Introduction

The Marquesas (7°50’-10°35’S, 138°25’-140°50’W) are one of the eastern peripheral island groups in the Pacific Polynesian Triangle. The other major high island archipelago on the eastern edge of the island-strewn central Pacific, Hawaii, has one of the most interesting and remarkable floras in the world. It has received an enormous amount of attention and, while not yet fully known, is one of the best documented tropical floras. The Marquesas were discovered by Europeans almost 200 years earlier than Hawaii (or Tahiti), but their flora has remained one of the more inadequately studied of insular floras.

The Marquesas are less isolated than Hawaii and are only about one-third as high in elevation. Their area is less than 10 percent that of the Hawaiian group. The flora is smaller and the degree of endemism less. How much smaller and how much less than the Hawaiian 95 percent endemic is not known. The total land area is only about 1275 km^2, little larger in aggregate than the islands of Tahiti and Moorea together. Distances are approximately 750 nautical miles to Tahiti, about 1900 to Hawaii, and 3000 to the Galapagos Islands.

Like the Hawaiian and Society islands, the Marquesas are high volcanic islands. Unlike the others, especially Tahiti, they lack a coastal plain and almost completely lack coral reefs. Lowland areas occur only at the mouths of rivers. The islands rise abruptly from the ocean in dark steep forbidding cliffs with scattered shrubs and vines clinging here and there. The two largest islands are also the highest, Nukuhiva (1185 m) and Hivaoa (1260 m). The volcanic masses soar to narrow steep crests, which form the backbones of the islands. The slopes below these long ridges are often eroded into cirques surrounded by precipitous slopes and cliffs, and narrowing downward into canyon-like valleys. After a break in slope, the gentler relief of some of the interfluves, occasionally broad and rather flat-topped, gives the impression of sloping, dissected plateaus ending abruptly at the coast with a sudden drop. Elsewhere, sharp and narrow ridges tumble seaward. Nukuhiva has a broad elevated interior basin with boggy areas, called the Tovii, which has certainly not been completely explored for plants. The island of Uapou is crowned with tall spires of phonolitic trachyte.

There are small steep desert islands in the group and a sand islet on a coral bank, of which very little is known.

The climate of the region is tropical oceanic, constantly warm, with high atmospheric humidity, local sporadic rain showers, and heavy orographic rainfall where the mountainous islands interfere with the prevailing easterly trade winds. However, the simple pattern of windward-leeward trade-wind effect in the Marquesas is very much complicated by the dissected topography and other factors. The “backbones” of the islands are usually bathed in mists and crowned with very mossy “cloudforest.” But on low lying areas, the trade winds exert a desiccating effect. The lower uninhabited islands, the “desert” islands, appear quite arid and there are years of prolonged drought. On the western “plateaus” of Nukuhiva and Hivaoa stretch arid areas, with a vegetation of grasses and scattered woody plants, including very interesting species, such as sandalwood and Cordia lutea, a shrub otherwise known from dry Ecuador, Chile, and the Galapagos Islands. The deep valleys contain streams, many of which are frequently dry; and the high waterfalls tumbling down the cliffs of the higher cirques often disappear.

In Atuona, on Hivaoa, masses of cool air may flow down the slopes at night and chill the village to a surprising degree. The overall picture is that, with a relatively uniform temperature and atmospheric humidity, there is great and quite unpredictable variation in rainfall (except perhaps for the crests) and a mosaic of local climates. The pattern is much less orderly and predictable than on Tahiti, for instance.

Hurricanes are unknown in the Marquesas, but tsunamis of the South Pacific have often caused extensive flooding of the small alluvial plains at the valley mouths, where the modern villages are usually located, creating extensive destruction and loss of life and crops.

A more detailed description of the geography and vegetation will be omitted at this time, because little information has become available since the work of Adamson (based in part on LeBronnec’s field work), Aubert de la Rüe (I958), Decker (1970), and others. Sachet and Fosberg (1955, 1971) include references on Marquesan vegetation. More field work is in progress or planned, and it should provide much additional material for a later detailed account of Marquesan nature. The flora is also receiving renewed attention, and later parts of this series will surely reflect this welcome interest in the Marquesas.

The Marquesan flora was included in the French Polynesian flora of Drake del Castillo (1892), as well as in his partially completed Illustrated Flora of the Pacific Islands (1886–1892), both of which were based on what casual collections were available to the author. Forest B. H. and Elizabeth D. W. Brown spent 17 months in the Marquesas on the Bayard Dominick Expedition in 1921–1922 (Brown, 1931:3–9). With more experience and better support in the field, they could have, in the amount of time available, gathered materials for a flora adequate for reasonable phytogeographic statistical comparison, at least if the accumulated material in the Paris herbarium had been included. While the Browns made reasonably good collections of the lowland flora on several of the larger islands, some of the smaller islands and most of the high mountains on the larger ones were very inadequately covered. Relatively small collections made since have yielded some remarkable finds and a high percentage of novelties (Fosberg, 1939; Fosberg and Sachet, 1966, 1975).

F. Brown’s Flora of Southeastern Polynesia (1935) is essentially a report on the plants collected on the Bayard Dominick Expedition by the Browns, on the Whitney Expedition by Quayle, Jones, and R. Beck, and by the Pacific Entomological Survey. Earlier collections not represented in the Bernice P. Bishop Museum herbarium were not included, except as they may have been recorded by Drake del Castillo. In addition, the work suffers from erratic writing and non-existent editing. There are glaring errors in identifications; under some species, full descriptions and specimen citations are included, elsewhere they are casual or partial, or absent altogether. Nevertheless, up to now, this work has remained the only modern flora available for French Polynesia, and has been very useful to many.

Martin L. Grant had accumulated in catalog form a tremendous amount of data on French Polynesia, centered on the Society Islands to be sure, but including the Marquesas as well, and his files are available to us. None of his work was published during his life-time and only a few families have recently been treated in print for the Society Islands (Grant, Fosberg, and Smith, 1974).

The inadequacy of F. Brown’s work, added to the fact that a number of collections have been made during the last 40 years, make a new flora of the Marquesas an important desideratum, even though the extensive additional field work needed has not yet been possible.

The series of papers initiated by the present one is planned to fill, to some extent, this gap in modern knowledge of Polynesian floras. It is based on materials studied in the Bernice P. Bishop Museum, the University of California at Berkeley, the New York Botanical Garden (especially the plants of J. G. Chapin), the Brooklyn Botanic Garden, and on my own collections and those of Bryce G. Decker, to be deposited in the U.S. National Herbarium, on duplicates received by this herbarium from George W. Gillett, and on small but choice collections received for identification from Francis Hallé and Henri Lavondès. Of special importance are the historical collections examined in the Laboratoire de Phanérogamie, Muséum National d’Histoire Naturelle, Paris; at the British Museum (Natural History), and Kew. These 18th and 19th century collections from the Marquesas (and from other Pacific island groups) have often been ignored in early 20th century work on the Pacific floras, as in F. Brown’s work on southeastern Polynesia. In Paris, especially, lack of staff and emphasis on other parts of the world have resulted in such specimens not being readily available for study, especially to workers in Honolulu and other American centers who could not easily travel to European institutions. Because I have been able to spend some time in Europe, though not nearly enough as yet, the present flora suffers less from inadequate attention to these historical collections.

Starting with the Forsters on Captain Cook’s second voyage in 1774, a number of European visitors, many of them French Navy surgeons or pharmacists, gathered plants in the Marquesas, on which the earlier described species were based, as were Drake del Castillo’s treatments. Prominent among these were Bennett in 1835, Hinds and Barclay in 1840, Dupetit-Thouars in 1838 and 1842, Hombron and Le Guillou in 1836, LeBatard in 1844, Mercier in 1847, Jardin in 1854–1855, Lenormand in 1857, and Savatier in 1877. I have not seen the collections made by Langsdorff in 1804 during the Russian around-the-world expedition under Krusenstern.

Unfortunately, as is the case with so many early collectors’ notations, the herbarium labels are often deficient or difficult to decipher or interpret. The collections were separated early and labeled by the owners of large private herbaria, so that duplicates of a collection may bear different labels. Dates given are often those of receipt in the herbarium rather than that of actual gathering.

The precision needed to satisfy modern requirements for typification of species is not always easy to achieve. I hope that in this respect the present flora may make a substantial contribution.

The 20th century specimens present less problems than the earlier ones and are usually numbered consecutively and clearly labeled and dated, although some include very little data. One of the most important collections, however, that of the Pacific Entomological Survey, offers complications. I worked on it in 1963 in Atuona and have studied the plants in other herbaria since then, so I will describe its history in some detail.

The Pacific Entomological Survey, under the aegis of the Bishop Museum, sponsored insect collecting expeditions in various Pacific Island groups, the most important such project being that in the Marquesas, which lasted from January 1929 to January 1932. A summary of this work, as well as a description of the archipelago, is given by A. M. Adamson (1936), one of the two entomologists of the party. The director of the party was E. P. Mumford, and together they stayed in the Marquesas until April 1930. In addition to insects and other small invertebrates, host plants were collected, mostly by Adamson and the local assistants, the principal one of whom was the Frenchman G. LeBronnec (Sachet, 1966). Together, Adamson and LeBronnec collected over 600 numbers and, after the departure of the entomologists, LeBronnec and the other assistants continued to gather insects and plants. The main collection was sent to the eminent botanist, E. D. Merrill, then Consulting Botanist for the Bishop Museum. In record time, he sent back to the Marquesas lists of preliminary identifications from Berkeley and later New York. The main collection was then distributed by Merrill. Some confusion arose at that point: All the specimens carried Bishop Museum field labels with the heading “Pacific Entomological Survey” and laboriously typed in the Marquesas in multiple copies. The actual collectors were not mentioned. In the Bishop Museum, where the main set is deposited, herbarium labels were prepared that include some of the data from the field labels and cite the collectors as Mumford and Adamson, as in Merrill’s lists of identifications. An important set remained in Berkeley, with herbarium labels prepared by Merrill, the collectors being cited as Mumford and Adamson, and little or no data included from the field labels, which therefore provide essential data when mounted on the sheets. The same is true of the partial set sent from Berkeley to the New York Botanical Garden, and of the plants received later in New York. However, some Berkeley duplicates and most New York ones are labeled “Adamson and Mumford.” There are small numbers of the Pacific Entomological Survey plants in other herbaria; and the partial set retained by LeBronnec (unlabeled, except for copies of the field labels) is now in my hands for study and will eventually be turned over to the herbarium in Paris, or at least that part of it that has not suffered too much from insect damage and other vicissitudes.

With his preliminary lists, Merrill sent advice on improving the collections and requests for additional material of sterile or inadequate specimens. After the departure of the entomologists, LeBronnec attempted to recollect the desired material, and numbered his collections “Ex 2” meaning extra material of no. 2. Starting in October 1930, he tried to find the same species again and, on the whole, succeeded remarkably well. Merrill did not see these collections, and in the Bishop Museum they were labeled “Pacific Entomological Survey.” There are other complications which need not be detailed here, but which have led me to decide that this major Marquesan collection should be cited in a uniform way, especially in a flora. As on the field labels, the collectors will be mentioned as “PES” (Pacific Entomological Survey), followed in parentheses by “M & A” (Mumford and Adamson), or “A & M” (Adamson and Mumford), or whatever collectors’ names are on the herbarium labels. Since my return from the Marquesas in November 1963, I have taken every opportunity to examine specimens of this collection in Honolulu, Berkeley, and New York, and I now have a fairly complete catalog of it, which I plan to publish at a later date.

The synonymy given in most cases is not exhaustive, but includes those names used in the literature on the Marquesas and neighboring islands, basionyms of accepted names, and what other names are useful in interpreting the usages adopted in earlier works. The references given in the synonymy, likewise, are only those needed to document the names listed and those that were sources of information incorporated into this paper. All references have been verified. Free use has been made of all published sources available, of the documents and manuscript notes accumulated over 50 years of residence in the Marquesas by G. LeBronnec, as well as of data recorded on herbarium labels and in my own notes.

Herbarium symbols accompanying citations are those of Index Herbariorum, edition V, 1964, with the addition of “Fo,” indicating specimens still undistributed by F. R. Fosberg and myself and “LeB” for the LeBronnec set of the Pacific Entomological Survey collection. Abbreviations used very frequently in synonymy are as follows: F. Brown, Flora (F. Brown, 1935); Drake, Flore (Drake del Castillo, 1892); and Drake, Ill. (Drake del Castillo, 1886–1892).

Like other island groups in the Pacific, the Marquesas were “discovered” on repeated occasions and given sets of Spanish, French, and English names in addition to their Marquesan names (Brigham, 1900:184; Jourdain, 1970). The latter are rendered with a variety of spellings depending on the nationality of the person or his knowledge of Polynesian languages. In this series of papers on the flora, the simplest spellings of the Marquesan names (Figure 1) will be used throughout, with the name as listed on the label added only when there might be some confusion. Marquesan is one of the Polynesian languages and includes at least two principal dialects: the northwest dialect of Nukuhiva and Uahuka and the southwest one of Hivaoa and Fatuiva. The main differences in pronunciation are that “k” in the northwestern dialect becomes “n” in the southeastern dialect (thus “Uahuka” is called “Uahuna” in the southern islands), and “h” (NW) is replaced by “f” (SE). There are also some cases where quite different words are used for the same thing, on different islands, and this is true of plant names. All Marquesans know Tahitian to a certain extent, and many ornamentals or other plants brought from Tahiti often retain their Tahitian names.

Of all the plant collectors who have worked in the Marquesas, few knew Marquesan. The only one who has some critical knowledge of Marquesan linguistics is Henri Lavondès, who collected a few plants in 1966. LeBronnec had good Marquesan informants, but he had to render the sounds as best he could, or following missionary usage. I will cite the names as given on herbarium labels or in books, with occasional comments when I know them to be in error. Altitudes are listed as they appear on the labels, with approximate metric conversions supplied in brackets where necessary. Such figures mean little except as very general orders of magnitude, as few botanists carry altimeters and there are no topographic maps of the Marquesas.

Indebtedness to the authorities and staffs of the institutions where I have worked and who have loaned specimens to me is gratefully acknowledged. I wish to expess my appreciation especially to the Bernice P. Bishop Museum, where I am always made to feel at home, as at the Botany Department of the University of Hawaii, and to my friends and colleagues in Paris, who, year after year, have helped me track down 18th and 19th century collections and documents. In the Marquesas, I salute the memory of a great born-naturalist, G. LeBronnec, with whom I worked every day for many weeks, and acknowledge the good-natured help of his family. In Tahiti, the former Service de l’Agriculture, the French overseas research office, ORSTOM, the representatives of the Paris Muséum d’Histoire Naturelle and, of course, the governor’s office and other branches of the government, all gave me support, advice, and help during my visits.

Outstanding has been the help of my dear friends Jean-Noël and Nora Maclet, who are still growing some rare Marquesan plants in their beautiful hillside gardens above Papeete and helping me in many different ways.

In starting this series of papers on the Marquesan flora, I wish to recognize the help of Dr. F. R. Fosberg, whose assistant I was for many years and who introduced me to Pacific studies and taught me a great deal. Perhaps most important, as a senior colleague, he has always provided me with moral support and encouragement, as well as advice, when needed.

ERICACEAE

Shrubs, subshrubs, herbs or rarely trees; leaves usually alternate, simple, exstipulate, usually more or less serrate or dentate; flowers bisexual, solitary or more usually in spikes, racemes or racemose panicles; calyx of 4–7, usually 5, variously connate sepals; corolla of the same number of petals, free or usually united, often urceolate; stamens twice the number of corolla lobes, rarely the same number, usually free, filaments rarely more or less united, anthers often appendaged, cells opening by terminal pores or slits; pistil 1, ovary superior or inferior, cells 4–10, usually 5, placentation axile, ovules usually many, occasionally as few as 1 in a cell, style 1, often curved; fruit a capsule or berry; seeds usually small, and numerous, rarely few and larger.

A large nearly cosmopolitan family. One genus in the Marquesas.

Vaccinium L.

Vaccinium L., Gen. Pl., ed. 5, 166, 1754 [= 1753].

Shrubs, dwarf-shrubs, rarely small trees; flowers usually axillary, solitary, or in small clusters; corolla typically urceolate, rarely campanulate or rotate, gamopetalous; anthers variously appendaged; ovary inferior, with many ovules; fruit a berry with many seeds, in many species edible.

Taken in a broad sense, an almost cosmopolitan genus, especially in cool or mountainous regions. One species in the Marquesas.

The genus Vaccinium is commonly represented in the higher regions of Polynesia, as well as in other Pacific islands. In southeast Polynesia, with the exception of V. rapae Skottsberg described as endemic in Rapa, all the island plants have commonly been referred to Vaccinium cereum (L.f.) Forster sensu lato, described from Tahiti.

Vaccinium cereum (L.f.) Forster f.

Vaccinium cereum (L.f.) Forster f., Prodr., 28, 1786.—Skottsberg, Acta Hort. Gothob., 8:87, 91–97, 1933.

Andromeda cerea L.f., Suppl., 238, 1781.

Small shrub, branchlets and leaf-bases somewhat puberulent to glabrous; leaves oval to broadly obovate, up to 4 × 2.5 cm, very slightly to markedly shortly acuminate, margins minutely serrulate to subentire, blades stiff, reticulate-veined, petioles very short, thick; flowers on pedicels up to 8–10 mm long, with one or two bractlets near base; calyx lobes ovate, 2–3 mm long; corolla white, ovoid-urceolate, to 1 cm long, with 5 ovate lobes; anthers with 2 subulate erect or divergent appendages; fruit purple-black, with many angular seeds.

The type is from the Society Islands.

Skottsberg (1933) made a detailed study of this species, in which he recognized two varieties from Tahiti with two forms each and one variety from Rarotonga, and he referred the Marquesan V. adenandrum to var. cereum f. eriostemon Skottsberg.

Forest Brown, on the basis of more material, regarded the Marquesan plant as V. cereum var. adenandrum, which is the disposition adopted here. Certain Marquesan specimens, in their sharply serrate leaf margins and pubescent stems resemble more var. cereum. Evidence is insufficient to tell if they constitute a separate population or are merely aberrant individuals.

Type from the Marquesas.

SPECIMENS SEEN.—Without locality, probably from the Marquesas, s.coll. no. 42 bis (US), the label says “toatoa,” which is the Marquesan name cited by Decaisne, so this sheet may be part of the type of var. adenandrum.

ETHNOBOTANY.—Jardin (101) gives the name “heua (Kanac)” from Nukuhiva, “Kanac” meaning here Marquesan (heua usually applies to Metrosideros sp. in Nukuhiva, and may have been recorded in error for Vaccinium). Decaisne gave the name toatoa, which is probably from the southern Marquesas. F. Brown (Flora) cited hueki from Nukuhiva, and puatoatoa from Fatuiva, and said the fruits are eaten in times of famine. LeBronnec (MS) tried to identify “toatoa” with the help of old Marquesans, whom he considered to be reliable informants. They could only report that they had heard it said that it was a plant of high regions, the seed of which was used in medicine.

EPACRIDACEAE

Shrubs or small trees; leaves alternate or spiral, usually stiff, small, veins subparallel, exstipulate; flowers usually bisexual, actinomorphic, pedicels often bracteate; calyx 4–6 lobed, persistent; corolla gamopetalous, 4–6 (usually 5) lobed, aestivation imbricate or valvate; stamens same number and alternate with lobes, attached on corolla or basally, often alternating with tufts of hair or glands, anthers 1–celled, dehiscing longitudinally; pistil 1, ovary superior, 1–10 celled, placentation axile, ovules 1 to many in a cell, style 1, stigma capitate; fruit a capsule or drupe.

Mainly Australasian, with scattered outliers in Polynesia, Micronesia, and Malesia. One genus in Polynesia.

Styphelia J. E. Smith

Styphelia J. E. Smith, Spec. Bot. New Holland, 45, 1795.

Cyathodes Labillardière, Novae Holland. Pl. Sp., 57, 1804–06 [1805].

Ericoid shrubs; leaves rather crowded, small, stiff, entire; flowers axillary, pedicels with imbricate bracts; corolla short, tubular, lobes recurved or reflexed at least in age; fruit a rather mealy drupe.

A genus of many species, mostly Australian, some Melanesian, a very few Polynesian, one Micronesian. One variety of a Hawaiian species in the Marquesas.

Styphelia tameiameiae (Chamisso & Schlechtendal) F. v. Mueller

Styphelia tameiameiae (Chamisso & Schlechtendal) F. v. Mueller, Fragmenta, fi:55, 1867.

Cyathodes tameiameiae Chamisso & Schlechtendal, Linnaea, 1:539, 1826.

Leaves patent, broadly to narrowly elliptic, stiff, up to 1 cm long, dull green above, whitish with darker veins beneath, these forked once or twice and somewhat spreading distally; corolla white, 3 mm long, lobes triangular, pilose within, more or less hooked at apex; fruit subglobose to depressed globose white to purplish on one side or maroon.

A common Hawaiian species with several forms or varieties in southeastern Polynesia. In Hawaii the species occurs over a great altitudinal range and exhibits a perplexing array of variations that have yet to be elucidated. In the Marquesas, one variety very close to, but distinguishable from, the Hawaiian ones, is found at higher elevations on Nukuhiva.

Styphelia tameiameiae var. marquesensis F. Brown

Styphelia tameiameiae var. marquesensis F. Brown, Flora, 218, 1935.

Styphelia tameiameiae var. tameiameiae sensu Sleumer, Blumea, 12:162, 1963.

Styphelia tameiameiae f. marquesensis (F. Brown) Grant, Fosberg, and Smith, Smithsonian Contr. Bot., 17:10–11, 1974.

Twigs densely short pubescent or puberulent; leaves oblong-elliptic 9–15 × 2–3 mm, leaf veins usually less forked than in var. tameiameiae, outer ones forked one or more times, inner 1–3 quite parallel, some slightly forked once, rarely more times, bracts more strongly ciliate; flowers with corolla-lobes triangular-lanceolate, glabrous within; noticeably hooked; fruits usually red (e.g., Decker 379, Brown 533), rarely white to rose (Decker 2014).

In most respects within the range of variation of the Hawaiian forms, but with consistently long narrow leaves, narrower glabrous, hooked corolla lobes. Sleumer (1963:162), however, could not find “any constant character to separate the Marquesas specimens from the Hawaiian forms.”

In spite of Brown’s rather confusing publication of this “form Marquesensis F. Brown, new variety,” it seems best cited as var. marquesensis F. Brown. Grant (Grant, Fosberg, and Smith, 1974:10) discussed this plant but found no distinguishing characters, so did not separate it from S. tameiameiae.

Found only on Nukuhiva, at high altitudes, locally common in scattered localities. Fruit reported (Brown 533) to be eaten by “cuckoo,” probably the “kuku,” or Marquesan fruit pigeon.

MYRSINACEAE

Vines, shrubs, and trees, often with dark glands, leaves simple, unlobed, usually alternate, exstipulate; flowers unisexual or bisexual, actinomorphic, solitary, in axillary fascicles, terminal or axillary cymes, racemes or panicles; sepals 4–6, separate or united at base, often reddish or black-punctate, persistent; corolla gamopetalous, tube usually very short, lobes 4–6, valvate or imbricate; stamens usually attached to the corolla, opposite the lobes, rarely connate, anthers 2–celled; pistil 1, ovary superior, rarely inferior, locules 1 or 4–6, ovules 1 to many, placentation free-central or axile, placentas complex, surrounding ovules; fruit fleshy, baccate or usually drupaceous, with 1 to few seeds.

Pantropical, with a few temperate zone species. One genus with several Marquesan species.

Until recently, only F. Brown (1935:219) had recognized the occurrence of this family in the Marquesas, and he cited under Rapanea myricifolia f. marquesensis all the material available to him. R. myricifolia Gray, however, does not occur in the Marquesas.

Myrsine L.

Myrsine L., Gen. Pl., ed. 5, 90, 1754 [=1753].

Rapanea Aublet, Hist. Pl. Guiane, 1:121, 1775.

Small trees; leaves usually entire, rarely denticulate, sessile to short-petiolate, usually coriaceous or subcoriaceous, obscurely or clearly pinnately nerved, with or without a marginal nerve; flowers dioecious, axillary, solitary or in fascicles, usually borne below the leaves, pedicellate to subsessile, those of the 2 sexes similar except that the nonfunctional parts are smaller; calyx united at extreme base, sepals scale-like; corolla rotate, tube very short, lobes longer than tube, imbricate; stamens with anthers longer than filaments; pistil with superior ovary, 1-celled, ovule attached basally, style very short, erect, stigma peltate, sugar-loaf-shaped or ligulate; fruit a globose drupe with thin flesh, stone globose, with one seed.

Pantropical genus, usually found in montane situations, of which most species have been called Rapanea. The differences between Myrsine and Rapanea are in shape of leaf, distribution on the stem, margin denticulate vs. entire, and ill-defined stigma differences. Until something more substantial is found, it seems best to recognize only one genus in this relationship. The Marquesan plants have all been previously referred to Myrsine (or Rapanea) myricifolia, which is a different Fijian species.

Study of recent collections led to the separation of several new species (Fosberg and Sachet, 1975). Because this is such a difficult group the original descriptions of the species are cited here in full. More collecting is very much needed (cf. Grant, Fosberg, and Smith, 1974:14).

Myrsine tahuatensis Fosberg & Sachet

Myrsine tahuatensis Fosberg & Sachet, Smithsonian Contr. Bot., 21:10, 1975.

Shrub 4 m tall, glabrous, young branchlets 5–7 mm thick with leaves crowded at intervals, more widely separated between the crowded portions, leaf scars transversely elliptical with a broad depression above; leaves obovate, sessile, up to 22 × 11 cm, apex obtuse to slightly bluntly acuminate, base somewhat auriculate or cordate, blade minutely and irregularly black-punctate, especially beneath, becoming stiff and subcoriaceous, main veins 14–22 on a side, visible above and beneath, irregularly placed, opposite to alternate, diverging at somewhat different angles, decurrent into the broad midrib, forking distally and anastomosing in arches that do not reach the margin, network obscure, especially beneath, older branchlets mottled light gray (possibly from lichens), bearing, below leaves, irregularly spirally disposed fascicles of 4–7 thick scaly divergent inflorescence branches up to 5 mm long and 2.5 mm thick. Flowers and fruits unavailable, except for a single detached fruit with mottled, dark and pale minutely pebbled surface, obviously immature—its sides rather collapsed, presumably subglobose when fresh, 3 mm long, on a thick short pedicel, 1.5 mm long, 1 mm thick, fruit subtended by a whorl of 3 thick calyx-lobes (another perhaps abortive), connate at base, broadly triangular, papillate, apex of fruit crowned by a short coroniform stigma of 3 or 4 lobes (one perhaps damaged or poorly developed), from an extremely low ring-like tube, lobes bluntly acuminate, irregularly incurved.

This species is represented by rather inadequate material but seems closest to M. taitensis Gray of Tahiti. It differs in larger, somewhat thinner, completely sessile leaves and in the conspicuously fasciculate (branched at base), much longer inflorescences, as well as in having the leaves tending more to be crowded into intervals on the branchlets (“croissance rythmique nette” Hallé).

OLEACEAE

Trees or shrubs, sometimes scandent, leaves opposite, rarely alternate or subalternate, simple or compound, exstipulate; flowers bisexual in usually few-flowered fascicles, cymes or panicles, sepals free, corolla gamopetalous (rarely absent), actinomorphic, lobes 4 or 5, valvate or imbricate, stamens 2, ovary superior, 2-loculed, with 2 or more ovules in a cell, style 1, stigma minute, fruit a capsule, berry, drupe, or samara.

A rather small, widely distributed family, containing the domestic olive and a number of ornamentals, including the lilacs, privets, and jasmines. Only one genus, Jasminum, in the Marquesas. The olive tree was imported into the Marquesas, and LeBronnec (MS) mentioned seeing a large tree in Taiohae, probably in 1929 or 1930, which never bore fruit. There are no collections and no recent observations.

Jasminum L.

Jasminum L., Gen. Pl., ed. 5, 7, 1754 [=1753].

Vines or scandent shrubs; leaves usually opposite, unifoliolate or pinnately compound; flowers in few-flowered cymes; calyx funnel-form or campanulate, with 4–9 teeth; corolla salverform, lobes 4–10, imbricate, stamens included; fruit a geminate berry with 2 seeds in each half.

Old World genus with a number of cultivated ornamental species; several species known from the Marquesas, possibly one native.

Jasminum didymum Forster f.

Jasminum didymum Forster f. Prodr., 3, 1786.—F. Brown, Flora, 225, 1935.

This species was reported by Brown from the Marquesas and other islands, but he cited no specimens (nor indeed of the other species of Jasminum he discussed), and I have found none in the herbaria where I have worked. It may be a misidentification. The plant, however, is commonly found in other islands of southeastern Polynesia, and there are many collections from Tahiti, so it might occur in the Marquesas.

The following description is based on specimens from other islands of Polynesia. Liana with glabrous, sprawling, scrambling, or rarely somewhat twining stems, leaves trifoliolate, petioles 1–2 cm long, petiolules 4–15 mm, leaflets usually very broadly ovate or elliptic or oval, up to 9 × 5 cm, obtuse to acuminate, usually with 5 rather strong nerves from just above base, rather plinerved, base rounded to subcordate. Inflorescences loosely thyreoid in axils, occasionally terminal on small branches, minutely puberulent, branches of thyrse dichasioid, the lateral pedicels branched with 2 flowers, central pedicel 3–5 mm, whole thyrse up to 13 × 5 cm, usually much smaller, with up to 4 internodes in main axis; flowers rather small for the genus, calyx campanulate to cylindric, about 3 × 2 mm, truncate except for minute blunt denticulation on margins, corolla salverform, tube about 5–7 mm long, lobes 4–7, suborbicular about 3 mm long, white, very fragrant; calyx in fruit somewhat enlarged and pedicel swollen, obconic; fruits 2, or one of them variously reduced or aborted, globose, 8–10 (−15) mm long, black.

Described from the Society Islands. The Tahitian name, tafifi, means a twining liana, and is also used for other twiners.

LOGANIACEAE

Habit various, latex none; leaves simple, opposite, joined at base by transverse ridges or inter-petiolar stipules; inflorescences basically cymose, sometimes circinnate, reduced to fascicles, or elaborated into cymose panicles or thyrses; flowers 4–5 merous, calyx united at base or part-way up, corolla gamopetalous, lobes valvate or imbricate, stamens alternate with corolla lobes, attached in tube or throat, anthers 1–2-celled, longitudinally dehiscent, ovary usually superior, 2-loculed, ovules numerous, style 1 or 2 with a common stigma; fruit capsular or fleshy, usually septicidal, seeds usually many, rarely reduced to one.

A medium-sized mostly tropical family, seemingly very unnatural in its usual circumscription; as treated here somewhat reduced by removal of Fagraea to Gentianaceae. Few indigenous genera in oceanic Pacific islands.

SPECIMENS SEEN.—Tahuata I.: “Région du sommet du Tahuata,” 17 Mar. 1973, F. Hallé 2170 (US, holotype, P, MPU, isotypes).

Very closely allied to G. astylum Gray of Tahiti, differing in the smaller less oblong leaves, much smaller, more contracted inflorescences, which are not or scarcely thyrsoid, in the more usual presence of bracteoles on the pedicels, in the somewhat acuminate much more ciliate calyx lobes, and in the corolla more densely bearded within.

Apparently very rare, one plant only seen by collector. A sterile specimen collected on Hivaoa, Feani, at 700 m, F. Brown 1096 (BISH), may be the same.

GENTIANACEAE

Herbs, shrubs, or trees, usually smooth, leaves opposite, simple; flowers 4- or usually 5-merous, calyx gamosepalous, lobed; corolla gamopetalous, lobes variously imbricated or plicate and usually contorted in bud; stamens 5, inserted on the corolla tube alternating with the lobes, anthers 2-loculed; pistil 1, ovary superior, 1 or 2 celled with parietal or axile placentation, ovules and seeds many.

Almost cosmopolitan, with only herbaceous members in temperate zones, herbs, shrubs, and trees in the tropics. One genus in the Marquesas (which is usually put in the Loganiaceae).

Fagraea Thunberg

Fagraea Thunberg, K. Vetensk. Acad. Nya Handl. (Stockholm), 3:132, 1782.

Shrubs and trees with leathery leaves, stipules paired, intrapetiolar, connate with petiole at base, flowers in cymes, very fragrant, corollas campanulate to tubular salverform; fruit a many-seeded berry.

An Indo-Pacific genus, usually placed in the Loganiaceae, a family that seems artificial and better clarified by removing such extraneous elements as Fagraea.

Fagraea berteriana Gray ex Bentham

Fagraea berteriana Gray ex Bentham, Journ. Linn. Soc. Bot., 1:98, 1857.—Drake, III., 238, 1892; Flore, 139, 1892.—F. Brown, Flora, 228, 1935.

Tree, cymes few flowered (buds up to at least 16), corolla white, turning creamy yellow, waxy, salverform, with 5 rounded to slightly obovate spreading to recurved lobes; anthers linear, basally inserted below summit of throat; ovary superior, cylindric, style thick-filiform, stigma bifid into two broad flat lobes; fruit orange to red, 3.5–5.5 cm long with juicy pulp and seeds embedded in it.

A widespread polymorphic species, with many varieties, extending from Queensland and New Guinea east to the Marquesas and north to Micronesia, carried around by Polynesians as an ornamental, so that its original range in Polynesia is very difficult to determine. Originally described from Tahiti. One variety known from the Marquesas differs from the Tahitian var. berteriana in the shorter corolla tube, 4–6 cm rather than 6.5–8 cm, and from another, undescribed Tahitian variety in its included rather than exserted stigma.

ETHNOBOTANY.—The Marquesans valued all flowers and fragrant plants, and Fagraea was one of their most important ones. The Marquesan name for this species is pua, which means flower. They were made into crowns and garlands, used to perfume coconut oil to rub over the body and in the hair. The red fruit called kaupe served in funeral rites. There were also some medicinal uses of the bark and other parts of the tree.

Leaves broad, elliptic or oval, obtuse to acute, 9–13 × 3.5–7.5 cm, secondary veins 13–20 on a side, strong, connected at margin by a marginal vein that arches between adjacent secondary veins, glabrous or almost so; petiole about 4 cm long; corolla white 11–13 mm long, with lobes to about 6 mm long, obtuse to acute; style 2.5 mm long; follicles 19–29 cm long, 4–5 mm wide; seed 7–9 mm long, proximal appendage frequently forked.

This species is conspicuously variable in size and shape of leaves, size of cymes and length of follicles. It is perhaps too close to A. costata R. Brown of the Society and Cook Islands. A component of montane forest on high ridges on the larger islands.

Alyxia Banks ex R. Brown

Alyxia Banks ex R. Brown, Prodr. 469, 1810 [nom. cons.].

Gynopogon J. R. & G. Forster, Char. Gen. 18, 1775; 35, t.18, 1776.

Twining vines or shrubs, leaves opposite or whorled, usually rather small, flowers in small axillary pedunculate cymes, corollas small, salverform, fruit a pair of subglobose carpels, each with a single stone or with two or more moniliformly arranged stones, the whole often reduced by abortion to one drupe or an end-to-end pair of drupes.

An important Indo-Pacific genus, centered in Malesia and New Caledonia, with at least one representative in almost every high island in Polynesia and Micronesia.

Alyxia stelfota (J. R. & G. Forster) Roemer & Schultes

Alyxia stellata (J. R. & G. Forster) Roemer & Schultes, Syst. Veg. 4:439, 1819.

Gynopogon stellatum J. R. & G. Forster, Char. Gen., 18, 1775; 36, 1776.—Forster f., Prodr. 19, 1786.

Alyxia stellata, described from the Society Islands and Tonga, extends in various forms from at least as far west as New Caledonia to the Marquesas and Henderson Island. It is supposedly distinguished from A. scandens (also from Polynesia but not known from the Marquesas) by ternate vs. opposite leaves, but these occur too often on the same plant. It seems to be more reliably distinguished from A. scandens by considerably smaller flowers.

F. Brown (1935:230–231) placed all Marquesan material in his f. marquesensis, while admitting its variability. Three varieties are now recognized from the Marquesas.

Alyxia stellata f. marquesensis F. Brown, Flora, 230, 1935 [pro parte].

Shrubby vine; leaves in whorls of 3, coriaceous, broadly elliptic, venation obscure to visible, apex somewhat acuminate but with tips rounded, bases rounded to acute, margins closely revolute; cymes about 1 cm long (to 2–2.5 cm in old fruiting specimens) 3–5 flowered; sepals triangular-ovate, puberulent, orange; corolla greenish yellow; drupes sub-globose, about 1 cm long, black.

Most of the Marquesan material is rather uniformly like the above description. Found in forest from dry areas to cloud forest on wet crests.

ETHNOBOTANY.—Species of Alyxia were as important in the Marquesas to make fragrant garlands (hei) as in Tahiti and Hawaii. The Marquesan name is meie (meie papa in Fatuiva). F. Brown mentions also mehe but this is probably a different plant, possibly Morinda umbellata. Jardin (1857: 297, 314) lists an Alyxia but, from the name (katea) cited, this is more likely a species of Wikstroemia.

ETHNOBOTANY.—According to Jouan, this plant was introduced into Tahiti in 1839 and into the Marquesas (Nukuhiva) at the very beginning of the French occupation in 1842, and was spreading around Taiohae when he left in 1856. Jardin said the Marquesans made soft cushions from the seed plumes. Both give the name “kirika,” a borrowing from the English “silk.” Related names are kirita (Decker 1762), puakirita (Herb. S.F.I.M. 20), and uru uru vaikirita (PES Ex 71). Still other names: “herbe de Mme Boivin,” LeBronnec (MS) and F. Brown (1935:237) cite also vevai from Fatuiva.

Pantropical, said to be of American origin, widely cultivated as the “moon-flower” and frequently naturalized; two doubtful collections from the Marquesas. Jardin’s record of Calonyction speciosum is probably this species but his specimen (179) has not been seen. Delmas’ description fits this species, which he reports to be rare and often confused with I. macrantha.

ETHNOBOTANY.—Pohue (PES 22) is a general name for morning-glory lianas in Tahiti and the Marquesas. Delmas says it applies to two species of Ipomoea besides I. alba. For the latter, he gives pohue nui (large pohue) or pua mahati, and pohue mata nui for the large white flower, and mahati for the whole plant or the seeds used as a purgative. Jardin records this use and the name mahati for his no. 179 (not seen).

ETHNOBOTANY.—The general names for this species are sweet potato, patate douce, and, in the Marquesas, kumaa (Nukuhiva) or umaa (Hivaoa, PES 327, 330, umaa papaoa, PES 438). F. Brown (1935:239) gives some names of varieties. So does LeBronnec (MS) who lists from Nukuhiva: “Kumaa Alierton, K. Dore, K. Pearson (these three imported by Ch. Henry), K. huahua moa, K. Pikino, K. Rapanui, K. Rurutu, K. tavaie,” obviously most of these imported from other islands. I was surprised, in 1963, to see very few plants of this species in Hivaoa and did not collect it. Decker (pers. comm.) observed that the very abundant rat populations of the islands made it unprofitable to plant sweet potatoes, unless they could be watched constantly. Other crops requiring less vigilance and hard work in clearing the land are planted in preference, even though the Marquesans like sweet potatoes very much.

While there is some evidence that the sweet potato was present on Easter Island before the arrival of Europeans, there is no conclusive proof that the same was true in the Marquesas. Indeed Mendana, who discovered the islands in 1595, mentioned neither finding nor planting them there (Brand, 1971:357, 359). Identification of plant remains from an archeological site on Uahuka (Kirch, 1973:35) did not include sweet potato. This site, excavated by Sinoto and Kellum in 1964, was dated (Sinoto, 1966:295, 302) as about mid-12th century A.D. None of this proves that the sweet potato was not present, of course, and, at any rate, it was fairly common at the end of the 19th century. Jardin (1857:315) makes the interesting remark that in the 1850s it was beginning to be cultivated by natives of Taiohae and Atiheu (Nukuhiva) not for their own use, but for sale to whalers. Jouan (1865:115), who left the Marquesas in 1856, records similar facts, but says that it is a recently introduced white variety, which is cultivated by the European residents for sale to whalers, a variety different from the generally yellow “Camotes” of Peru. Jardin gives the name kumaa, but mentions also two other varieties, titau mei and titau kaikaha. These, however, are varieties of yams, Dioscorea. F. Brown (1935:238) discussed uses and varieties, but some of his interpretations have been discounted by the foremost student of Pacific Islands sweet potatoes, Douglas Yen (1971:339). Yen (1974) collected 26 specimens from 5 islands in the Marquesas as part of his extensive study of the biology, genetics, and distribution of this species.

Quamoclit vulgaris Choisy, Mém. Soc. Phys. Hist. Nat. Genève 6:434, 1833.—Jardin, Mém. Soc. Sci. Nat. Cherbourg, 5:297, 1857.

Slender glabrous twiner; leaves pinnately divided into linear or filiform lobes; peduncles axillary, much longer than leaves, 1-several flowered, bracts nearly obsolete; pedicels 1–3 cm long, tending to be thickened toward apex; sepals oblong, obtuse to rounded, mucronate, corolla bright red, about 3 cm long, very narrowly funnelform, limb short but deeply lobed; capsule ovoid, obtuse at apex, glabrous, tending to split rather irregularly, valves thin, seeds glabrous, mottled brownish on black.

Pantropical species cultivated for its feathery leaves and small but bright red flowers.

This species has previously been known from the Pacific only from Fiji and Tonga, where it was formerly usually called Ipomoea jastigiata (Roxburgh) Sweet. Otherwise it is tropical American. The Marquesan collections seem to represent a distinctive population with a few characters uncommon or absent in the variable, widespread American species.

Ipomoea tiliacea var. merremioides Fosberg

Ipomoea tiliacea var. merremioides Fosberg, in Fosberg and Sachet, Smithsonian Contr. Bot. 21:14, 1975.

Glabrous climber but not very conspicuously twining, leaves thin, blades triangular-ovate, much longer than wide, up to 10 × 5 cm, apex tapering-acuminate, base broadly and strongly cordate with a U-shaped sinus and rounded basal lobes, petioles slender, notably shorter than blades; inflorescence umbelloid in appearance but a condensed, once to twice ramified, cymose panicle on a long peduncle, to 13 cm, pedicels much longer than branches, these 1–16 mm, bracts minute, scale-like, sepals elliptic or elliptic-oblong to slightly obovate, about 8 mm long, obtuse, outer ones mucronate, corolla funnelform, 3–3.5 cm long, limb only slightly flaring, 2.5–3 cm wide, “rose-mauve,” stamens included in basal ⅓ of throat, unequal in length, shorter than style, anthers very narrowly sagittate, straight, 2–2.5 mm long, filaments subulate, glabrous apically, increasingly beset with short gland-tipped hairs below, pollen grains globose, very shortly spinulose; pistil 16 mm long, ovary sub-globose, glabrous, style filiform, glabrous, stigma irregularly capitate, fruit globose, about 5 mm high, subtended by an entire disk, usually somewhat asymmetric, glabrous, beaked with persistent short style-base, this somewhat off-center, only one seed developed, this shot-like, 4 mm across, with 2 basal somewhat flattened areas edged on outer parts with sparse brown wool, scar light brown, obovate, surrounded by horse-shoe-shaped very low ridge, general seed-surface dull sooty brown.

The Marquesan specimens differ from those of Fiji and Tonga, as well as from the vast majority of the American ones, in being glabrous, in the much smaller much more funnelform, less flaring corollas, enlarging abruptly above the calyx, the abruptly short-mucronate rather than more gradually acuminate-aristate sepals, the usually much longer peduncles, and the entire, long-acuminate leaves rather than more or less orbicular, dentate or lobed.

Convolvulus turpethum L., Sp. Pl., 155, 1753.

Coarse subglabrous twiner with angled to winged stems (Marquesan specimens weakly angled, not winged); leaves elongate triangular with slightly hastate base to orbicular cordate, with broad basal sinus, puberulent; peduncles with 1–3 flowers, pedicels becoming very thick, 2–4 cm long, bracts less than 2 cm long, early caducous; calyx lobes large, orbicular, apex rounded to obtuse, sharply mucronate, 2–3 cm long, sericeous, somewhat accrescent; corolla broadly campanulate, 5–6 cm long; capsule globose, about 1.5 cm long, or somewhat more; seeds black, glabrous.

Apparently very rare in the Marquesas, no definite localities known.

SPECIMEN SEEN.—Marquesas Islands: s.l., Dupetit-Thouars 20 (US). Nukuhiva I.: Henry 57 (P).

LOCAL NAME.—Pania oke (Dupetit-Thouars 20).

Stictocardia Hallier f.

Stictocardia Hallier f., Bot. Jahrb., 18:159, 1894.

Large twiners; leaves glandular beneath; peduncles axillary, bearing cymes; sepals elliptic to orbicular, greatly accrescent and thickened in fruit; corolla funnelform-campanulate; stamens and style included, pollen spinulose; stigmas 2, globose; capsule completely enclosed by accrescent calyx, globose, 4-celled, the septa with transverse wings, wall thin, irregularly dehiscent leaving the septa and their wings enclosing seeds; seeds pubescent.

Pantropical, with one species in the Marquesas.

Differs from Ipomoea only in the glandular leaves, the thickened closed fruiting calyx and the structure of the capsule.
