 
particular plant family or group. Armed with the 
botanical literature, some dating back to the time 
of Linnaeus and even before, and with the 
available specimens of that group, the specialist 
can then decide what is new. 
Looking back on my year in Guyana, I feel 
privileged to have had the opportunity to explore 
the interior and to become familiar with its 
tropical flora. A country with such incredible 
biological diversity that is still relatively intact is 
rare in South America, as it is in the rest of the 
world. But even during that short time, I became 
aware of major changes that may threaten this 
unique environment. New roads are being cut 
through the rainforest, opening the area to 
lumbering operations and the potential for large 
scale deforestation. An increasing number of 
gold and diamond miners are seeking their 
fortune in the interior, resulting in mercury 
pollution of the rivers and destruction of river 
bank habitat. An active trade in wildlife, 
particularly birds and monkeys has the potential 
for significantly reducing populations. Now is 
the time to develop a conservation program and 
set aside large areas of the interior as reserves or 
parks, so that future generations may enjoy what 
I have experienced.
