SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION
Emphasis upon publication as a means of “diffusing knowledge” was expressed by the first
Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a
program that included the following statement: “It is proposed to publish a series of reports,
giving an account of the new discoveries in science, and of the changes made from year to year
in all branches of knowledge.” This theme of basic research has been adhered to through the
years by thousands of titles issued in series publications under the Smithsonian imprint,
commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the
following active series:
Smithsonian Contributions to Anthropology
Smithsonian Contributions to Astrophysics
Smithsonian Contributions to Botany
Smithsonian Contributions to the Earth Sciences
Smithsonian Contributions to the Marine Sciences
Smithsonian Contributions to Paleobiology
Smithsonian Contributions to Zoology
Smithsonian Folklife Studies
Smithsonian Studies in Air and Space
Smithsonian Studies in History and Technology
In these series, the Institution publishes small papers and full-scale monographs that report
the research and collections of its various museums and bureaux or of professional colleagues
in the world of science and scholarship. The publications are distributed by mailing lists to
libraries, universities, and similar institutions throughout the world.
Papers or monographs submitted for series publication are received by the Smithsonian
Institution Press, subject to its own review for format and style, only through departments of the
various Smithsonian museums or bureaux, where the manuscripts are given substantive review.
Press requirements for manuscript and art preparation are outlined on the inside back cover.

Introduction
The fifth installment of the Flora of Micronesia treats eight
families in the Engler system from the Bignoniaceae through
the Rubiaceae. Of the families treated here, two, Pedaliaceae
and Plantaginaceae, are entirely introduced, 1 species each.
Bignoniaceae are represented by 16 genera, all introduced
ornamentals, except one native species; Gesneriaceae by 4
genera, one native with 3 endemic species, and 3 introduced
ornamental genera with one or two species each; Lentibulari-
aceae with a single genus in Micronesia with 4 probably native
but widespread species; Acanthaceae with 14 genera, five of
them with one or more native species, all but one of them also
with ornamental or weedy species; Myoporaceae with one
genus in Micronesia with a native but not endemic species; and
Rubiaceae with 28 genera, 21 native, seven introduced, 17
exotic species, and many native, mostly endemic taxa.
This installment follows essentially the format of the first
four (Smithsonian Contributions to Botany 20, 24, 36, and 46).
Further and more complete bibliographic detail may be found
in Sachet and Fosberg, Island Bibliographies (1955) and its
supplement (1971), with annotations and a complete list of
serial abbreviations.
For details of the history and circumstances of the present
Flora of Micronesia, as well as an explanation of its scope and
arrangement, reference may be made to the introductory pages
of the first installment.
In specimen citations, the collector’s name and number are
italicized and the herbaria where they are deposited are
indicated only if the specimen has been examined by the
authors. Herbarium symbols are according to the 7th edition of
Index Herbariorum, Part I, compiled by Holmgren and Keuken,
F. Raymond Fosberg, Marie-Helene Sachet (deceased), and Royce L.
Oliver, Department of Botany, National Museum of Natural History,
Smithsonian Institution, Washington, D.C. 20560
1981. These are in parentheses after the collection numbers, or,
lacking numbers, the dates. The abbreviations “s. 1.,” “s. coll.,”
and “s. n.” are used to indicate lack of collection locality,
collector’s name, or collector’s number, respectively. We wish
to thank again, the authorities of the various herbaria where we
have studied or borrowed material, for the privilege of using
their collections and for their hospitality.
As mentioned in the first installment, we cannot list all of the
many persons who have helped us in the field, the herbaria, and
in the office, and who have sent us specimens and information.
We must, however, express our special appreciation to Mrs.
Lenore Smith for typing first drafts of most of the manuscript
from difficult handwritten copy, on a strictly volunteer basis.
The untimely death of one of us. Dr. Sachet, in the middle of
preparation of this installment, has slowed down the appear-
ance of the work, and lowered the precision of references and
proof-reading very seriously, though we have tried to live up to
her standards as best we could.
We must acknowledge indebtedness for taxonomic help
from the monumental Flora Malesiapa, of Professor C.G.G.J.
van Steenis, and from many revisions and monographs of
difficult groups published in the journal Blumea under his
editorship. We also have continued to benefit from the
bibliographic work of Mrs. M.-J. van Steenis-Kruseman and
William T. Steam (1954), F.A. Stafleu (1967), F.A. Stafleu and
R.S. Cowan (1976 et seq.), and also the Flora Malesiana
Bulletin. In these works exact dates of publication of a great
many works are established, interpreted, or clarified. Dr. Alwyn
Gentry kindly looked over the manuscript of Bignoniaceae and
made valuable suggestions.
Besides our own field work, the greater part of our
information on the morphology, occurrence, distribution, and
ethnobotany has come from herbarium specimens and their
labels. Too seldom is appreciation expressed to the numerous
collectors who have provided this vast store of data for use by
their successors. We are glad to offer our thanks to them.

SMITHSONIAN CONTRIBUTIONS TO BOTANY
In the paragraph headed “Uses” under the various species,
we have, where the material was not too verbose, copied more
or less verbatim from field labels, field notes, published articles
and books, but have used quotation marks only where they
seem useful to clarify the source of the information. The
sources are always provided, except in cases where the
information is from our own personal knowledge.
Vernacular names are copied exactly from published
sources, herbarium labels, and field notes, as we realize that
many are different renderings of the same names, as heard by
people of different linguistic backgrounds and experience. This
necessesarily results in more repetition. Sources are always
given, and specimens cited where possible, but the interpreta-
tion is left to the reader, who may understand such things better
than we can.
Bignoniaceae
Trees, shrubs, and lianas, rarely herbaceous; leaves opposite
or whorled, rarely alternate, compound or rarely simple or
unifoliolate, exstipulate but often with stipule-like prophylls
called pseudostipules; inflorescence cymose or racemose,
rarely much reduced and then borne on trunk or larger
branches; calyx gamosepalous; corolla gamopetalous, usually
zygomorphic and bilabiate, usually 5-lobed, lobes usually
imbricate in bud; stamens usually 4 with one staminode,
inserted on corolla, rarely 2, with or without 3 staminodes,
anthers usually 2-celled, the cells often one above the other;
ovary superior, 1- or usually 2-celled, placentation axile or, in
unilocular ovaries, parietal, style 1, stigma bilobed; fruit a
2-valved capsule or indehiscent, then large and fleshy or hard
with fleshy pulp; seeds often winged.
A large, mostly tropical family with many ornamental
cultivated genera.
The climbing genera are taxonomically difficult, some of
them based on what seem to be very inconsequential or
inconstant characters. Possibly too many genera are main-
tained. We are not prepared to rearrange them, however, and
are generally following the identifications by Dr. Alwyn
Gentry in various papers and in herbaria. Our key to these
genera has been greatly improved by suggestions from Dr.
Gentry.

large, inflorescence a long peduncled open panicle, pendulous;
flowers large, calyx 2(-5) lobed, 5 ribbed, campanulate;
corolla bilabiate, tube short, throat campanulate, curved,

As many as 18 species have been described in this
widespread African genus. Various authors disagree on how
many there are and how they are distinguished. At least two
species exist, one maroon- and one yellow-flowered (fide
Gentry in litt.). The widespread cultivated species has been
called K. africana and K. pinnata. Perhaps two species are
involved, as different looking individuals are seen in cultiva-
tion, but the maroon-flowered plants show no taxomonically
recognizable differances in Africa (fide Gentry). Most herbar-
ium specimens are too poor to help much. Van Steenis (loc.
cit.), has concluded that the genus has only one variable
species. Until more reliable information is available, we choose
to follow him and call the famous “sausage tree” Kigelia
africana.
It is said to have been planted in Guam, but we have seen no
specimens from there. It will doubtless be planted in
Micronesia if it has not already been.

Tecomaria (Endlicher) Spach
Tecomaria (Endlicher) Spach, Hist. Nat. Veg. Phan., 9:137, 1840.
Shrubs, sometimes somewhat scandent, much branched;
leaves pinnate, leaflets 5-9, variable in shape, ovate to elliptic
or rhombic or ovate, serrate; flowers in racemes or racemose
panicles; calyx narrowly cylindro-campanulate, lobed; corolla
slenderly tubular dilated somewhat, distally, bilabiate; stamens
4, exserted, style more exserted; capsule linear, slightly carinate
laterally, dehiscent perpendicularly to septum; seeds winged.
A small genus usually restricted to one or two spe-
cies,endemic to Africa. However, several Andean American
species usually referred to Tecoma strongly resemble the
African plants and have been transferred to it. Examination of
these tends to confirm the impression of similarity. If these are
considered too close to Tecoma, then perhaps the African ones
should go here, too. For the present we retain Tecomaria as a
separate genus.

Thick-stemmed shrub to 2-3 m tall, young stems fistulose,
squarish, tawny tomentose or lanate, glabrate when older, to 3
cm thick when mature; leaves large, subentire, to 40 x 20 cm,
petioles and veins beneath puberulent to tomentose to lanate,

flowers bisexual, bracts lanceolate, 2 x 0.5 cm, deciduous;
calyx to 12 mm long, irregularly cut about half-way into
triangular acuminate lobes, densely pilose externally, glabrous
within, only slightly accrescent, falling from maturing fruit;
corolla white, about 15 mm long, funnelform, densely pilose
without, throat pilose within, lobes 5, thick, ovate-triangular
glabrous within, equal, about 'A the length of the corolla;
stamens 3-7, anthers separate, all fertile; ovary glabrous,
falsely 2-celled; fruit fleshy, white, broadly ovoid, 15x10 mm.
fleshy style-base persisting as a beak; seeds many, brown,
broadly fusiform, foveolate.
Endemic to the limestone islands of Palau in wet forest,
growing in crevices with very little soil.
The actinomorphic corolla and 4-7 free stamens led
Hosokawa to propose the genus Protocyriandra for this
species, but because these characters appear separately in other
unrelated species, this genus, though discussed, has not usually
been accepted (Gillett, 1970). Although this species shares the
unusual actinomorphic corolla with C. palawensis, the two do
not seem closely related. The latter species has the usual
androecium of 2 stamens with coherent anthers, plus 3
staminodes.

glabrous; fruit ovoid, to 1.5 cm long, beaked, its base
surrounded by the prominent cup-shaped disk; seeds ovoid-
fusiform, longitudinally striate.
Found only in wet montane forests of Ponape and Kusaie, in
the eastern Carolines.
Type of C. urvitlei was collected on Kusaie by Dumont
d’Urville, but we did not locate it in the de Candolle herbarium
in Geneva in 1954; it is probably in Paris.
Kanehira cited his 831, 1606, 1642, and 1550, from Ponape,
which would be syntypes of C. ponapensis. No lectotype has
been chosen. We have seen 3 of these at FU.

cultivated in Philippines said to have been brought from
Temate, in the Moluccas.
In Micronesia occasionally planted as an ornamental; when
sterile easily confused with Pseuderanthemum carruthersii var.
atropurpureutn, but distinguishable by the pale stems not
marked by conspicuous white lenticels, and usually by the pale
blotching along the midrib of the leaf blade.

Nov. Act. Acad. Natur. Cur., 70:203, t. 10, 1897].
Herb to 2 dm tall, slightly decumbent at base, rooting at
lowest nodes, leaves somewhat crowded at base of plant, stems
retrorse pubescent rarely densely so and “tomentulose”; leaves
narrowly elliptic or elliptic-lanceolate, to 10 x 1.5 cm, apex
bluntly acute or slightly acuminate, base acute, margin
undulate, blade sparsely pubescent above and beneath, with
abundant linear cystoliths above, main veins about 5 on a side,
network obscure, petiole slender, 5-12 mm long; spikes
(racemes) slender, 1-8 cm long, sparsely flowered, 2 flowers in
most bract axils, bracts linear-lanceolate or lanceolate, mostly
about 1 cm long, lowest to 1.5 cm, apex blunt, not at all
imbricate; flowers shortly pedicellate to almost sessile; calyx
lobes tending to be coherent at first in lower half, narrowly
lanceolate-attenuate, about 7-8 (-10) mm long, subglabrous,
margins somewhat scarious; corolla about 12-15 mm long,
funnel form, white with maroon spot in throat, lobes somewhat
spreading, orbicular-obovate; stamens well included; capsule
narrowly fusiform, 7-8 (-12) mm long, containing 6-8 (-15?)
seeds, these 1 mm diam., dark brownish.
Apparently endemic to Palau, judging by the the rather
uniform series of specimens from there. This was at first
referred by us to H. anguslifolia Hallier f, on the basis of
similarity to the Amboina specimen so determined by Merrill.
Comparison with Hallier’s illustration, however, shows that it
differs in leaf outline, in the lax inflorescence and in the linear
bracts. It is closer to, but not identical with, Hallier’s
illustration of his H. stenophylla, of Celebes.

Herb with decumbent stems, rooting at lower nodes, distal
parts ascending, somewhat to strongly pubescent; leaves up to
8x4 cm, usually much smaller, from suborbicular to broadly
ovate, oblong, or elliptic, extremely variable even on same
plant, apex rounded to obtuse, or bluntly acute, base acute to
rounded or even subcordate, margins sub-entire or undulate to
crenate, blade with abundant linear cystoliths, from almost
glabrous to sparsely pubescent, more densely so beneath,
petioles usually more or less pilose, 1-3 (-4.5) cm long; spikes
pedunculate, usually 2-5 cm, but reaching 9 cm, fertile part
1-5 cm, rarely branched, loosely flowered, bracts longer at
lower nodes, up to 1.5 (-2?) cm long, these petiolate, clawed or
spatulate, blade ovate to obovate, decurrent on petiole, upper
ones less to not at all petiolate, ciliate; flowers 1 or usually 2 in
the axil of a bract, if 2, appearing to be one outside the other on
the petiole base, which is at 90° to the rachis, then curved
abruptly upward; calyx lobes lightly coherent in basal half,
separating, narrowly lanceolate long attenuate at apex, 7-10
(-13) mm long, almost glabrous or very slightly strigose or
ciliate in free distal part to sparsely but conspicuously ciliate
with long spreading hairs; corolla tubular at base, funnelform,
about 15 mm long, lobes somewhat spreading, round or
obovate, minutely puberulent on outside, white to lavender;
stamens included; capsule 4-sided, lanceolate, 8-9 mm long,
about 12 seeds, these discoid slightly oblique or subreniform,
sides smooth, brown, becoming almost black, 1-1.2 mm
across, hilum white.
This is an extremely variable species, with more or less
distinguishable local populations, not named here because of
lack of sufficient material and lack of understanding of the
variation outside Micronesia. Some of these have been given
names but are inadequately characterized and seemingly do not
32

have definite geographic ranges. A variant in Palau has been
described as Hemigraphis pacifica Hosokawa. Although the
leaves on the type collection are more acute than is common in
this species we cannot correlate this leaf shape with other
characters. A similar shape seems to be found occasionally in
Melanesian collections, and it is possible that intensive
biosystematic studies of H. reptans might show that it has some
significance.
At present we can only suggest several tendencies that seem
to be related to geography. Marshall and Gilbert Islands
collections have consistently smaller leaves, ranging from
almost orbicular to, when well developed, broadly oblong, or
oval, rarely elliptic, ordinarily not larger than 3x2 cm, plant
commonly rather pubescent.
Plants from the western Carolines (Palau) and Kapinga-
marangi, have larger leaves, up to 6 x 4 cm, and more elliptic
than oblong, less pubescent than material from the Marshalls.
The type of H. pacifica, Hosokawa 7400, fits here except that
it has leaves to 10x4 cm, acute, with margins more crenate
than usual. Two collections from Palau, Fosherg 32028 and
Hosokawa 9294, differ in having the leaves unusually pale
beneath and calyx lobes about 13 mm long, while in most
specimens they are 7-10 mm.
A single Guam collection, Fosberg 35620, growing as a
weed in nursury pots, has large thin, oblong leaves with
subcordate bases, undulate margins, and veins pubescent
beneath, unusually long peduncles but very short spikes, and a
very short corolla with anther tips exserted. Its calyx lobes are
not as attenuate as usual in this species. It is the only collection
from the Marianas, and might be a weed from anywhere.

above nodes; leaves ovate, to 7 cm long, 1.5-3 cm wide, apex
bluntly acute to somewhat acuminate, base acute to obtuse,
thin, softly appressed pilose especially along nerves, on slender
petioles up to 2 rarely 3 or even 4 cm long; flowers in spikes,
these 1-3 at terminal node and on ends of short lateral
branches, up to 15 cm long, nodding to drooping, with 4 ranks
of thin broadly ovate subacute, subcordate overlapping bronze
to roseate bracts, softly pilose above and on nerves beneath,
bracteoles similar but much smaller and narrower, pale, a pair
enclosing the base of each flower; calyx lobes broadly
lanceolate, acuminate aristate, pilose, pale green; corolla
tubular, white, softly pilose without, glabrous within, almost
straight, base of tube swollen or ventricose, distal third divided
into 2 narrow lips, the upper erect, shortly bifid, sub-galeate or
hooked, lower cuneate, straight, divergent at a small angle from
tube, shortly trilobed, lobes ovate, rounded at apex, palate
elongate, deeply plicate, broadly cross-banded with purple,
swollen base filled with gummy clear nectar; stamens with
stout, stiff white filiments attached about half-way up tube,
straight, with deep purple anthers, the 2 cells strongly offset,
basely exserted; ovary subglobose, style capillary, with
beard-like globules of nectar, stigma minute, punctiform, one
lobe scarcely developed; capsule squarish-ovoid, pilosulose,
thin walled, on a broad stipe, apex acute, retinacula spoon-
shaped.
This species, usually placed in the segregate genus Beloper-
one, when put in Justicia has been called Justicia fulvicoma, a
principally Mexican species, with short erect spikes and narrow
bracts. The two seem to be sufficiently different to be
maintained. We have not seen seeds on the cultivated
specimens studied. Though known from Guam, Kwajalein,
Jaluit, and Nauru, we have only seen specimens from Nauru,
one of which has pale canary yellow bracts {Fosberg 58721)
and may be the cultivar “yellow queen,” though the bracts of
that are said to be chartreuse-green. This plant is known in
Nauru as “yellow shrimp-plant.”

to rounded, often slightly decurrent, veins visible but not
prominent, petiole short, to 1.5 or 2 cm; thyrses narrow, with
basal branches usually somewhat more developed than above,
thyrses frequently paniculately arranged at the ends of
branches, glabrous or obscurely puberulent, bracts reduced to

Plant described originally from Erromanga, New Hebrides
(type McGillivray s.n. (K)), not known with certainty in wild
state, possibly native in Melanesia; somewhat similar plants are
known wild in the New Hebrides. A number of varieties are
widely planted as ornamentals in many tropical countries and
islands. These are usually treated as species, but the differences
between them are slight, mostly in color patterns in leaves and
flowers. At least three distinguishable ones are known in
Micronesia. They are here treated as varieties, because nothing
is known of their origins. They could equally well be called
cultivars.

mm thick, only very slightly ampliate upward, lobes 10-15
mm long, obovate to broadly elliptic, patent to slightly
reflexed; glabrous; anthers about 2 mm long, narrowly oblong,
shortly exserted on curved glabrous filaments; style filiform,
glabrous, about 25 mm long, stigma subcapitate, bilobed,

on small side branchlets, rhachis 4-6 cm long, occasionally
branched, bracts small, ovate, about 1 mm long, subtending
pedicels 2-3 mm long, dilated upward, occurring opposite or
subopposite moderately spaced along rachis; sepals narrowly
lanceolate, 3-4 mm long, free almost to base, almost glabrous,
sharply pointed; corolla about 2 cm long, curved, glabrous
without, limb in bud 3-4 mm long (buds only seen), style and
stigma about 3 cm long (only detached ones seen intact); fruit
glabrous, about 2 cm long, stipitate basal portion 1 cm, beak
short; seed disk-like, margin scalloped, lobe at one end of scar
more prominent, faces conspicuously warty, gray-brown, 3-4
mm across.
This is quite distinct from Pseuderanthemum inclusum in its
leaf shape, more slender and lax inflorescences, much longer
corollas, styles and stamens, and in its scalloped warty seeds. It
seems closest to Philippine plants commonly referred to
Pseuderanthemum hicolor (Schrank) Radlkofer, which has
predominantly axillary cymes, linear subulate bracts and
sepals, and entire-margined seeds.

determined by him as R. repens differs in having longer
petioles, pustulate hairs on leaf midribs, broader, more
acuminate leaf blades, and shortly pedunculate axillary spikes
to 10 nodes long, without flowers or fruit. It is obviously
something else but has not been recollected. The record of
Ruellia repens, in Kanehira’s Enumeration (1935:413-414), is
based entirely on this collection, so the species should be
deleted from the recorded flora of Saipan, as was done in our

A pan-tropical cultivated ornamental, sometimes prersisting
after cultivation; both color forms, mauve and white, are
present in Guam. The plant seems to be of Indian origin and in
Micronesia is known from Guam and Palau. Two varieties,
often distinguished as species, are found in Micronesia.
Thunbergia grandiflora (Roxburgh ex Rottler)
Roxburgh var. grandiflora
The typical variety, with broad leaves, is known from both
Guam and Palau. On Guam, at least in the Barrigada area, it
presents the appearance of being spontaneous in roadside
thickets, but is doubtless merely persisting from former
plantings. This colony is of the white-flowered form, and is
quite conspicuous, climbing over small trees.

Differs from var. grandiflora principally in the narrower,
3-7 cm wide, ovate to oblong, rarely lobed but frequently very
coarsely repand-serrate leaves, acuminate at apex, usually
shorter petioles and more slender, often shorter pedicels, often
more congested racemes.
The narrower leaves give a somewhat different aspect to the
plant, but there is scarcely a break between the two varieties.

either in width or margin. The flowers seem practically
identical. The spurs or hom-like processes on the bases of the
anthers seem longer in var. laurifolia, but we have not been
able to confirm the presence of the small spinules at the bases
of these processes mentioned in some accounts. Because we
have not seen capsules on either variety we can say nothing of
the presence or absence of puberulence.
Var. laurifolia is known in Micronesia only from Guam.

Glabrous shrub, to 1.5 m tall, usually lower, prostrate in
exposed places, branchlets finely punctate, leaves scattered,
fleshy, narrowly obovate, at most 5 x 1.5 cm, apex rounded to
acutish or slightly short acuminate, base attenuate-cuneate into
a short petiole, obscurely serrate toward apex, obsurely
punctate glandular on both sides, rugulose when dry; flowers
on axillary pedicels about 1 cm long, 1-3 in an axil, sepals
ovate, acute, to only slightly acuminate, not ciliolate, tending to
be somewhat concave or inrolled, somewhat puncticulate, 1.5
mm long, corolla campanulate, 3 mm long, 6 mm wide when
fully mature, when lobes are not reflexed the whole corolla may
be 4-5 mm long, lobes 5, ovate-rounded, throat glabrous at
base, white, somewhat punctate, stamens 4, inserted near base
of corolla, included, anthers orbicular-horseshoe shaped; style
about 2 mm long, stigma sub-trilobate; fruit globose about 4
mm across, dark purplish red when ripe, stone depressed
globose, about 3 mm wide, acuminate at top, at base, with 4
keels from center of base about ^3 the way to the summit,
intervals between keels convex.
This has been referred to the New Caledonian M. tenuifolium
Forster f. by some earlier writers. It is indeed closely allied to
that species. It differs in leaves being obovate, tending to be
obtuse and fleshy, with venation not obvious when dry, rather
than elliptic-lanceolate acuminate, and in the acute inrolled
glabrous sepals rather than acuminate flat ciliolate ones. These
differences are not very impressive, but in a genus as difficult
as Myoporum these species seem about as well separated as
most. Together with the great geographic separation the
differences seem to justify recognition of the Bonin-Marianas
plant as a distinct species.
In the Marianas it is found on Pagan, Saipan, Tinian, Rota,
and Guam, on low cliff tops above the ocean, at least usually on
limestone. The Moore 477 collection is the first record from
Guam. The species was originally described from Chichi Jima,
in the Bonin Islands. In the Marianas it is not common, but may
be found especially on terraces and cliff tops facing the sea at
rather low elevations.

fertile branches, bracts small and scale-like; calyx a collar or
cup with 5 dentiform lobes; corolla hypocrateriform, lobes 5,
imbricate and somewhat sinistrorsely contorted; anthers ex-
serted from sinuses of corolla and deflexed, linear; stigma
tardily exserted, ovary cells 2, placentas attached to septum,
enlarging in fruit, ovules few to many; fruit baccate, globose,
5-10 mm diam, with thin flesh; seed angular rather few in a

A genus of a few (to many ?) species, extending from Africa
to the Pacific Islands, often considered a part of Randia sensu
lato. One species native in Micronesia.
A common lowland tree from southeast Asia and Malesia
eastward throughout most of the western Pacific Islands and at
least as far east as the Society Islands. In Micronesia on
practically all high islands and the atolls of the southern
Marshalls and northern Gilberts, but not recorded from the
Caroline atolls.

possibly sometimes terminal and becoming axillary, irregular
(2-) 3-5 times branched, branches and pedicels subtended by
scale-like bracts, ultimate branches either ending in a triad of
pedicellate flowers or proliferating and elongating, leaving
naked pseudo-rhachises with scale-like bracts and occasional
fruits, flowers pedicellate, hypanthum glabrous, narrow to
cup-shaped, crowned by a spreading to funnelform calyx collar,
minutely denticulate, corolla white with a short tube, 3-5 mm
long, lobes 5, narrowly oblong, reflexed, apex rounded,
mucronate or not, throat stiffly bearded; anthers completely
exserted, linear, 9-10 mm long, tending to twist distally;
stigma and part of glabrous style exserted, stigma about 1 cm
long, tending to be curved, somewhat thickened, not bifid, apex
bluntish-pointed; fruit red to black, pea-like, crowned with
persistent calyx collar. Seeds not very numerous, embedded in
pulp, irregularly angular, angles tending to be thin and
wing-like.
Tirvengadum (pers. comm., 1988) considers the Pacific
Islands Aidia populations to be distinct from those of Vietnam,
and proposes to use the name Aidia racemosa (Cavanillas)
Tirvengadum for the Pacific plant. Comparison of a series of
Pacific and especially Micronesian specimens with a series of
Asian ones, including some from Indo-China reveals a wide
variability in both series, but much overlap and no consistent
differences. Until a more convincing contrast is made, we
continue to use Aidia cochinchinensis in the present very broad
sense.
Occasional or locally common in low to mid-elevation forest
on high islands and wet atolls in Micronesia.
Uses. — Used for framework of roofs of native houses (de la
Corte, Guam Recorder, 1972). Used against fever (Marianas,
Fritz cited by Prowazek, 1913). Syphilis: Decoction of young
leaves of “kelmusu” is taken like tea (Palau: Okabe, 1941).
Beverage: Decoction of leaves is taken like tea (Palau: Okabe,
1941, 1943). Tuberculosis: Bark of “gasmatz,” “kureuebuh”
(skin of betelnut) and young sprouts of “buh” {Areca or
Schizostachym lima ?) are crushed together, and taken with
coconut milk (Yap: Okabe, 1943). “Used for namot tinino” a
kind of sickness.” (Source unknown.)

cm, mostly 5 veins on a side, apex abruptly shortly acuminate,
tip blunt, base acute to obtusely narrowed and slightly
decurrent to a short (3-8 mm) petiole; stipules triangular,
strongly acuminate, 3-6 mm long; cymes subsessile (peduncle
to 1-1.5 mm), 8-10-many-flowered, strongly condensed
(capitate or subcapitate) pedicels about 2 mm long at anthesis,
elongating to 5-6 mm in fmit, subtended by erose broad

mm long, corolla tube about 3.5 mm long, lobes ovate, about 2
mm long, throat barbate; fruit “rosarot,” obovoid, about 13x9
X 5 mm, not or scarcely sulcate nor emarginate.
All records of this variety are from Ponape, in spite of the
epithet korrorense, which clearly refers to Koror, Palau.
Valeton does not explain his choice of epithets.
Other varieties of this species are found in the South Pacific

Apparently very rare, only collected once; material exam-
ined is very inadequate and might almost as well belong to the
genus Cynochthodes.

strigulose beneath, apex bluntly acute or rounded at tip, rather
few veins on a side; panicle small to rather ample, rhachis of
4-7 intemodes, leaf-like bracts at lower nodes, densely
minutely appressed pubescent or tomentulose; calyx as broad
as high; corolla rose-pink externally, “shell-pink” on inner
surfaces of lobes; fruit ovoid, about 1 cm long or less, rarely
more.

Cinchona succirubra Pavon ex Klotsch, Abh. Akad. Berl., 1857:60, 1858. —
Mayo survey, m.s. 28, 1954.
Small to rather large tree, bark tending to turn reddish when
cut; leaves from broadly elliptic or oval to broadly oblong,
rather thin, conspicuously veined, somewhat pubescent be-
neath; flowers in large panicles, pink, fragrant; capsules ovoid
fusiform, 2-3 cm long, walls firm.
This species is doubtfully distinct from C. pubescens Vahl,
and by most modem authors merged with that species. That is
probably where it belongs, but until the varieties and synonyma
in that protean species, are properly sorted out, it seems more
convenient to maintain it as an admittedly weak species. It was
formerly widely planted for quinine production, but was not the
best species for that purpose. It is said to have been introduced
experimentally into Palau by the Japanese, but we have not
seen any Micronesian specimens.
Coffea L.
Cojfea L., Sp. PI., 172, 1753; Gen. PI., ed. 5, 1754.
Shmbs and small trees with (at least in our species)
dimorphic branching, with robust ascending shoots sending out
slender horizontal flowering branches with leaves pseudo-
distichously arranged; leaves opposite (or rarely temate),
pinnately net-veined; stipules persistent, entire, sheathing near
base, with axillary glandular trichomes (colleters); flowers
bisexual, borne in axillary cymes that may be variously
condensed, even to triads or solitary flowers, subtended by very
reduced foliar and stipular bractlets, these often subulate or
scale-like; calyx lobed, toothed or truncate; corolla salverform
or funnelform, 4-7-lobed, lobes patent, stamens the same
number as corolla lobes, attached in corolla-throat, included or
(in ours) well exserted; ovary 2-loculed, ovules 1 in a locule,
attached to the septum, style elongating during anthesis, stigma
bifid, exserted; fruit dry or (in ours) fleshy, 2 endocarps thin,
parchment-like with 2 large seeds, seed with a longitudinal
groove on inner face.
A genus of about 70 species of the Old-World Tropics,
mainly African. Several species are commercially important, 3
of these introduced in Micronesia.

Differing from D. repens especially in the glabrous
hypanthium and calyx; vegetative parts glabrous or sparsely
puberulent.
It is questionable whether this is to be treated as a species or
as a form of D. repens. In many places, including Guam, they
grow together. Until experimental evidence is available it
seems convenient to admit them as separate species. First
described from India.

Gardenia Ellis
Gardenia Ellis, Philos. Trans. R.S., 51:935, t. 23, 1761 [nom. cons.].
Small trees or shrubs, branchlets subterete; leaves opposite
or rarely whorled, entire, usually firm chartaceous, veins often
with domatia in axils below, petiolate to subsessile; stipules
sheathing, at least at base, where they are joined to the petioles,
in some species secreting a gum around terminal bud, unlobed
to deeply bilobed, or a single lobe, separating from attachment
by circumscissile dehiscence; flowers solitary, terminal, be-
coming pseudo-axillary by development of an axillary bud at
the terminal node; hypanthium turbinate or prismatic, at or
below the apex externally in some species developing 3-5
lobe-like “spurs” or appendages, flattened radially, alternating
with the placentae, persisting on the fruit; corolla hypocrateri-
form (at least in our species), tube usually at least slightly
dilated upward, bearing 6-9 lobes, imbricate and contorted
sinistrorsely in bud, spreading, very fragrant at anthesis;
anthers attached dorsally by very short filaments in corolla
throat, linear, tips exserted at anthesis; style slender-cylindric to
filiform, stigma fleshy, connate, tips slightly exserted, ovary
unilocular with 3 to 5 parietal placentae with many ovules in
vertical rows; fruit a large subglobose or prismatically angled
or alate “drupe” with a fleshy to fibrous-coriaceous mesocarp
and bony endocarp, the numerous seeds embedded in a pulpy
mass developed from the fleshy placentae; seed with testa
fleshy-papillate drying to a “scrobiculate” surface.
This description is partially adapted from the very ample one
by A.C. Smith (Am. Joum. Bot., 61:109-111, 1974), treating
the species of the Fiji area. Hence it may not be completely
applicable to all species in other tropical regions.

Shrub or rarely small tree, branchlets dark grayish brown,
weakly 4-angled, terminal buds gummy; leaves to 20 x 10 cm,
opposite, glossy green, obovate, rounded at apex or with a short
blunt umbo, contracted to somewhat cuneate at base, on
short-thickish petioles; stipules ovate, connate at base into a
very short sheath; pedicels 1-2 cm long, angled above,
hypanthium turbinate (3-) 4-5 angled, calyx short, broadly
campanulate, to 10 mm high with (3) 4 or 5 ovate to oblong,
acute to rounded appendages; corolla white, fading yellowish,
very fragrant, tube 3-4 cm long, somewhat ampliate to throat,
limb 4-6 or more cm wide, lobes 6-8, narrowly elliptic or
slightly obovate, spreading; anthers linear, partly exserted;
narrowly fusiform stigmatic mass partly exserted, acute; fruit
obovoid to ellipsoid, costate or angled, cultivated plants usually
not fruiting.
An attractive cultivated ornamental, native in Melanesia and
western Polynesia, highly prized and much cultivated in the
Society Islands, there called “Tiare Tahiti”; said to have been
introduced into Guam by Harold Mayo in late 1950, or early
1960s. In eastern Polynesia, Hawaii, and probably Micronesia
it seems never to set fruit. This may indicate that only a single
self-sterile clone is present, or that a suitable pollinator is
lacking.

fruit abundantly; young fruit globose, mature ones depressed
globose, drupaceous, flesh white, containing stiff fibers that
persist after flesh rots or is eaten by hermit crabs; stone corky,
floating, with 5 or 6 cells.
Uses. — Wood used as building material (Rota; Fosberg
24947). Cold: Leaves of “tifif’ {Alpinia carolinensis), of
“alphos” {Eugenia javanica), of “warao,” of “job” (Phymato-
des scolopendria or Angiopteris evectal), of “teribuk”
{Cheilanthes tenuifolia), and of “wararg” {Decaspermum
fruticosum) are mixed, with which the whole body, starting
with the head, is rubbed. Monthly troubles: Fruit, young leaves,
and bark of “warao” are crushed together and the sap is taken
(Yap: Okabe, 1943). Used as medicine; Branches have a
magical significance in treatment of swelling. Wood used in
paddles and construction. Used in garlands (Woleai: Alkire 39).
Useful for house frames, house posts, outrigger booms, and the
diagonal braces between the outrigger and the canoe hull.
When large, it is also used for canoe hulls. The leaves are
medicinal (Kili: Bikini people, St. John and Mason, 1953).
Provides wood for house frames, house posts, and the
construction of outrigger booms, and braces. The leaves were
valued for medicinal qualities and were part of the native
practitioners’ standard stock of remedies (Kili: Bikini people,
Kiste, 1968). The wood is used in houses for rafters and wall
frames, in canoes for hull and ribs. Formerly used in
fire-making by friction. Flowers are commonly used in making
garlands. Leaves are used as a fertilizer for babai and other
plants (Tarawa; Catala, 1957). Timber tree (Micronesia: Okabe,
1941). Wood for construction and implements. Root for shark
hooks. Flowers for leis. (Kapingamarangi: Niering, 1956).
Used for leis; leaves are spread on ground on which to dry
Pandanus pulp; skin of fruit emd Scaevola were said to cure
venereal disease. (Onotoa: Moul, 1957).
Usually regarded as a strand species, and very common
along Old World tropical shores, but also in places at
considerable elevations. In Micronesia upland occurrences are
frequent in the Marianas.

Glabrous slender woody climbing liana, tending to be
extensive, no strong odor noted; leaves opposite (no whorls
noted in Micronesian specimens), from elliptic to oblong or
almost orbicular, somewhat acuminate at apex, acutish at base,
up to 10 or more cm long, apparently glossy above, veins 4-8
on a side, petiole slender, 1-2 cm long; stipules sheathing,
forming a very low truncate collar, persistent; flowers mostly in
axillary loose clusters, rarely subcymose, or reduced to
fascicles or one or two flowers, rarely in terminal triads, rachis
with one or two nodes, the lower with usually 2 flowers or
branches that may bear one or several flowers, the upper
bearing a pseudo whorl, an umbel, or a pair of pedicels, these to
1 cm or more long, hypanthium urceolate; calyx very short,
subtruncate or slightly denticulate; corolla with (4 or) 5 lobes,
these valvate, much exceeding tube, tube to 4 mm, lobes to 7
mm, narrowly lanceolate, densely woolly within, bluntly
pointed; anthers 4-4.5 mm long, linear, slightly swollen at tips,
strongly exserted on glabrous filaments attached about 1 mm
NUMBER 81
63
from base of anther; style glabrous, exserted 3-4 mm, stigma
lobes blunt, about 4 mm long, stigmatic on inner sides, margins
slightly revolute; fruit a drupe up to 16 x 11 mm, ovoid to
subglobose, with 4 or 5 thin-walled stones, one or more usually
undeveloped, without a seed.
Plants from other parts of range, e.g., Samoa, are larger, have
fruits much larger than those in Micronesia, with all four stones
with developed seeds. Not enough fruiting Micronesian
specimens are available to tell if a different taxon is involved.
Gynochthodes trukensis and Micronesian plants, at least, of G.
verticillata, seem to fall within the range of variation of this
plastic species. Uncommon in volcanic and limestone areas in
open forest; not well known.

Leptopetalum Hooker and Arnott, Bot. Beechey Voy., 295, t. 61, 1841 [1838].
Habit various; leaves opposite (rarely whorled), entire;
stipules interpetiolar, low triangular to somewhat sheathing,
entire or pectinate; inflorescence axillary or terminal, cymose
or thyrsoid or flowers in close axillary verticels, pedunculate
heads, or glomerules, or solitary, flowers sessile or pedicellate,
usually 4-merous; corolla salverform to funnelform, rarely
almost rotate, tube short to somewhat elongate, cylindric,
dilated upward, or somewhat globose; stamens usually attached
below sinuses, rarely basal; style with 2 branches, stigmatic on
inner faces; fruit a capsule, globose, cup-shaped or somewhat
compressed, crowned by persistent calyx, disk flat or elevated,
dehiscence loculicidal, septicidal, or both, rarely indehiscent;
locules 2 with axile, more or less fleshy placentae covered by
seeds, these various, usually peltate or angular by compression,
rarely angles winged, hilum superficial, on a prominence, or in
a pit.
A very large pantropical and temperate genus, if accepted in
a broad sense as treated here, adapted to many and diverse
habitats. Many of the species are found in open, weedy or
savanna situations but some are plants of forests, especially
montane ones. The genus is well represented on islands,
especially in the tropics. Twenty seven species, some with
several varieties, are found in Micronesia, of which five or
possibly six may be introduced. Of the native ones, all but four
are endemic. Only one, Hedyotis hiflora, possibly an aboriginal
introduction, is found on low coral islands (as well as on high
islands).

Hedyotis aimiriiken.sis Kanehira, Trans. Nat. Hist. Soc. Formosa, 25:4,
1935. — Hatusima, Trans. Nat. Hist. Soc. Formosa, 26:225, 1936.
Shrub, stem unbranched to slightly branched, subglabrous,
about 1 m or more tall, when branched decussately so,
intemodes 4-6 cm long; leaves petiolate, chartaceous, olive-
green, concolorous when dry, ovate-oblong to oblong, to 9 x 4
cm, apex obtuse to very shortly acuminate at apex, obtuse to
subtruncate at base abruptly attenuate to a flattened petiole 7-9
mm long; stipules broadly ovate, entire to irregularly lobed,
lobes linear; panicles terminal and axillary, up to 12 cm long,
decussately branched, leaves grading smaller into bracts and to
linear bractlets 4-5 mm long; calyx tube (hypanthium)
obconic, glabrous, lobes linear-lanceolate, acuminate, 2-3 mm
long scarcely 0.5 mm wide; “capitulis” (= capsules)] stipitate,
oblong about 3 mm long, thickly coriaceous, septicidally
bilocular; seeds 2 in each locule, angulate (roughly translated
from Kanehira).
Kanehira says apparently allied to Hedyotis korrorensis, but
it differs by its petioled leaves with subtruncate base and nearly
horizontally divaricating branched panicles and somewhat
longer pedicels.
Hatusima reduces this outright to H. korrorensis, but the
photo shows a plant with quite different inflorescence, and
Kanehira’s description mentions this difference. We have not
seen the type, Kanehira’s #2369, from Aimiriik, and no other
material has, to our knowledge, been referred to this species.
Thus it is, if maintained, a local endemic to Aimiriik, in
southwestern Babeldaob.
For the time being, until more material becomes available,
we will maintain it as a member of the H. fruticulosa group.

Young growth and usually under-sides of leaves spreading
pilose or villous, leaves usually elliptic, about 5x2 cm, slightly
or not acuminate, abruptly mucronate, petioles 5 mm or less;
stipules low, triangular, pectinate with 5 (-7) very unequal
pilose setae, the central one longer; cymes dense, axillary,
rather few flowered; calyx lobes pilose, linear-lanceolate,
persistent; corolla campanulate, lobes and tube subequal, lobes
oblong-ovate; capsule indehiscent, nut-like, globose, 1.5 mm
long, rugose, hard, crowned by calyx lobes; seed blackish,
pe 1 tate - tetrahedral .
Ecology and geographical distribution: Growing in forest, or
in semi-cultivated forest around dwellings, at 10-15 m
elevation, in Yap and Palau. Similar forms, with smaller, less
acuminate leaves and more abundant pubescence, are found
from southeast Asia to India and Ceylon. First reported from
Yap by Volkens.

accrescent in fruit; corolla white, broadly tubular, about 2-3
mm long, lobes ovate, about 1 mm long, slightly spreading,
tube sometimes swollen, the whole thin and readily caducous,
usually lacking from specimens, throat in some with tufts of
hair; anthers subsessile in throat; style subequal with tube,
bifid, glabrous; fruit subglobose, slightly compressed, about

Widely distributed from south Asia to Micronesia and
western Polynesia in disturbed or weedy habitats, its pre-
human range uncertain; obviously spread by human activities.
An extremely variable species, but clear geographic or
ecological varieties difficult to establish. Further field study
would be desirable.
Uses. — The leaves may be chewed, then the juice spit into
the mouth of a baby to keep the baby strong. The chewed leaves
are then spread on the joints and the lower back to make the
baby strong (Sonsorol, Berry 109). Ingredient in medicine
(Woleai, Alkire 57).

thin, united, funnelform, 8-10 mm long, margins densely
pectinate with strong, bristle-covered setae about 4 mm long,
persistent (in Takamatsu 1277 neither persistent nor bristly),
stipules becoming distended by developing axillary heads of
flowers and fruits, finally splitting and shrivelling; axillary
heads densely many-flowered, hirsute (except in Takamatsu
1277)-, calyx and hypanthium shortly hirsute, calyx lobes
linear-lanceolate acuminate; corolla funnel-form, 4-5 mm
long, glabrous without, villous within, lobes 1.5 mm long,
oblong-ovate; anthers linear-oblong, 1.2- 1.5 mm long, dorsi-
fixed on short filaments, conspicuously exserted, erect;
capsules obovoid, hirsute, about 3 mm long, deeply septicidally
dehicent, then shallowly loculicidal; seeds dull blackish,
suborbicular, peltate, basally substipitate, about 0.6 mm
diameter.
This species is closely related to H. macrophylla Wallich of
south and southeast Asia and H. platyphylla Merrill of Borneo.
It is, so far as known, endemic to the volcanic parts of
Babeldoab, Palau, where it grows in dense forests.

Erect shrub, stems, leaves and stipules glabrous, stem
somewhat squarish, internodes to 4 cm long; leaves elliptic, to
10 X 4 cm, firm chartaceous, apex slightly acuminate, base
narrowed to a very short petiole, veins not prominent, 5 or 6 on
a side; stipules broadly low triangular, pectinate with 5 to 7
linear gland-tipped processes, the middle one twice the length
of the others; inflorescences axillary thyroid 3-5.5 cm long,
subtended by reduced leaves or bracts to 6 cm long, peduncle
moderately strong, stiff, spreading slightly ascending, upper
part closely divaricately ramified, 2 internodes above peduncle,
branches ending in globose glomerules, small ovate bractlets at
bark of branches; inflorescence branches and glomerules
sparsely hirtellous, calyx lobes oblong acute 1.5-2 mm long,
recurved, persistent; “flowers violet”; capsules depressed
globose, 2 X 2.5 mm, sparsely hirtellous, septicidally dehiscent;
seeds peltate, orbicular to somewhat pentagonal, 0.7-0. 9 mm
across, black, reticulate, attachment on a low prominence.
This species known only from the type, seems to be rather
intermediate between H. tuyamae and H. divaricata, also close
to H. fruticulosa, from which it differs in its small, strictly
axillary inflorescences.
It is named for Mrs. Marjorie Vemita Cushing Falanruw,
eminent naturalist and self-taught ecologist, of Yap Island,
collector of the type and many other important plant specimens
in Micronesia.

Slender erect shrub (or scandent?), glabrous, branched
above, branchlets somewhat squarish but not angled, inter-
nodes 2-5 (-9) cm long; leaves, ovate to elliptic 3-10 cm
long, 2-4.5 cm wide, apex acute to acuminate, base obtuse to

petiole slender 8-20 mm long; stipules rounded to triangular,
adnate to bases of petioles, pectinate, setiform processes at least
somewhat unequal, 5 to 7; cymes axillary, open, slender, up to
6-8 times divaricately branching, in each forking a sessile to
distinctly pedicellate flower or fruit, 1-2-5 flowers at
terminations; calyx united and cup-like at base, lobes ovate to
triangular, firm, ciliate or glabrous, persisting; corolla 3.25 mm
long, funnelform, lobes oblong to ovate, equalling tube, throat
bearded; anthers sessile, included or slightly protruding; style
equalling anthers, stigma capitate; capsule subglobose or
globose, 2.5 mm long, septicidally completely separating,
valves slightly loculicidally splitting; seeds dark brown to
black, 0.6-0.8 mm across, subangularly peltate, slightly
convex above, with a wedge-shaped base, surface prominently
cellular-reticulate.
This is a rare species that has not shown up in recent Palau
collections. It is undoubtedly close to H. schlechteri (Valeton)
Merrill & Perry, as noted by Valeton. Two varieties are
apparent, both probably confined to old volcanic soils.

Plant slender, glabrous, possibly shrubby? or sub-scandent,
intemodes to 6.5 m long, slightly squarish; leaves elliptic, to
6.5 X 2 cm, those subtending inflorescences much smaller,
somewhat acuminate, base narrowed to a slender petiole less
than 1 cm long; stipules low triangular, with a long central
tooth and 2 much smaller ones on each side; inflorescences
axillary, very slender, thyrsoid with slender peduncle about half
total length of thyrse, rhachis with 2 or 3 intemodes, each
branch with a shortly pedicellate flower, and 2 lateral branches
that again branch, branchlets ending in a triad with central
pedicel short, at base of each peduncle is a tiny dwarfed branch,
ending in a triad or cymule; calyx lobes lanceolate, more or less
recurved, persistent; capsules globose, 2 mm diameter, septi-
cidal, valves splitting somewhat loculicidally.
This plant, represented only by a slender branchlet, seems to
belong with H. divaricata but lacks the elongate zigzag
inflorescence branches and has narrower, elliptic leaves, and
rhachises with 2 or 3 intemodes. Its leaves more resemble those
of H. cushingiae, to which one might assign it as a variety with
an open inflorescence. Indications of affinities in this group are
not to be taken very seriously.

upward, 10-25 or even 45 cm long, 5-10 cm wide, branches
subtended by foliaceous bracts on rhachis, ramified 2-3 times,
a shortly pedicellate or subsessile flower frequently found in
forkings, ultimate branchlets ending in a triad or small
glomerule or even {Posher g 46310) in dense heads, rarely
(Falanruw 3202) the branchlets puberulent, or with only traces
of puberulence; flowers subsessile or very shortly pedicellate,
hypanthium turbinate, calyx lobes ovate to oblong, 1.5-2 mm
long, bluntly acute, persistent and elongating slightly and
becoming recurved in fruit; corolla 3.5-5 mm long, lilac or
purplish, funnelform, glabrous without, lobes ovate, 1.5 mm
long, densely woolly within; anthers included or slightly
exserted (Valeton); capsule globose or slightly depressed-
globose, dehiscing septicidally into 2 coccus-like valves, these
dehiscing slightly loculicidally; seeds black, peltate, 0.5-0.7
mm across, roughly orbicular or oblong, reticulate, attachment
on a ventral wedge-shaped prominence.
This species is probably endemic on Yap, though it has been
reported to occur on Guam (Merrill, 1919; Stone, 1971) and on
Palau (Okabe, 1941; Kanehira, 1935; Otobed, 1967; Fosberg et
al., 1980). We doubt its occurrence in either place. Marianas
specimens thus determined have turned out to be H. laciniata
Kanehira. Palau specimens seem to be either H. tuyamae
Hosokawa or H. korrorensis (Valeton) Kanehira. Its principal
habitat seems to be in savanna and disturbed areas.

Robust erect herb, to 1 m tall, stem squarish, sulcate when
dry, intemodes of main stem to 6.5 cm long, glabrous; leaves
elliptic to oblong, blades to about 16 x 7.5 cm, firm-
chartaceous, glabrous, bluntly acuminate, base narrowing and

Kanehira 1230, which we have not seen. The Falanruw
collection matches fairly well, but the glomerules are not as
open as described for the type.
The few characters in which it differs from vax. fruticulosa
do not seem sufficient for more than varietal status.

Hedyotis mariannensis sensu Kanehira, 1935 [pro parte; non Merrill, Philip.
Journ. Sci. Bot., 9:144-145, 1914],
Dwarf shrub, 40-50 m tall, stems somewhat 4-angled,
glabrous; leaves lanceolate, to 7 x 1,7 cm, apices somewhat
acuminate, base attenuate, subsessile, or decurrent on a short
petiole, blade thin, glabrous, veins obscure, 3 or 4 very strongly
ascending on a side; stipules very short triangular acuminate,
adnate to petiole bases, near apex obscurely glandular
denticulate, with a slight submarginal flange; cymes 3 at
terminal node, umbelloid, branches 4 or 5, each branch ending
in a triad or again umbelloid; flowers shortly pedicellate, bracts
and bracteoles much reduced, triangular subulate: calyx with 4
triangular teeth, 1.5 mm long; corolla white, broadly fun-
nelform or funnelform-rotate, 4 mm long and wide, tube 2 mm,
throat glabrous, lobes ovate-oblong, apex acuminate, spread-
ing; stamens inserted at base of corolla, anthers included, 1.5
mm long, dorsi-fixed; style “subclavatus” 5-6 mm long;
capsule broadly ovoid, sides slightly sulcate along septum,
walls firm, disk somewhat elevated and compressed, dehis-
cence loculididal across disk, valves slightly emarginate; seeds
“minuta angulata, testa reticulato-punctata”; not seen.
This species superficially resembles H.foetida but may not
be really very close. Its capsules are larger, thicker-walled, and
differently shaped, and the inflorescence is smaller and much
less complicated. We have not seen the type, Kanehira 2181,
from the Marianas Islands, Alamagan Island, where it is
apparently endemic.

Two varieties were distinguished by Valeton, one glabrous,
the other softly puberulent or hirtellous. To these may be added
one that is glabrous but has the flowers in conspicuous
subumbelloid glomerules, and another that has even more
contracted, almost subcapitate hirtellous glomerules. We have
not seen the type of var. mollis, but as described it seems
distinguishable.
The entire species seems confined to the volcanic parts of

weaken these varieties, but they seem worth calling attention
to. They may be separated by the following key.

Hedyotis korrorensis var. hosokawana Fosberg
Hedyotis korrorensis var. hosokawana Fosberg, Allertonia, 6:230, 1991.
Dwarf shrub to 50 cm tall, unusually densely branching in
habit, short intemodes, lacerate hispidulous stipules, dome-
shaped inflorescence, and hispidulous glomerules.
Tentatively placed here in spite of the lacerate stipules and
hispidulous glomerules because it agrees in most other respects
with H. korrorensis. It was at first thought to be var. mollis.
Known only from the type.

Oldenlandia korrorensis var. mollis Valeton, Bot. Jahrb., 63:295, 1930.
Differs from var. korrorensis in being softly puberulent.
The type of this is from Palau, Koror, Raymundus 208, which
we have not seen; probably lost in the bombing of Berlin.
This cannot be very common, as we have not found anything
corresponding to it in the rather abundant material of this
species that we have examined excepting the Hosokawa
specimen cited below.

panicle-branches condensed into globose subglomerate um-
bels.
This plant, though not geographically separated, stands out
as so distinct in appearance that it is described as a variety. The
collector says it is common, but he may have been referring to
the common var. korrorensis.

spreading, strongly recurved, base forming a neck, or scarcely
so, crowned with curved lobes; corolla funnelform-
campanulate, tube subequal with calyx, throat somewhat or not
exserted, lobes ovate, recurved; anthers sessile in throat, style
and stigma about equalling anthers, or longer; fruit globose,
thin-walled, strongly septicidal, the two halves separating,
hemispherical, almost closed by the split halves of the septum;
seed peltate suborbicular, blackish, 0.7-0.8 mm wide, with a
prominent ridge on the attachment side.
Apparently belonging to sect. Diplophragma, even though
herbaceous.
Apparently endemic to the mountains of Ponape (with a
variety on Truk), growing in the undergrowth in montane
rainforest and on exposed mossy peaks and crests.

Hedyotis pumila L. f.
Heciyoiis pumila L. f.. Suppl., 1 19, 1781. — Fosberg, Allertonia, 6:235, 1991.
Pro.strate herb, fonning small mats a few cm across, stems
square, minutely puberulent, especially near nodes; leaves
ovate, subsessile, 5-6 x 3.5 mm, acute, very slightly cuspidate,
margins and midrib scabrous, blade very sparsely so or
subglabrous, veins obscure, even the midrib, which is visible
because slightly carinate beneath; stipules with 2 prominent
subulate-setiform teeth, with or without several lateral much
reduced ones; peduncles and pedicels axillary, 1.5-4 mm long,
1 at a node except 2 to 4 sometimes terminally, or rarely 2 in
same axil, occasionally a peduncle with 2 pedicellate flowers,
but more usually a single pedicellate flower; hypanthium
campanulate-turbinate somewhat compressed, calyx lobes 1.5
mm long, ovate to triangular acuminate, margins scabrous
midrib slightly so; corolla tube cylindric, 1-1.2 mm long,
greenish white, lobes ovate, 1 mm long, spreading, pink or pale
lavender with 2 purple spots at base, throat with a few hairs;
anthers scarcely exserted, white, ovate; stigmas 2, white,
fleshy, oblong, slightly more exserted than anthers; capsule
broadly ellipsoidal, about 2 x 1.3 mm, with 4 strong costae and
4 weak or incomplete ones, disk in fruit elevated, compressed
transversally to septum, dehiscing loculicidally across disk,
fruit walls fiim-chartaceous; seeds brownish black, rounded on
outer side, sub-angular inward, about 0.3 mm greatest diameter,
surface shallowly foveolate reticulate, scar minute, not at all
sunken in a pit.
This tiny prostrate herb, collected on the University of Guam
campus, growing on bare or somewhat grassy soil, seems to be
new to Guam as well as to Micronesia and probably to the
Pacific Islands. It is said to be native to south and southeast
Asia, and seems to be rather weedy in its occurrence. It must
have arrived in Guam rather recently. The Guam plants differ
from the descriptions of the Asiatic ones in having pink or
lavender rather than white flowers.

Hedyotis sachetiana Fosberg
Hedyotis sachetiana Fosberg, Allertonia, 6:235, 1991.
Shrub with thickish subglabrous, somewhat fistulous main
stems, much more slender branches, branching at above 45°
angles, at least near summit, smallest branches tending to be
slightly hirtellous; leaves broadly elliptic, blades to 8.5 x 4.5
cm, abruptly sharply short acuminate, base acutely contracted
slightly decurrent, both surfaces appressed-hirsute especially
the lower, rather densely so when young, more sparsely when
older, main veins 4-6 on a side, network rather coarse, petiole
rather slender, hirsute, to 2 cm long; stipules about 5-8 mm
long, almost truncate except for pectinate margin with setiform
processes unequal, about 1 1 on a side, 1-3 mm long, entire
stipule and setiform processes strongly hirsute, becoming less
so in age, stipules connate into a funnelform cup, adnate to
petiole bases; inflorescences appearing verticillate but clearly
condensed branched cymes forming glomerules about 1 cm
wide, these axillary, from almost sessile to strongly peduncu-
late, peduncles to 2 cm long, or proliferating to a second
peduncle, the whole prominently hirsute, flowers almost sessile
to very shortly pedicellate; hypanthium hirsute, calyx-lobes
broadly linear, to 2.5 mm long, 0.5 mm wide, prominently
hirsute, tending to become recurved, persisting on fruit until
after dehiscence; capsule obovoid-subglobose,about 2.5 mm
long, hirsute, dehiscing completely septicidally, then about
half-way loculicidally; seeds conspicuously peltate, circular,
cellular-margined, reticulate, dark brown, base widely cuneate-
compressed, prominent.
This species is known only from the fairly complete type
specimen (which, unfortunately, lacks corollas). It seems
clearly related to H. tomentosa, with which it grows, but differs
in being much less densely, but more coarsely hirsute, not at all
white sericeous, in its broader, thinner, much less venulose,
much longer-petiolate leaves, in its strongly united almost
truncate (in general outline), rather than triangular scarcely
united, stipules, these not white sericeous, in its looser
glomerules, and in being a much larger plant, more leafy
distally. It could have been described as a variety of H.
tomentosa, but does not look like that species, which is quite
coherent and not particularly variable.
It is named for Dr. Marie-Helene Sachet, our late colleague
in Pacific island botany.

SMITHSONIAN CONTRIBUTIONS TO BOTANY
shortly petiolate; stipules triangular, with a heavy intermarginal
flange, margin strongly pectinate with many stiff setiform
gland-tipped processes; upper branches, rarely the terminal
shoot, prolonged into racemiform panicles, the bracteate
branches of these panicles divergent ascending, ending in a
small glomerule, or branching, branches ending in such small
glomerules, main ramifications with cordate foliaceous bracts;
hypanthium puberulent, calyx lobes erect, triangular, becoming
involute, persistent; corolla white or pale lavender, about 6 mm
long, tubular funnelform, lobes ovate, 3 mm, inside margins
woolly; anthers 1.5 mm long, well-exserted from sinuses; style
elongate, exserted about 5 mm, stigma lobes divergent
recurved; capsule depressed globose, 1 .5 mm x 2 mm, crowned

peltate, somewhat pentagonal or rectangular, reticulate.
Close to H. laciniata but with inflorescence pattern more like
that of H. fruticulosa. Notable for its long-exserted style. Has
been confused in herbaria with both of these species. Two
varieties may be distinguished.

Branched glabrous herb, stems to 3 dm long, prostrate to
decumbent or ascending, in all parts tending to be subfleshy
and marked by tiny white linear rhaphid bundles (probably
giving rise to the epithet “strigulosa” and perhaps also to the
epithet “albido-punctata”), leaves spatulate to oblong, obovate
or elliptic, 1-3 (-4) cm long, apex obtuse but slightly
mucronate, sub-fleshy or sub-coriaceous, base gradually
narrowed to a broad attachment or a short slightly winged
petiole, veins except midrib obscure; stipules linear with an
abruptly broadened base that is adnate to the p>etiole-base,
frequently one (or even 2) pairs of subordinate lateral linear
teeth; flowers borne in open few-flowered (3 to 10), somewhat
irregular cymes, terminally and in upper axils, the plant in
extreme cases appearing paniculate, lowest bracts reduced
leaves, upper ones thick scale-like ovate to linear or subulate,
carinate, distal “pedicels” sometimes bracteolate, pedicels
usually thick, scarcely filiform; hypanthium fleshy, calyx-lobes
narrowly to broadly ovate, obtuse to acute or cuspidate, erect,
persistent, 1-1.5 mm long, united at base, scarcely enlarging in
fruit; corolla tube shorter than calyx, swollen, throat contracted,
lobes ovate to oblong ovate, somewhat exceeding calyx,
bearded at base in throat; capsules broadly obovoid, about 3 x
3.5 mm, loculididal, slightly compressed; seeds minute, about
0.3 mm high and wide, somewhat obpyramidal, top convex,
angles not sharp, surface dull blackish brown, papillate.
This species is related to H. biflora, being sometimes hard to
distinguish from it when dry, but when fresh notable for its firm
fleshy leaves and stiffish stems and cymes, and larger fruits.
Found on limestone shores and sea-cliffs throughout the
western Pacific.

SMITHSONIAN CONTRIBUTIONS TO BOTANY
subglobose to globose, to 2 mm long and wide, hirsutulous,
dehiscing completely septicidally, then slightly loculicidally;
seeds peltate, 0.6-0.8 mm across, rounded to quadrangular or
hexagonal, dull brownish black, attachment on a sharp
wedge-like ridge or projection, testa obscurely reticulate.
Related to H. fruticulosa, differing in leaf shape, more
slender and divaricately branched inflorescence, which is much
more strongly hirsutulous, calyx lobes linear, flowers and fruits
much more tightly capitulate. Perhaps even more closely
related to H. scabridifolia, as suggested by Hosokawa,
differing in narrower bracts, shorter petioles, narrower leaves,
more strongly hirsutulous inflorescence, tighter capitulae,
linear strongly recurved calyx lobes, included stamens, and less
reticulate seeds. These three, perhaps with H. laciniata, form a
closely related group, and are more remotely related to the H.
divaricata group.
Known only from Palau, and only definitely from the type
collection and one other. Possibly some of the plants from
Palau earlier referred to H. fruticulosa belong here.

Diffusely branched villous herb with square sulcate stems,
more prominently villous in the sulci; leaves thin, ovate to
ovate-lanceolate, strongly acuminate, about 5-9 x 2-2.5 cm, 4
or 5 nerves on a side, prominent beneath, impressed above,
blade sparsely appressed hirsute on both surfaces, spreading
hirsute on nerves beneath, petiole about 5 mm, densely pilose;
stipules low triangular, with 3, rarely more, long very slender
pilose setae; inflorescences pedunculate, several in an axil,
usually also on a dwarf axillary branchlet, peduncles rarely
unbranched, usually once or twice umbellately branched, each
ultimate branch ending in a small globose glomerule or head of
flowers, subtended by filiform bractlets; calyx lobes linear,
persisting on fruit; corolla tubular to slightly campanulate, tube
about 1 mm long, lobes subequal with it, oblong-ovate, pilose
externally, especially toward apex, glabrous within; stamens in
sinuses, anthers oval, slightly exserted; fruit a small globose
nut, rugose externally, with a hard bony indehiscent endocarp,
8 or 10 seeds irregularly angular, notably reticulate.
Related to Hedyotis awicularia, but differing notably in the
pedunculate inflorescences several in an axil, the peduncles
branched. Several varieties are apparent, based on pubescence
and leaf-shape; var. vestita not known from Micronesia, but
one variety described (as a species) from Palau.

Stems articulate-nodose, 4-sided when very young; leaves to
7x2 cm, oblong, rounded at both ends, very shortly petioled,
chartaceous, lateral veins 4 or 5 on a side, visible on both sides,
inflorescence tuberculiform, very small; flowers crowded,
sessile, clavate in bud, calyx truncate, ciliolate; corolla tubular,
about 7 mm long, throat glabrous, lobes ovate, slightly
cucullate, anthers broadly elliptic, subsessile, fertile in bre-
vistylous flowers, smaller in longystylous flowers, possibly
sterile; disk elongate exceeding calyx, style filiform, stigma
slightly 4-lobed; fruit about 7 mm long, obovoid; pyrenes
obovate, plano-convex.
Distribution Fiji to Palau. Apparently very rare in Palau,
found only by Kraemer in 1910. We have not seen the
specimen, probably destroyed in Berlin in World War II.
Smith and Darwin (1988:244) reduced this species to
Hydrophytrum longiflorum A. Gray, which they regard as a
Fijian endemic, though mentioning with doubt the Caroline
Island report. Because we have seen no Palau specimen and
because the Kraemer collection on which Valeton based the
report was probably destroyed, we hesitate to follow the
inclusion of H. horneanum in H. longiflorum, and to report the
latter from Micronesia. We are, therefore with strong reserva-
tions simply including the plant, as originally reported by
Valeton. We have little doubt that a tuberous myrmicophilous
Rubiaceae was found by Kraemer, and hope that, by including
and discussing it, we may interest collectors in searching for it.
If found again, it would be one of the most interesting of
Palauan plants.
Ixora L.
Ixora L., Sp. PI., 1 10, 1753; Gen. Pi., ed. 5, 48, 1754 [= 1753]
Shrubs and small trees; leaves simple, entire, sessile or,
usually, shortly petiolate; stipules usually ovate-triangular and
aristate-mucronate, or ovate-lanceolate, stiff, tardily caducous
or persistent; inflorescence thyrsoid, decussately branched, or
trichotomous, sometimes congested or much reduced, terminal
or rarely pseudo-axillary (on reduced branchlets); calyx
cup-shaped often very short, 4-dentate or lobed; corolla
salverform, tube slender, lobes 4 (rarely 5), contorted; stamens
attached at or below sinuses, exserted and reflexed, anthers
pointing downward outside the sinuses; style elongating tardily
and becoming well exserted, bifid, branches flattened, stig-
matic within, becoming recurved after style elongates; ovary
2-(very rarely 4) loculed, one ovule in each locule, attached to
septum; fruit a drupe with 2, rarely 4, stones, endocarp indurate,
thin, plano-convex, with a narrow ventral groove, seed
plano-convex.
A large pan-tropical genus, often with showy flowers. A
number of species widely cultivated as ornamentals; two
species native, at least three cultivated in Micronesia, including
one the natives. Of the five valid species previously recorded
for Micronesia one, 7. amplexifolia, can defmately be excluded
from the flora as a misidentification; another I. chinensis, is
considered doubtfully present in cultivation, as no specimens of
this species from the area have been seen by us. A number of
species and varieties, described from Micronesia, are here
regarded as belonging to 7. easel Hance. Valeton ’s record of
Ixora amplexifolia Lauterbach & Schumann seems to be based
on a very fragmentary specimen of Eugenia stelechantha
(Diels) Kanehira. Hosokawa (1937:202) was the first to suggest
this. The Kramer specimen on which this record of a New
Guinea species was based was very fragmentary, only a pair of
leaves and an incomplete fruit, which, from Valeton ’s
description, could better be a Eugenia. It was probably
destroyed in the Berlin herbarium. We have no hesitation in
excluding 7 amplexicaulis from the Micronesian flora.

Shrub, becoming almost tree-like and up to 6 m tall,
glabrous, sparsely branched; leaves oblong to elliptic or
broadly lanceolate, up to 30 x 12 cm, usually smaller, often
much smaller, firm chartaceous, 12 to 18 veins on a side,
arching slightly forward, usually weaker veins alternating with
them, anastomosing toward margin, apex somewhat acuminate,
base acute to attenuate, petiole 0.5-2 cm; stipules sheathing.
free portion broadly ovate, acuminate or mucronate; cymes red,
ample, terminal, quite varied in size, from flattish or
hemispheric to almost globose-thyrsoid, main axis with 4 to 6
intemodes, trichotomously branched at each node, branches
3-5 times trichotomous, a pair of scale-like tracts connected by
stipules at each ramification; flowers very many, brilliant
scarlet to orange red, calyx short, margin undulate to broadly
and very obtusely 4-toothed; corolla tube slender, 2. 5-3. 5 cm
long or often shorter, lobes 4, ovate, about 1 cm long, slightly
acuminate or acute, sometimes considerably smaller; anthers
linear, exserted from sinuses on fairly long filaments, style later
strongly exserted, stigma bifid, the lobes becoming recurved;
fruit subglobose 6-7 mm long, red turning dark, few setting in
an inflorescence.
The leaves of this species vary remarkably in size, and
somewhat in shape. The size of the thyrses varies also,
sometimes reaching 15 or even 20 cm wide.
The plant is native on at least all the high Carolines and
introduced into cultivation in Australia long ago from Kusaie,
distributed from Sydney or Melbourne and now cultivated
under various names throughout the tropics. Frequently
confused with Ixora coccinea. It is introduced at least into the
Marianas and northern Marshalls in Micronesia.
Uses.— Spear shafts were made of the stems, also punting
poles and rafters. Medicinally for stomach ache: Leaves of
“gachuw” are mixed with crumbs of copra, and taken with
coconut milk; for nausea: Decoction of young leaves of
“gachuw” is taken (Yap: Okabe, 1943). Wood. . .the men like to
use it when they make copra husking stakes. Also used for
braces for canoe outriggers. The small branches are often made
into fish hooks (Sonsorol: Berry 10). Buds are used in medicine
for illness caused by spirit of breadfruit. Used in garlands. Used
as “ways” when beaching canoe (Woleai: Alkire 29). Roots are
used as a hemostatic in menstruation. In former times spears
were made from the wood (Ponape: Classman, 1952). Branches
used for rim of flying fish nets, flowers in leis occasionally,
sticks used by children in a game called “apis”; sometimes used
as a Christmas tree (Namoluk: Marshall 69). Flowers used for
garlands, put around head when dancing, wood for scoop net

This species is probably not in cultivation in Micronesia, but
if a plant with orange, salmon, yellow or white flowers with
corolla lobes round at apex and not more than 6-7 mm long
should be found there, it might probably be this species. Plants
that have been referred here are Ixora coccinea color forms
with unusually wide, obtuse corolla lobes.

Ixora chinensis sensu Stone, pro parte, Micronesica, 6:550, 1971 [non
Lamarck, Encycl., 3:344, 1789],
Large shrub or small tree, glabrous; leaves narrowly elliptic
to oblong, or slightly obovate, apex obtuse or slightly bluntly
acuminate, base narrowed to a short petiole; stipules shortly
sheathing, lobes slightly developed, with a double carina that
runs into a short strong mucro that sometimes appears double,
rarely suggestive of additional double carina and subsidiary
teeth or mucros; inflorescence a dense terminal trichotomous
thyrsoid cyme with a short peduncle subtended by a pair of
reduced leaves or foliaceous bracts or these immediately
subtending the 3 branches of the cyme, main rhachis of 2 or 3
(-4) short intemodes, ramifications subtended by narrowly
linear bracts, one on each side; calyx lobes large, to 5 x 1.5 mm,
somewhat united at base, pale greenish white with 3-5 parallel
green nerves, erect; corolla white, tube slender, less than 1 mm
thick, 2.5-3. 5 cm long, lobes about 5x3 mm, tending to be
revolute, apices rounded; anthers linear, about 3.5 mm long,
tapering to a point; style well exserted, stigma deeply bifid,
lobes strongly recurved; fruit not seen. Cultivated plant
probably a self-sterile clone.
Native of Indo-China Peninsula, widely cultivated pantropi-
cally. Not common in Micronesia.

Ixora incarnaia (Blume) de Candolle, Prodr., 4:486, 1830 [non Roxburgh ex

Shrub, glabrous except inflorescence, youngest branchlets
somewhat compressed, at least when dry; leaves elliptic, to 10
X 4 cm at least, apex acutish, base rounded, veins 6-8 on a side,
not prominent, petiole thickish, about 5 mm long; stipules
triangular, slightly united at base, carinate, gradually or
abruptly acuminate into a long subulate apex; inflorescence a
terminal condensed thyrsoid cyme, peduncle short, bearing a
pair of small ovate foliaceous bracts half-way up, these
sometimes with much reduced cymes in their axils, cymes
spreading puberulent, trichotomous, main axis of 2-3 short
intemodes, a tapering subulate bract on each side of main
ramifications, this with or without 1 or 2 teeth at base; flowers
crowded, sessile, bracteolate, pink or old-rose; hypanthium and
calyx puberulent, calyx lobes triangular to slightly acuminate
almost as long as hypanthium, erect; corolla tube slender, about
2 cm long, lobes ovate, 5-6 mm long, acutish, throat glabrous;
anthers lanceolate with sagittate bases, about 3.5 mm long;
style exserted about 2.5 mm, stigma about 1.5 mm long, the
narrowly lanceolate lobes tardily spreading; fruit not seen.
A cultivated pink-flowered shrub, native of south Asia seen
only in and around Agana, Guam. At first thought to be /.
chinensis or I. fmlaysoniana but differing in many small
details, especially from /. chinensis in the acute corolla lobes,
and from I. fmlaysoniana in the much smaller calyx.
We have no authentic material, or even any specimens
purporting to be I. siamensis or /. incarnata (Blume) de
Candolle, but from available descriptions and the fact that
Bremekamp (1937:211) considered it a commonly cultivated
species, we feel that this is probably the correct disposition. The
name I. siamensis is not widely known horticulturally, but is
the correct name, because I. incarnata is unavailable.

Mitracarpus Zuccarini
Miiracarpus Zuccarini in Schultes, Mantissa, 3:210, in obs. 1827.
Mitracarpum auct. [sphalm.].
Mostly slender herbs with squarish or 4-ribbed stems; leaves
simple, linear to ovate, sessile or short-petioled, somewhat
sheathing interpetiolar stipules with several to many stiff awns
or setae pectinate on margins; dense heads or verticels of small
flowers, calyx with unequal white-margined lobes; corolla
salverform, 4-lobed; fruit a thin-walled circumscessile capsule;
seeds 2, with a cross-shaped ventral groove.
A principally tropical American genus of quite a few
ill-distinguished species, one of which is weedy and has
become pantropical; common on Guam, recently found in
Palau.

[non Schumann in Engler and Prantl, Nat. Pfianzenf., 4:144, 1891].
Erect herb, to 40 cm tall, stems nearly square, hirsute; leaves
lanceolate to ovate to somewhat obovate, obtuse to acute at
apex, sessile to slightly petiolate, rounded at base, scabrous to
hirtellous, especially on nerves beneath, nerves 2 or 3 pairs,
strongly ascending; stipules very low-sheathing, hirsute,
margins pectinate with hirtellous awn-like processes; flowers
in crowded head-like verticels in axils of pairs of leaves and
terminal, hirsute, calyx lobes unequal, 4, 1 pair much longer
than the alternate one, ovate-acuminate, hirsute, other pair
much smaller, varied in size, ending in a hair-like tip; corolla
salverform, white, scarcely equalling or exceeded by the calyx,
lobes 4, ovate, blunt; anthers elliptic or oval, slightly exserted;
capsule obovoid, circumscissile, cap crowned by erect persis-
tent calyx lobes; seeds broadly oblong, rather flattish, dull
yellowish, with a “hammered” appearing surface, an x-shaped
ventral groove.
A very common weed, especially on volcanic soil, probably
annual, of tropical American origin, long present in Guam,
found in 1818 by Chamisso, who thought it native, and
described it as M. torresianus. It is easily mistaken for a

Caelospermum Blume, Bijdragen, 994, 1827.
Trees, shmbs and lianes with rhaphid bundles; leaves entire,
pinnately veined; stipules entire, tardily caducous; flowers
capitate, heads pedunculate, terminal, axillary or leaf-opposed;
hypanthia connate, flowers 4-7 merus, calyx united at base and
to various lengths, one lobe enlarged and showy in some
species, not constantly so; corolla hypocraterform, lobes
valvate; style 1, bifid; ovaries and fmits connate, ovary cells

Morinda indica L. ex Merrill, Phil. Journ. Sci. Bot., 9:149, 1914 [nomen
nudum, probably an inadvertance, as the reference given is that for Morinda
ci trifolia L.[.
Glabrous tree to 5-7 m tall, with dense crown; dull reddish
brown squarish twigs, “terminalioid” or “double terminalioid”
branching from 2nd to 4th node back from tip, first intemode of
twig 10 or more cm long, second 1-2 cm, peduncle
leaf-opposed at tenninal node, but branch then continues;
leaves elliptic to ovate or oval, up to 25 cm long, 20 cm wide,
usually narrower, apex obtuse, sharply mucronate, base cuneate
to a thick petiole 1-2 cm long, 6 to 8 main veins on a side,
alternate to opposite, anastomosing near margin, nerves
connected by ladder-like, but not quite straight cross-veins,
finer network obsure; stipules prominent, leaf-like in texture,
obtuse to rounded, somewhat narrowed to base, barely
sheathing or not, caducous below 3 to 6 nodes; peduncle
strongly recurved, about 1-1.5 cm long, borne on 1 to 3
terminal nodes of small lateral branches, many ovaries fused
into a syncarp, flowering from base toward apex, buds of all
sizes present apically; calyx reduced to an almost imperceptible
collar; corolla in bud clavate, valvate, rounded apically, white,
tube 12-13 mm long, pilose within, scarcely dilated apically,
lobes 5, ovate-oblong, about 7 mm x 3 mm, acutish to obtusish
with a slight incurved appendage, lobes recurved; anthers 5,
attached just below sinuses dorsally at about middle, on short
filaments; style bifid into 2 thickened recurved stigmas that are
exserted about 2 mm; fruit an irregularly formed white fleshy
syncarp up to 10x5 cm usually narrower, varying to globose
when small (most Gardner specimens seen no more than 4.5 x
6 cm), with prominent spirally arranged disks 5-6 mm across,
each in a polygon faintly marked on surface, beneath each of
these 4-5 tangentially arranged, cuneate, compressed pyrenes.
Uses. — Wood used as building material, root for tan dye;
fruit and root used medicinally as an ingredient in backache
remedy (Rota: Fosberg 24952). Bark of root used in dyeing
Guam: Guadichaud, 1826). Root used for dyeing magenta
(Guam: Safford & Seale 1082). Wood used for constmction of
huts (Guam: Safford & Seale 1006). Leaves applied to forehead
to cure headache (Guam: Fosberg 25402). Fruit eaten in times
of famine (Hall I., Nomwin: Fosberg 24578). Root used for
blue dye, leaves used medicinally (Jaluit: Fosberg 26687).
Leaves and fruit used medicinally (Likiep: Fosberg 27056).
Fruit eaten when ripe and soft (Truk, Udot: Fosberg 24497).
Fruit eaten when other food short; dye obtained from root
(Nauru: Burges ms., ca. 1935). Root used in making red dye;
terminal leaves in treatment of sprains; fruit eaten but not
well-liked (Yap: Wong 324). The fruit is reported edible but is
hardly attractive (Northern Marshall I.: Taylor, 1950). A tree,
the wood of which is used for the framework of a house. The
leaf, root, and fruit are strongly medicinal. The seeds are
pulverized and the pulp applied to any tooth that is causing
pain. The root is scraped, then the scrapings, together with
young coconut husk, are boiled to make a light brown dye for
handicraft fibers, such as Triumfetta, Hibiscus, and young
coconut leaf, but not for Pandanus (Bikini: St. John and
Mason, 1953). The leaves of this sf>ecies are used in
conjunction with other plants as a cure for rheumatism; the
stipules are employed in the treatment of wounds caused by
scorpion fish; the terminal buds, on abscesses; the inner bark
and root, as a hemostatic in menstruation; the young flowers, to
relieve pain after childbirth; and young fruit, to alleviate pain in
heart attacks. (Ponape: Glassman, 1952). Fruit eaten as a male
contraceptive (Mortlock I., local informant in Guam).
Two varieties are distinguished, one widespread, one
sporadic, commoner further west.

Morinda citrifolia var. bracteata (Roxburgh) Hooker f.
Morinda citrifolia var. bracteata (Roxburgh) Hooker f., R. Br. Ind., 3:156,
1880. — Fosberg, Sachet, and Oliver, Micronesica, 15:271, 1979.
Morinda bracteata Roxburgh, Hort. Beng., 15, 1814.
Differs from var. citrifolia in having one calyx lobe of some
of the flowers in a syncarp enlarged and conspicuous, white,
obovate, to as much as 1 cm long.
This form is common farther west, as in India, rare in
Micronesia. This character, of an enlarged calyx lobe, is found
widely in the Rubiaceae, frequent or constant in some genera,
rare in others, seldom found in all flowers in an inflorescence.
Infrequent in Morinda citrifolia, seemingly constant in some of
the other species, e.g., M. latibracteata. The enlarged calyx
lobes are sometimes incorrectly referred to as “bracts.”
Medical Uses. — The following information was recorded
on Sonsorol Island, by Paul Berry, 5 Apr 1968. It is not clear
from Berry’s account whether or not he distinguished the two
varieties of Morinda citrifolia, but it seems likely that both
were present and that the name “rom” applies to both, though
his specimen, no. 32 is var. bracteata. The following are the
botanical identities of the other plants mentioned as compo-
nents of the remedies he describes that involve Morinda
citrifolia L.
fitoa (Berry 25) = Calophyllum inophyllum L.
glamahi (Berry 112) = Scaevola taccado (Gaertner) Roxburgh
glawira (Berry 69) = Allophylus timoriensis (de Candolle)
Blume
gleiwaru (Berry 103) = Pangium edule Reinwardt
halifato (Berry 45) = Eugenia javanica Lamarck ?
malat (Berry 78) = Soulamea amara Lamarck(?)
rifouth (Berry 74) = Mammea odorata (Raflnesque) Koster-
mann
The inner skin of the trunk can be scraped, pounded and put
in an uru, and the juices can then be squeezed on a cut. For 3 or
4 days only the juices will be used, after the fourth day when a
scab has formed, the shavings may be applied directly to the
cut.
When someone has a pain in the side and cannot breathe
NUMBER 81

well, three young leaves can be mixed with the small nuts and
the shavings from the inner skin of the roots; these are pounded
and put in an uru and squeezed into a young coconut and drunk
3 times a day, for 3 days only. This medicine will help relieve
the pain.
Eye medicine: Four young leaves of roru can be mixed
with five young leaves of glawira (69) these are then pounded
and squeezed into the injured eye.
Only two drops of this for very serious injury, one drop for
less serious. Water cannot be put in the eye before or after the
medicine is used or the medicine will be of no value.
Another recommended use: Six drops the first day, 3 or 4
drops the next day, applying 2 drops to the eye not injured. No
water can be put in the eye before or after use of the medicine;
the medicine can spoil and even blind the patient. If there is no
bleeding in or around the eye then the medicine is used only
two days; however, if there is bleeding then the medicine is
used longer.
For swelling to the body: By facing the tree and scraping a
surface root on the right side, the scrapings can be used as
medicine, they are wrapped in the leaves, heated and applied to
the swollen area.
Stomach pain: The young leaves can be pounded, then
squeezed into a container and drunk for relief of stomach pain.
When someone is suffering from a backache, the leaves can
be spread on the sleeping mat to help relieve the pain. For joint
pain, the leaves may be tied directly to the ailing joint.
The people speak of a hard lump that may appear on parts of
the body, such as the wrist, so to get rid of this they use the
following medicine.
The leaves of malat (78), the young leaves of roru, the young
leaves of gleiwaru (103), the young leave of glamahi (112), the
young leaves of Fitou (25), are mixed, pounded and squeezed
on the hard lump. The area will then open like a cut and drain.
While it is healing, the opening will be washed in salt water,
then rifouth (74), and halifato (45) leaves are pounded and
squeezed on the cut, to complete the medicine and close the
opening.

Tall shrub or small tree, glabrous except for small tufts of
hairs in domatia in axils of leaf veins; leaves broadly, rarely
narrowly, elliptic to somewhat obovate, 8-15 x 3-5 mm,
apices shortly acuminate, bases contracted, slightly decurrent,
blades with 7 sub-opposite pairs of secondary veins, arching,
forming an undulate submarginal vein; stipules short-
triangular, blunt to mucronate, slightly connate at base; heads
on axillary peduncles in upper axils, peduncles about 2.5-3. 5
cm long, heads about 5 mm across, excluding “bracts,” flowers
4-12, lower parts of hypanthia connate, calyces subtruncate
with one enlarged lobe of which the base is broad, comprising
one third or more of the calyx rim, oblanceolate to spatulate or
broadly obovate, apex acute to bifid or irregularly shallowly
lobed or toothed or subtruncate, base cuneately contracted,
about 8 strong veins from base spreading and somewhat
anastomosing distally, color white, deciduous from fruit; fruit
globose, irregular, about 1 cm across, fleshy.
The “bracts” are really enlarged calyx lobes, as are found in
many Rubiaceae.
A very distinct species, apparently endemic to the Palau
Islands.

Contr. U.S. Nat. Herb., 9:330, 1905.
Shrubs, small trees or lianas; leaves opposite, thin; stipules
tardily caducous; inflorescence a terminal cymose panicle with
caducous scale-like bracts; calyx lobes separate nearly to base,
in central flower of some cymules the outer calyx lobe much
enlarged and showy, stipitate, calyx caducous from even young
fruit; corolla salverform, tube and throat about equal, buds
plicate; fruit fleshy, often with conspicuous white lenticels,
locules 2, placentae fleshy, axile, shield shaped, longitudinally
attached, the two sides recurved, all surfaces covered by
numerous small seeds.
An Old World tropical genus with few highly variable or
many ill-defmed species.
Mussaenda frondosa L. has been reported a number of times
from Micronesia, beginning with Safford (1905:330), who,
without specifically saying so, presumably found it on Guam.
Subsequent reports are all from the Western Carolines. A.C.
Smith (1945) and Jayaweera (1964) referred the Caroline
Islands plants to Mussaenda philippica, which seems a
satisfactory disposition for them, for the present. The entire
complex related to M. frondosa deems too closely related, and
with further study may turn out to comprise a series of varieties
of that species.
The Guam reports remain doubtful, as Mussaenda has not
been found on Guam by any modem collector, to our
knowledge, and no Safford specimen is known. In the absence
of a specimen we feel justified in excluding M . frondosa from
the Guam flora, and from the flora of Micronesia. Mussaenda
frondosa is regarded by both Smith and Jayaweera as confined
to Ceylon and India.

Large shrub or small tree, glabrous to minutely appressed
puberulent; leaves ovate-elliptic to elliptic, to 17 x 6 cm,
strongly acuminate, base contracted to a slender petiole 1-1.5
cm long, veins 9 to 12 on a side; stipules sericeous, triangular,
with a deeply bifid acumen; panicle about 4 times trichoto-
mous, densely sericeous to soft-pubescent, bracts linear,
bracteoles irregularly and inequally trifid, segments linear to
filiform, flowers apparently dioecious; calyx caducous even
from rather young fruits, lobed almost to base, principal lobes
5, outer one greatly enlarged and showy on a few flowers,
unmodified lobes somewhat unequal, linear to narrowly
lanceolate, tips subulate, much variation even on a single plant,
usually somewhat striate or carinate on back (especially on Yap
plants), calyx usually somewhat less sericeous than cyme and
hypanthium, small extra subulate lobes accompanying the
enlarged leaf-like lobe, which is up to 9 cm long, broadly ovate,
acuminate, somewhat cordate or rounded or obtuse at base,
stipitate (“petiolate”), white, membranous, thinly sericeous,
veins prominent; corolla 2-3 cm long, densely but shortly
pubescent without, limb ovoid in bud, acuminate, tips of lobes
separate, lobes ovate acuminate, bright yellow and densely
puberulent within, center of staminate flowers shortly bearded
and throat densely yellow hirsute within, 7 mm long, tube
glabrous within, 2 cm long, anthers 4-5 mm long, linear or
subulate; pistillodes about 5-7 mm long, glabrous, with 2
connivent lobes about 2 mm long; pistillate corollas with tube
and throat subequal, about 1 cm long, throat somewhat yellow
puberulent within, no beard, tube glabrous within, antherodes
subulate, 4 mm long; pistil with glabrous filiform style and
subexserted stigma about 7 mm long, linear, bifid almost to
base into slender blunt lobes papillate on inner surfaces and
margins; fruit (not quite mature) broadly ellipsoid, 2 cm long,
13 mm wide at middle, thickly beset with white lenticels.
Careful study of living specimens, during preparation of the
above description, suggest that this species is really dioecious,
rather than merely heterostylous, as considered by Jayaweera.
The pistil in the staminate plant {Fosberg 47416) is reduced to
a pistillode 5-7 mm long, with lobes connivent, about 2 mm
long. The antherodes in the pistillate plant {Fosberg 47417) are
subulate, about 4 mm long.
These plants from the western Carolines are probably best
referred here, though they are hard to distinguish from those
from the South Pacific and westward in Malesia and even India
and Ceylon. They have commonly been referred to M.
frondosa, the original Ceyleonese species of the genus.
Discussions by A.C. Smith (1945) and Jayaweera (1964)
indicate that the Caroline Island plants are not separable from
the widely spread M. philippica of the Philippines and Solomon
Islands, which is a logical phytogeographic relationship.
This species, interpreted broadly, extends from the Philip-
pines to the Caroline and even the Solomon Islands. In
Micronesia it is known from Palau, Yap, and Fais. On Palau the
pubescence ranges from close and thinly sericeous to loosely
appressed and almost shaggy. On Yap only the sericeous forms
are represented (so far as BISH and US specimens go). The
Palauan plants are said to tend to erect bushiness while Yap
ones tend to be rather sprawling.

This differs from Mussaenda philippica var. philippica, as
described above, in having some or all of the calyx lobes
enlarged and white.
This highly ornamental shrub was found in the forest in the
Philippines by Hugo Curran, and propagated by cuttings, and is
now widely planted in the tropics, including Guam. We treat it
here as a botanical variety rather than as a cultivar because it
did not originate in cultivation. Mr. Souder informs us (pers.
comm., 1967) that two hybrid cultivars have been planted in
Guam, c.v. Luz and c.v. Dona Trining. They are hybrids
involving var. aurorae.
Seen cultivated in Guam and Palau-Koror.

Vernacular Names. —
meldii (Palau: Fosberg et al., 1980; Fosherg 47564)
metsibech (Palau, Koror: Valeton, 1930; Raymundus 142)
odoid (Palau: Fosberg et al., 1980)
tielar bekai (Palau: Fosberg et al., 1980)
This species, endemic to Palau, is widely distributed on both
volcanic and limestone substrata. Plants from limestone areas
differ slightly from those on volcanic soils. Their leaves tend to
be broader and frequently somewhat obovate or broadly
oblanceolate, and the plants to be slightly more slender. The
cymes are usually somewhat more slender, and the corolla tube
are usually more slender and sometimes shorter. The type from
Koror, Raymundus 124, which was probably lost in the Berlin
bombing, was described as having the leaves narrowly elliptic
to lanceolate, suggesting that it may have come from the
volcanic part of Koror. Mature fruiting specimens from the
volcanic areas are lacking. Darwin, in his revision of the Pacific
species (1976) rejects var. hiseta as the stipule character does
not hold up, and mentions the narrower leaf width. He cites
material of this species from both volcanic and limestone
substrata, but does not suggest any taxonomic separation.
Further consideration of this possibaly should await collection
of more ample flowering specimens from the limeastone and
mature fruiting ones from the volcanic ones. Darwin, 1976:48,
regards O. palauensis as related to eastern Asiatic species,
rather than to other Pacific species.

choose to point out the respects in which this specimen,
Cheatham 39, cited below, differs. If eventual comparison with
the type shows that the two are really incompatible this
specimen can be made the type of a new species.
Leaves elliptic, to 8 x 4 cm, prominently acuminate, thinly
but stiffly coriaceous, inflorescence hemispheric, 5-6 cm wide,
on a peduncle 4 cm long, minutely bracteate, fruits somewhat
crowded but not glomerate, seeds with a roughened black
surface and a very hard deeply ruminate rather than entire
endosperm. The leaves resemble closely those of P. sarmentosa
Blume.
Type: Palau, Babeldaob, Aimirik, Kanehira 2340 (FU?) not
seen by us. Known until now only from the type specimen. We
have not seen the type of this climbing species, but presume it
is allied to the south Asian and Indonesian P. sarmentosa
Blume, differing especially in leaf shape and texture. Addi-
tional specimen from Babeldaob, “road from Airai to Nekken,”
Cheatham 39 (US).

Shrubs to several m tall, branched, slender, glabrous to thinly
woolly-pilose; leaves thin, up to 10 x 3-4 cm, mostly smaller,
elliptic to ovate or somewhat obovate, obtuse to somewhat
acuminate, base acute to obtuse, veins clearly visible beneath
but not prominent; stipules narrow, to 1 cm long, usually much
smaller, strongly bifid and only united a short distance to
half-way above base, early caducous, glabrous to pilose, in one
variety divided distally into many slender threads; inflores-
cences axillary, varying from a solitary flower to fascicles or
almost sessile glomerules, to pedunculate and glomerate, to
variously cymosely branched, always slender, often capillary,
with small scale-like caducous bracts at ramifications, flowers
from pedicellate to subsessile and then in few-flowered
glomerules, calyx patelliform to cup-shaped, margin almost
entire to denticulate or somewhat deltoid-lobed, persistent on
fruit; corolla salverform to funnelform with 4 or 5 lobes, tube in
some forms somewhat ampliate above, or sub-campanulate,
throat at least usually strongly bearded; drupes red, when dry
usually somewhat longitudinally plicate, ovoid to ellipsoid,
pyrenes flat on inner face, more or less tricarinate dorsally, also
frequently somewhat rugose; seed with endosperm entire.
This species is found in a large number of varieties, on most
high islands in Micronesia. It is perplexingly variable, and has
been split into many species. These seem to intergrade so
thoroughly that they merit at most no more than varietal rank.
The stipules and the branching of the inflorescences, as well as
the pubescence, provide the principal differences.

Psychotria hombroniana var. canfieldiae Fosberg
Psychotria hombroniana var. canfieldiae Fosberg, Allertonia, 6:253, 1991.
Shrub or small slender tree, branchlets glabrous, brown to
blackish; leaves broadly lanceolate to narrowly elliptic, 5-8,
rarely 10 cm long, strongly acuminate, rarely acute or even
obtusish, base gradually contracted, blade thin, glabrous or,
when very young, pilose on under side along midrib, usually
soon glabrate, petiole slender, to about 1 cm; stipules
sheathing, strongly bifid into very slender points these more or
less filamentose, especially distally (filaments often rubbed off;
cymes filiform to capillary, 1-4 cm long, sparsely branched
once or twice, glabrous to sparsely pilosulous, flowers
subsessile, 2 or 3 at ends of branches.
The stipules of this variety are distinctive, in general
resembling those of var. squarrosa, but clothed, distally by
long filament-like hairs; this character seems quite constant,
except that the hairs tend to be rubbed off on specimens subject
to handling.
Known only from the karstic limestone islands of the Palau
Group, where common in undergrowth on steep slopes and
ridges.

Psychotria ponapensis Fosberg, Occ. Pap. Bish. Mus., 15:224, 1940. —
Classman, Bish. Mus. Bull., 209:96, 1952.
Shrub, generally more or less pilose, at least young growth,
leaves ovate to elliptic, acute to acuminate, hairy beneath at
least along mid-rib, often glabrate when mature; stipules more
or less pilose to woolly-pilose, bifid, with 2 ridges in lower
part, united, at least lowest part; cymes filiform to capillary,
pedunculate, once or twice branched, shorter than to subequal
with leaves, at least somewhat pilose, quite variable in density
of pubescence and development of cymes, also in size of
leaves.
Known from Palau, Truk, Ponape, and Kusaie, including the
generally, though often sparsely, pubescent plants with bifid
hairy stipules. Amaracarpus macrophyllus and A. kraemeri
Valeton (p. p.) probably belong here, judging by their
descriptions, but their types are missing and we cannot be
certain.
Regarded by Fosberg, 1940, as a distinct species, but it
seems to us now only a pilose variety of P. homhroniana sensu
lato. Specimens from Kusaie have narrower leaves than most of
those from Ponape and the two available from Truk.

Shrub to 4 m tall; leaves broadly lanceolate to narrowly
elliptic or narrowly obovate, to 10x3 cm, apex acuminate, base
acute to cuneate or slightly decurrent, glabrous except sparsely
long-pilose along midrib beneath, hairs strongly appressed to
blade, veins 5 to 8 pairs, anastomosing near margin, spreading
at right angles from midrib; stipules glabrous, united at base
and to middle in some specimens, bifid into two strong
acuminate points, dorsally with two ridges or keels part way in

glomerules, some usually in glomerules on short (to 1-1.5 cm)
peduncles, these filiform to capillary; corolla white and
strongly bearded in throat (except in Stone 5134 said by
collector to be yellowish green and throat glabrous); fruit
ellipsoid, pyrenes weakly or scarcely carinate.
The variation in shape, color, and pubescence of corolla
suggest need for further field study. Known only from the

Psychotria hosokawae Fosberg
Psychotria hosokawae Fosberg, Allertonia, 6:257, 1991.
Woody plant, glabrous, terete or slightly squarish when very
young, 1-3 cm long, nodes not significantly enlarged; leaf
blades oblanceolate, to 19 x 5 cm, sharply acuminate, base
cuneate, main veins 12 to 14 on a side, visible but scarcely
prominent, arching upward, anastomosing very close to
margins, petiole slender 2-3.5 cm long; stipules caducous, a
dense row of multicellular hairs in their axils, stipules not
available except for an obscure and much reduced pair on a tiny
branchlet at the terminal node, apparently calyptrate, 8 mm
long, with two flat appendages at apex; inflorescence a cluster
of 5 once- or twice-branched small cymes about 2 cm long at
terminal node, in bud only, pedicels strongly ascending; calyx
spreading, rotate, scarcely lobed but margin strongly crispate-
undulate; corolla buds about 1 mm long, 1.5 mm thick, limb
broadly ovoid, to about 2 mm long and wide, apex obtuse to
broadly rounded or subtruncate, lobes not yet started to open.
ovate to oblong; fruit unavailable.
This species known only from its type, from Kusaie, seems
related, by the fomi of its inflorescence and stipules, to
Psychotria cheathamii from Palau. Its habit, leaf-shape, and
size of its parts set it off from that species. The type specimen
lacks open flowers and fruits, so its characterization is
incomplete.

Shrubby tree or shrub (originally described as “Herba”),
generally, except upper leaf surface, dark brown woolly-
hirsute, intemodes 1.5-5 cm; leaves lanceolate, to 16 x 3 cm,
prominently acuminate, base acute, somewhat decurrent on
petiole, nerves 10 to 14 on a side, strongly ascending, upper
surface glabrous, lower hirsute especially on nerves, petiole
10-15 mm; stipules prominently sheathing-cylindric, 1-1.5
cm long lacerate above into a number of lanceolate-caudate
segments, these irregularly pectinately-bristly-ciliate, persis-
tent but gradually weathering off; inflorescences axillary
capitula or compound capitula, involucrate with complicated
deeply lacerate bristly-woolly bracts; calyx prominent, deeply
cut into lanceolate woolly lobes, corolla; and other flower parts
not seen, corolla said to be red; fruit about 6 x 2.5 mm,
subcylindric, strongly ribbed when dry, crowned with persis-
tent calyx, described when fresh as red, fuzzy or with white
hairs.
A strikingly distinct species not close to any other
Micronesian species. Endemic to Ponape, so far as known,
mostly inhabiting high wet mountain ridges. Perhaps related to
P. guilloveana Baillon of New Guinea.

Psychotria leptothyrsa Miquel
Psychotria leptothyrsa Miquel, Ann. Mus. Bot. Lugd., 4:208, 1868. — Fosberg,
Allertonia, 6:258, 1991.
Shrub or small tree to 6 m tall, glabrous; leaves narrowly to,
rarely, very broadly elliptic, 5-25 x 1-15 cm, acuminate to
rarely acute or rounded at apex, base acute to decurrent-
contracted, thin, usually drying light green, secondary veins (5)
8 to 12 on a side, lesser veins and network inconspicuous to
obscure, petiole 1.5 or less to 4.0 (-5.0) cm long; stipules
forming a low scarious collar with a mucro on each side, very
early caducous, scar tending to enlarge and become corky, a
row of hairs or colleters in axil; inflorescence thyrsoid, terminal
or axillary, from very long and lax to variously reduced, even
to a single (surviving) flower or fruit, branches opposite or
whorled, distally often irregularly branched, with minute
subulate or triangular caducous bracts, flowers pedicellate;
calyx broadly cup-shaped to flaring, subentire to obscurely
lobed or denticulate, thin; apparently heterostylous but short-
styled greatly predominant at least in Micronesian specimens,
corolla tubular, tube (2-) 4-8 mm long, not or slightly
ampliate upward, visibly veined, pilose within especially in
throat, lobes shorter about 2 mm long, ovate, apex of bud
rounded to subtruncate; anthers broadly linear, usually exserted
from tube, rarely included; style deeply bifid, shorter than
corolla tube or, rarely, exceeding it, disk prominent, rounded;
drupe ovoid to globose, or obovoid, sulcate when dry, obtuse or
rounded to truncate; pyrenes sharply 3-carinate; seed with
homogeneous endosperm, not at all ruminate.
One of the most plastic of species, varying in practically
every character, even within the varieties, extremes scarcely
seeming to belong to the same species. Probably separable into
many geographical varieties, but very few non-Micronesian
specimens available to us. Three discernible varieties in the
central and western Caroline Islands, one in Palau, one in Yap,
one in Truk, these overlapping in most characters. The
geographic range of the species is Indonesia and Philippines to
New Guinea and Caroline Islands, and probably still wider;
originally described from the Moluccas.

Shrub or small tree to 5 m tall; leaves elliptic or i
oblong-elliptic, 10-20 or up to 30 cm long, strongly acuminate,
membranous, 8 to 14 veins on a side; stipules triangular,

Differing notably in its stipules, triangular, not low
collar-like, but which as in other varieties, are very early f
caducous, and in the shape of its fruit, which is not notably
truncate. Apparently endemic to Tol Island, Truk, found only '
on summit and upper slopes of its highest peak.

Psychotria leptothyrsa var. yapensis Fosberg
Psychotria leptothyrsa var. yapensis Fosberg. Allertonia, 6:260, 1991.
Shrub, leaves small to medium, not or seldom, more than 15
X 5 cm, varying to elliptic lanceolate, 5 to 8 veins on a side,
thyrses loose even when small, mostly about 4 or less rarely to
10 cm; flowers with corollas 3-5 mm long; fruits small, 6-7 x
5-6 mm, broadly obovoid — cup-shaped, truncate distally.
So far as known endemic to Yap, probably all Yap plants of
P. leptothyrsa belong here. In fruit size (and shape) this variety
seems closest to var. leptothyrsa, but the small flowers and
small, few-flowered thyrses, as well as the smaller leaves with
fewer veins, seem to justify separation. More collections with
special attention to flower size and to whether flowers are
heterostylous are very much needed.

Shrub or small tree, glabrous or almost so, branches cylindric
dark gray or gray-brown to light gray, branchlets slender,
lowest intemode of branchlet to as much as 8 cm long, distally
progressively much shorter; leaves tending to be crowded at
ends of branchlets, chartaceous to subcoriaceous, obovate to
elliptic, shortly acuminate, 6-10 (-12) x (2-) 3-4 (-5) cm,
usually narrower, base cuneate or acutely contracted, nerves 6
to 12 on a side, not prominent, petiole rather slender, 1-2.5 cm
long, stipules connate, forming a fusiform calyptra enclosing
terminal bud and primordia, opening down one side and
caducous, apex with 2 or 4 short aristate appendages (lost from
most specimens), not carinate or plicate, glabrous; cymes in
upper axils, trichotomous or rarely twice trichotomous, slender
or almost filiform, flowers subsessile, in triads ending
cyme-branches; calyx rather turbinate minutely 4-denticulate;
corolla with 4 lobes almost as long as or longer than tube, throat
bearded; drupe red, to 6-8 mm long, pyrenes more or less
tricarinate, rugose.
A member of the widespread Pacific group of Psychotria,
characterized by the terminal buds and inflorescence primordia
enclosed by calyptrate caducous stipules. It seems indeed
related to P. arhuscula Volkens of Yap, as stated by Merrill,
but not so close to P. viridifiora, or P. insularis. However, it is
closer to P. hombroniana (Baillon) Fosberg, where we had
placed it as a variety, until we had studied closely the stipular
arrangement. The calyptrate stipules, as contrasted with the
sheathing, strongly bifid ones of P. hombroniana, seem ample
reason for maintaining P. malaspinae as a separate species.

Psychotria gaudichaudii Kanehira, Bot. Mag. Tokyo, 48:926, 1934; Enum.

Shrub or small tree, glabrous, intemodes on flowering
branchlets very short; leaves 8-10 (-14) x4-6 (-7) cm, thinly
coriaceous, usually showing a rose or purplish tinge when
dried, obovate to elliptic, obtuse to bluntly acute or broadly
short acuminate, main veins 7 or 8 on a side, blade narrowed to
a short petiole; stipules ovate, flat in middle of dorsal side,
slightly carinate distally, connate in lower third or half, early
caducous, axils stiffly hirsute; cymes terminal, pedunculate,
trichotomous, subthyrsoid, widely branching about 5 times or
less, stiff, hemispherical to corymbiform when well developed,
a pair of scale-like bracts at each articulation; hypanthium
glabrous, calyx limb prominent funnelform or slightly campa-
nulate, from essentially truncate to shallowly crenate or
obtusely lobed, splitting tardily into irregularly ovate lobes,
persistent on fruit; corolla hypocrateriform, tube cylindric, up
to 6 mm long, lobes 5, oblong, reflexed, throat densely barbate;
anthers exserted, at least partially, erect; style well exserted,
glabrous, stigma fusiform, tip bifid; fruit subglobose, red,
fleshy, crowned with prominent cup-like calyx, pyrenes 2,
inner face flat, outer strongly convex, with no trace of ribs; seed
with endosperm deeply ruminate.
This species is perplexingly variable in a number of
characters, e.g., leaf size, outline, and apex, length of petiole,
size, shape and degree of branching of the inflorescence, lobing
of calyx, etc., but there is no correlation between these
variations or in their geographic localization. Until quantitative
field studies are done there seems no basis for separation into
infraspecific taxa. Psychotria gaudichaudii Kanehira was
based on material from Sarigan and Rota. It does not seem to
differ significantly, though there seems to be a tendency toward
narrower, more acute leaves northward in the Marianas, but this
is too vague to merit any nomenclatural recognition. Psychotria
rotundifolia Valeton was likewise based on Sarigan material,
but this is described as having leaves very broad, almost
suborbicular. It seems to represent the opposite extreme in the
variation in this species. If these were recognized as taxa, the
results would be that in some cases two taxa would be found on
the same plant.
The form of the stipules, the nature of the inflorescences, and
especially the notably ruminate endosperm place this species in
the subgenus Grumilea, well developed farther west.

long, up to 7.5 cm wide, material with larger leaves seen,
including that described as Plectronia potyneura, and at least
part of syntype material of Pyschotria merrillii, glabrous or
sparsely puberulent or hirtellous, especially along the nerves
beneath, nerves prominent, 8 to 10 (16) on a side, petioles
1-2.5 (-3.0) cm; stipules calyptrate, to at least 13 mm long,
early caducous with expansion of inflorescence, with 2 free
mucronate terminal appendages; flowers in 6- to 12-flowered
fascicles terminal becoming pseudoaxillary, pedicels (very
rarely branched ?) slender, glabrous or puberulent, up to 10
(rarely 18) mm, long hypanthium glabrous or hirtellous, calyx
widely spreading saucer-shaped, even in bud, with 5 very short
subulate teeth; corolla white, in bud with rounded apex, at
anthesis tube 1.5-3. 5 mm long, bearded in throat, 5 lobes
ovate, 2. 5-4.5 mm, with a thick hook-like appendage inside
apex; disk prominent, entire, flat-topped; style glabrous,
apparently subequal with corolla-tube; drupe red when mature,
narrowly ovoid, about 5-6 (-10) mm long, pyrenes apparently
tricarinate dorsally, glabrous or pubescent.
This is a typical member of the widespread Pacific group of
Psychotria, characterized by calyptrate stipules usually ap-
pendaged at summit, and early caducous. Apparently endemic
to Ponape.
This species seems quite uniform in leaf shape, stipules,
inflorescence, flowers and fruit, except for variation in leaf size.
The distribution of puberulence, however, is variable. Some
specimens (nos. 9521, 5592, 8203, 5973, 13790, 13274, 2352,
13790) are quite glabrous. Others (nos. 2010, 13829) have
puberulence along the midrib on the under sides of leaves. Still
others (nos. 13689, 1618, 2501, 26425) have the leaves
puberulent beneath, especially along midrib, and the hypan-
thium, sometimes the pedicels, and the fruit notably hirtellous.
These variations all seem to occur together on the mountain
tops and ridges. The one designated here as lectotype of
Plectronia obovata Valeton, Ledermann 13790 (B) is glabrous.
The specimen described by Valeton as Plectronia polyneura,
Ledermann 13814, we have not seen, but from a photo, appears
to represent a separate taxon. It is maintained here as a variety
and is discussed below.

Leaves elliptic to somewhat obovate, 15-17 x 7-7.5 cm,
petioles 20-30 cm, pedicels many in fascicles in uppermost
axils, rufo-villosulous, 5-10 mm, hypanthia villosulous; calyx
glabrous, teeth acute, corolla about 4 mm long, velutinous
within at base.
This has been considered synonymous with Psychotria
merrillii by Kanehira and by Fosberg, neither of whom had
seen the type, Ledermann 13814, which was probably
destroyed in the bombing of the Berlin herbarium. However, a
photo of this specimen was published by Kanehira in 1935
(photo 3). This, while not too well reproduced, shows a plant
that has larger leaves with more veins than the plant described
as Plectronia obovata Valeton. Valeton gives ±16 for
Plectronia polyneura. Valeton’s description of P. obovata
gives the number of veins as 10 to 12 on a side, and Kanehira,
for Psychotria merrillii, gives 8 to 10, to 11 in his fig. 197,
1933. Material available to us has, with two exceptions, 8 to 10
veins on a side. The exceptions are Stone 2010, with 8 to 12,
and Kanehira 1618 with 11 or 12 so far as can be seen without
damaging the specimen. We choose to maintain Plectronia
polyneura as a distinct taxon in Psychotria but at the rank of
variety. This may direct attention to it and future collections
may settle whether or not it represents a population, or if the
variation is continuous. The two collections mentioned above.
Stone 2010 and Kanehira 1618, we treat as intermediates closer
to var. merrillii.

A very disinct species not much resembling any other, at
least in Micronesia. Apparently endemic to Rota and Palau.
Guam specimens reported or named as this were misidentified.
We have seen an excellent sheet of Hosokawa 7476, reported as
this from Palau, but he later described this as P. palauensis
Hosokawa, which we have reduced to varietal rank under P.
rotensis Kanehira. The above description refers to var. rotensis.

This variety is, so far as known, endemic to the island of

specimens on which they were based, to be misidentified
members of the P. hombroniana relationship.

Herbs and small dwarf shrubs, stems tending to be square,
often with cord-like angles, most parts of plants with few or
many rhaphid-bundles showing through the epidermis, roots
often wiry or somewhat woody, forming stiff root-crowns;
leaves simple, entire, opposite, decussate, usually not more
than 5-7 cm long, in some species appearing fasciculate
because of reduced leafy branches in leaf axils; stipules
interpetiolar, usually somewhat united below or adnate to leaf
bases, margins often pectinate with linear or setiform proc-
esses, or dentate; inflorescences usually of strongly condensed
axillary cymes forming few-flowered or usually many-
flowered verticels, the terminal ones often larger and appearing
older, capitate; flowers usually sessile or subsessile; hypan-
thium cylindric, prismatic or turbinate, crowned by a calyx with
4 lobes or teeth, one pair often reduced or vestigial, united base
of calyx usually very short; corolla white, lavender or bluish,
tubular or campanulate, subequal with calyx to strongly
exserted, 4-lobed; stamens 4, inserted below sinuses, anthers
included or exserted; style filiform, bifid and stigmatic at apex,
ovary bilocular with one ovule in a locule; fruit a capsule,
dehiscing variously, basically septicidal, one cell may not open,
or both cells open septicidally, leaving an erect hyaline septum
(this in one species separating into 2 thin layers and loosening),
or splitting first down one side and opening out to shed seed, or
after separating into cocci the cells opening by splitting
ventrally; seed one to a cell, cylindric to ovoid or ellipsoid, with
a deep, wide or narrow ventral groove, this either open or
closed at ends, testa smooth or variously reticulate, rugose or
sulcate.
In the sense accepted here, a pantropical and subtropical
genus of many species, not well known, some of them very
weedy and widespread, resembling in habit some species of
Hedyotis. Six species are known from Micronesia, all of them
introduced. The most reliable characters to separate them are in
the seeds. The key presented here is based partly on vegetative
features, used because seeds and flowers are not always
present.

Erect to reclining herb, tending to branch at base, usually
2-3 (-5) dm tall, intemodes with 4 sharp keels and 2 deep
groves, keels usually notably retrorsely appressed hispidulous
or hirsutulous, stems and sometimes leaves tending to be
reddish; leaves broadly lanceolate, lance-ovate, or lance-elliptic
to broadly ovate or elliptic, up to 6 x 2 cm, apex acute to
acuminate, base acute, shortly petiolate to subsessile, strongly

surfaces, becoming reflexed where subtending inflorescences;
stipules forming a sheath, to 3 mm long, dialated upward,
pectinate with 5 to 7 setiform appendages on a side, these well
separated at base, this sheath densely or sparsely appressed
pubescent, often in lines, greatly swollen and stretched by
development of dense head-like inflorscences at nodes, these
subtended by two leaves at a node and usually additionally by
2 smaller bracteal leaves, all becoming reflexed; heads packed
with setae, presumably stipular in nature, equalling hypanthia;
flowers with hypanthium pubescent, calyx lobes 4, triangular-
acute to linear-oblong, subulate, blunt, or expanded and
rounded and varying greatly in length and width; corolla white
or pinkish, strongly exserted, with a very narrow tube, a very
short campanulate or funnelform throat, and 4 oblong lobes,
hispidulous without near tips, pilose within, the whole about
4-6 mm long, buds oblong-ellipsoidal; anthers oblong to oval,
strongly exserted on filiform filaments; filiform style and
capitate stigma greatly exceeding corolla, to about 6 mm, fruit
obovate or turbinate, 4-5 mm long, strongly pubescent above,
septicidally, then slightly loculicidally, dehiscent, leaving an
ovate, acute, stiff, white septum erect between valves; seed
dark dull brown, plumply ellipsoid with usually blunt ends,
deeply and conspicuously transversely sulcate, and minutely
reticulate especially at ends.
Pantropical species, probably of American origin, now on
many Pacific Islands, including Marianas, western Carolines,
and Gilberts; weedy, found in disturbed places, along paths and
roadsides. Has traditionally, but incorrectly, been called
Borreria laevis.

Slender herb, sprawling, decumbent to erect, rooting at lower
nodes, yellow-green in appearance, even when dried, stems
sharply quadrangular to sub-alate, thinly to notably retorse-or
spreading-hirsute; leaves to 5-6 x 3-3.5 cm, broadly elliptic to
slightly ovate, thin, apex acute, base acute, somewhat decurrent
on the short petiole, up to 1 cm, mostly shorter, blades sparsely
to notably appressed hirsute on both sides, veins about 5 or 6,
slightly arched forward; stipules membranous, low-sheathing,
hirsute-pilose, pectinate with setiform processes, these sparsely
long-hirsute-pilose, especially near apex; inflorescences very
dense, crowded but usually rather few-flowered, crowded with
linear or lanceolate bracts, and hypanthia, calyx lobes
triangular ovate to oblong ovate, or almost lanceolate,
persistent; corolla about 3-5 mm long, very thin, ephemeral,
shed easily, tube very slender, about equalling or exceeding the
campanulate throat and ovate lobes; stamens and style about
subequal with corolla, or style slightly longer, glabrous;
capsule broadly ovoid to subglobose, 2.5-3 x 2 mm, hirsute,
crowned by persistent calyx lobes, thin-walled, dehiscing
septicidally into 2 cocci that then split ventrally the length of
the thin half of the septum, then somewhat loculicidally,
opening widely to release the seeds, superficially resembling a
circumscissile-dehisced capsule (frequently under pressure
during drying the capsules may fracture transversely, again
simulating a circumscissile dehiscence); seed somewhat ovoid
broadly oblong-elliptic, ends rounded, 2.5-3 x 1.6-2 mm,
light drab brown to black, dorsally convex, surface minutely
reticulate-rugulose, ventrally flattened, groove wide, deeply
excavate, the ends closed, margins appearing inrolled, a large
elongate white scar in bottom of excavation, narrower than
groove.
This plant has generally been called Spermacoce ox Borreria
latifolia, which it resembles. The delicate, fugacious corolla
with a slender tube seems wrong for that species, or for the
similar S. alata Aublet. It is also more hirsute than either of
these.
Widespread in the Indo-Pacific, from India and Ceylon to
Fiji, Palau, and Ponape, but probably introduced from tropical
America.

sheath very short, 1 mm or less, much exceeded by the setiform
pectinately arranged segments, these scarcely puberulent, not
or scarcely gland-tipped, 8 or more on a side, sheath
puberulent; inflorescences capitate, axillary few to many-
flowered, flowers subtended by filiform stipular bracts but
these not conspicuous; hypanthium almost glabrous to hispidu-
lous, calyx-lobes 4, linear or lance-linear, equal to somewhat
unequal, hispidulous-ciliate near base, subacuminate; corolla
shorter than or subequal to calyx, tube very short, lobes
triangular-ovate, minutely puberulent without, subglabrous or
puberulent within but base of lobes and throat pilose-bearded;
anthers subsessile, attached in tube, broadly oval, bluish or
blackish; style exceedingly short, stigma bilobed; fruit broadly
obovoid to broadly cylindric, very slightly compressed, more
or less hispidulous, about 1.5 mm long, dehiscing septicidally,
one side more tardily than the other, so that capsule valves tend
to spread from one side, septum membranous, ephemerally
thin; seed broadly, to rarely narrowly, elliptic, about 1-1.5
(-1.7) mm long, groove very wide, extending full length of
seed, with a prominent row of raphide bundles along each side,
dorsal surface, when mature, glossy, castaneous, shallowly
alveolate-reticulate.
A widespread tropical American species, introduced in the
Pacific probably during or shortly after World War II, which
since then has become fairly widespread at least in the central
and western archipelagoes; known in Micronesia from the
Marianas (Saipan, Rota, and Guam), from the Carolines
(Palau), and from the Gilberts (Tarawa). It has become
common on roadsides and in disturbed places, frequently in
semi-shade. It is usually known in tropical America as Borreria
ocymoides, which it only resembles in its small corolla, not
exceeding the calyx.

hispid to pilose, especially on prominent angles; leaves
ovate-lanceolate to elliptic; oblong or obovate, obtuse to acute,
moderately to sparsely hirsute on both surfaces, narrowed to a
subsessile or sessile base; stipules membranous, 2 mm high,
hirsute, with ciliate margins pectinate with about 5 to 7
filiform, glabrous or slightly hirsute, gland-tipped setae with
triangular widening at base; verticels rather few-flowered,
younger ones distal; hypanthium and calyx densely hirsute,
hairs flattened, calyx lobes 4, linear-lanceolate, unequal, 2
tending to be longer, hirsute, fruit densely hirsute, or almost
glabrous toward base, dehiscing apically toward base, leaving
a scarious septum; seed elliptic to elliptic -oblong, 2.5-3. 5 mm
long, minutely rugose, rather convex, ends rounded, groove
ends open but sometimes appearing semi-closed.
This species, common in south and central Asia, was
collected twice in 1 9 1 3 on Ponape, but has not been found there
since. One of these collections was described as a separate
species, Borreria rotundifolia Valeton, but seems, at best,
varietally distinct from Spermacoce hispida L. The Yap record
of this species based on Volkens 215, is now referred with some
doubt to Spermacoce mauritiana Gideon. That from Guam, by
Walker and Rodin (1949), based on Rodin 527, is Mitracarpus
hirtus (L.) de Candolle.

Weak, slender, erect to usually reclining or prostrate herb,
stems sharply quadrangular, the angles notably ciliate, the
intervals glabrous; leaves broadly ovate, or elliptic, apex
acutish or acute to obtuse, base gradually to usually abruptly
contracted to a short petiole, blade 1-1.5 (-2) x 0.4- 1.0 (-1.5)
cm, glabrous to sparsely scabrous or puberulent, especially
margins; stipules very low, 1 mm or less high, pectinate with
usually about 6 to 8 setae about 1.0- 1.5 mm long, these
scarcely or rarely glandular at tip; inflorescences capitate,
densely rather few-flowered, flowers subtended by setiform
bracts; hypanthium papillose-puberulent, together with calyx
scarcely 1.5 mm long, calyx lobes 2, lance-subulate, scarcely
ciliolate (rarely traces of another reduced pair), persistent in
fruit; corolla white or rarely pinkish, urceolate, 0.6-0. 8 mm
long including the erect spreading ovate-triangular lobes, these
about half the length of the corolla, pilosulous within; anthers
minute, sessile; style and stigma included; fruit puberulent,
slightly obovoid to globose, septicidal into two deeply concave
valves; seeds oblong about 1 mm long, dull medium somewhat
yellowish or reddish brown, transversely reticulate, cells or
areolae notably broader than high.
This pan-tropical weedy plant is probably of New World
origin and an early introduction into the Asiatic tropics. The
closest relative of S. mauritiana. seems to be S. prostrata
Aublet, a widely distributed New World plant that has also
usually been called Borreria ocymoides. The two are very
similiar, but may be distinguished by the shape, color, and
NUMBER 81
121
sculpturing of the seeds, those of S. mauritiana being dull
yellowish or reddish brown, often somewhat flatter and more
oblong, and finely transversely reticulate, while those of S.
prostrata are usually mahogany brown, somewhat glossy, more
cylindric and prominently more coarsely alveolate-reticulate.
The leaves of 5. mauritiana are usually broadly ovate or
broadly elliptic, and its corolla lobes are pilose, while S.
prostrata usually, but not always, has narrower elliptic leaves,
narrowed gradually to base, and its corolla lobes only papillose
or minutely puberulent within.
African specimens of this species, including the type, Sieher
in 1835 (G-DC) from Mauritius, and possibly a few American
ones, such as Buchtein 1414 (US), from Bolivia, Mapiri region,
San Carlos, have the sharp angles of the intemodes notably
ciliate. They seem to be varietally distinct from the common
American plant. Micronesian specimens agree with the type.

strongly veined, usually (or always?) petiolate; stipules thin to
firm, usually acuminate, connate and sheathing at base; flowers
axillary, the pistillate solitary or in few-flowered cymes, the

An Indo-Pacific genus with many species, a few in
Micronesia.
Some of the Micronesian species are difficult to distinguish,
especially without material of both sexes collected at the same
time and place. The morphology of the gynoecium of some
species is very aberrant in the Rubiaceae and needs compara-
tive study of many species, preferably with ample material for
dissection.

lateral flower closely subtended by 2 to 4 minute bractlets;
pistillate flowers with hypanthium about 2 mm long, calyx
urceolate, the 4 triangular teeth spreading somewhat, persisting
on fruit; corolla tube 5-6 mm long, somewhat dilated upward
or not, glabrous within, densely sericeous without, lobes also,
these 4 (-5), ovate 2-2.5 mm long, spreading or reflexed, 2
bands of papillae within, antherodes linear, sessile in throat;
style with 2 or more flattened branches, these irregularly
tridentate or slightly trifid, then again dentate, apical parts of
branches somewhat exserted; fruit globose, 5-7 mm diameter
when dry, irregularly mammillate, pyrenes 16 or more,
radiating-ascending in vertical rows, fusiform and slightly
curved, free.
Found on Olopshacal (= Aulupse’el) Island, northernmost of
the large limestone islands of Palau, Arimasuku, Kaiguru,
Peleliu, and Angaur. In leaf characters this variety resembles T.
korrense, but the staminate inflorescences are much more
slender, more times ramified, and the flowers much smaller;
pistillate cymes more slender, more branched, placing it in T.
corymhosus.

Micr. PI., 426, 1935.
Small tree, generally .sparsely to densely villous-hirsute, only
sparsely so on upper leaf surfaces (more densely on principal
veins), intemodes mostly short; leaves broadly elliptic to
usually broadly obovate, up to at least 27 x 15 cm, thin, apex
acuminate, base cordate-auriculate, usually unequally so,
nerves 9 to 1 1 on a side, prominent, anastomosing distally in a
weak submarginal vein, network between nerves inconspicu-
ous, petiole thick, 1 (-1.5) cm or usually less long, densely
hirsute; stipules straight, ovate, strongly acuminate, up to 15
mm long, soon caducous; staminate cymes dense, subcapitate,
at most 2 cm long, shortly pedunculate, at least twice ramified,
about 1 1 -flowered, densely short-hirsute, flowers in bud only,
buds ellipiosidal, hirsute, calyx lobes lanceolate unequal;
pistilate flowers on short peduncles (to 10 mm) or subsessile,
hypanthium subglobose, calyx deeply parted into 6 linear lobes
3-12 mm long, corolla up to 15 (-17) mm long, cut about '/3
into 6 lance-ovate lobes; fruit globose to depressed globose, up
to 15-18 mm wide, 12 mm high, pubescent.
The type of T. mollis, Ledermann 14342, from Palau,
Babeldaob, Ngarsul, consisting of 2 pieces mounted on the
same sheet, adequately described by Valeton, was probably lost
in the destruction of the Berlin Herbarium. A duplicate could
conceivably exist in another herbarium.
Timonius tomentosus was published by Valeton in his key to
the Micronesian species, but in the text T. mollis was used. T.
tomentosus was probably a lapsus on Valeton’s part, but was
published with descriptive material in the key. Since he did not
accept it, apparently, it is invalidly published (Art. 34, ICBN).
Apparently endemic to Palau, except that a sterile specimen
collected by Otto Swezey on Guam may be a seedling of T.
mollis.
Three varieties should be recognized, a small-leafed,
small -flowered one corresponding to Valeton’s species, and a
larger leafed, larger flowered one corresponding to Kanehira’s
T. villosissimus represented, at least, by Takamatsu 1623, and
an intermediate one approaching T. suhauritis.
Geographic Record and Specimen Examined

Timonius mollis Valeton var. mollis

Pubescence rather prominent, spreading, leaves thin, elliptic,
acuminate, cordate at base, blade, especially the veins,
somewhat hirsute, more so beneath, petioles densely hirsute,
fruit densely strigose.

(This is a seedling with similarly reflexed stipules to the Swezey

Timonius mollis var. submollis Fosberg & Sachet
Timonius mollis Val. var. submollis Fosberg & Sachet, Micronesica, 20:161,

Leaves tending to be firm, pubescence thin, subspreading to
appressed, leaf bases obtuse to subcordate, calyx lobes,
especially of staminate flowers, lanceolate, fruit minutely
strigulose, fruiting peduncle 1.5-4 cm.
This variety seems almost intermediate with T. suhauritus
but its lanceolate calyx lobes suggest that it belongs with T
mollis.

Whole plant much more conspicuously hirsute than in var.
mollis, hairs generally spreading, tending to be somewhat
matted on stems, petioles and main veins, and to be appressed
on flowers and fruits, fruit densely silky-strigose.
The characters used by Kanehira to distinguish his species
from T mollis, larger leaves and fruits and longer pedicels, do
not hold up with more specimens than were available to
Kanehira. We do not find these characters at all reliable, but the
much denser and more conspicuous pubescence seems to
justify at least varietal separation, contrary to the opinion
expressed earlier (Fosberg, 1940). A specimen of the lectotype
collection at K bears an apparently unpublished name by
Kanehira, based on the name of the type locality.

This differs in its notably strigose young growth, leaf veins
and petioles. In its hairiness and thinner leaf texture it
approaches T mollis, especially T. mollis var. submollis.
It is known only from Palau, Babeldaob Island, especially in
Airai Municipality.

Uncaria Schreber
Uncaria Schreber. Gen. PI., 1:125, 1789 [Norn. Cons.].
Lianas with a main stem and differentiated (plagiotropic)
branches originating supra-axillarily from the main shoot,
producing reduced leafless lateral branchlets that either become
recurved forming hooks or act as peduncles that bear the
“heads,” usually really many-flowered umbels, flowers sessile
or usually pedicellate, sometimes conspicuously so, bracteolate
or not, heads or umbels subtended by stipular bracts, leaves
opposite, pinnately few veined, often with domatia in vein
axils; stipules entire to bifid, those forming stipular bracts
sometimes foliaceous, with glands (colleters) at base inside;
flowers always borne in heads or umbels, 5-merous, calyx tube
short, 5 lobes various, sometimes with diminutive secondary
lobes (epicalyx) alternating with them; corolla funnelform to
hypocrateriform, lobes valvate or sub-imbricate; stamens
inserted in upper part of corolla tube, anthers well exserted,
spreading; style longer than corolla tube, stigma exserted,
globose to turbinate; ovary 2-locular, placentas axile, attached
to septum in upper part, ovules many, imbricate upward; fruit
a septicidal (later somewhat loculicidal) capsule; seeds with a
wing on each end, the lower one bifid.
A pan-tropical genus, with most species in the Indo-
Malaysian region, one in Micronesia, related to, sometimes
regarded as a variety of a Malesian one.

Uncaria lanosa var. korrensis (Kanehira) Ridsdale, Blumea, 24:88, 1978.
Vine, stems square, glabrous except pilose in axils of
stipules, branching very slightly supra-axillary, leaves broadly
ovate to broadly elliptic, to 8 x 4 cm, acuminate, base obtuse to
rounded, blade thin, glabrous except for a few hairs on upper
side of midrib, veins 5-6 on a side, petiole slender 5-6 mm
long; stipules early caducous, bracteal ones red, somewhat
bifid; nodes either bearing axillary branchlets or these modified
into recurved or even coiled spines, unmodified ones with a
node about ^4 the way up, the part below the node curved,
glabrous, the part above slender, brown sericeous, bearing a
globose receptacle with many short villous pedicels, these
enlarging upward into fusiform ovaries, appressed villous
below or to summit, crowned with 5 lanceolate-subulate
filiform, pilosulous pink calyx lobes; corolla pinkish yellow,
with filiform tube 6-8 (-10) mm long, lobes oblong to broadly
oval about 2 mm long, apices rounded, outer surfaces minutely
puberulent, margin tending to be revolute; anthers ovate-
lanceolate to oblong, apex blunt; style glabrous filiform, long
exserted, stigma clavate; fruit narrowly fusiform, up to 1 cm
long, dehiscing only septicidally, valves eventually opening
out flat, not or scarcely split at apex; seeds including narrowly
lanceolate white wing 4-5 mm long, body sub-orbicular,
0. 2-0.3 mm long, dull brown, muriculate.
Ridsdale has made this one of many varieties of the Malesian
U. lanosa Wallich, which he constmes in a very broad sense,
which may be justified. However, he discusses only the calyx
and hypanthium characters. Since we have no material
available of U. lanosa. sensu stricto, and have not seen a
modem description of it, we will continue to treat U. korrensis
as a separate species, endemic to Palau. We give a rather full
description so that it can be compared in detail. Ridsdale has
also reported U. lanosa f. appendiculata from Micronesia on a
sterile specimen on which he gives no other data, locality or
collector.

REQUIREMENTS FOR SMITHSONIAN SERIES PUBLICATION
Manuscripts intended for series publication receive substantive
review (conducted by their originating Smithsonian museums or
offices) and are submitted to the Smithsonian Institution Press
with Form SI-36, which must show the approval of the appropriate
authority designated by the sponsoring organizational unit. Re-
quests for special treatment — use of color, foldouts, case-bound
covers, etc. — require, on the same form, the added approval of
the sponsoring authority.
Review of manuscripts and art by the Press for requirements
of series format and style, completeness and clarity of copy, and
arrangement of all material, as outlined below, will govern, within
the judgment of the Press, acceptance or rejection of manuscripts
and art.
Copy must be prepared on typewriter or word processor,
double-spaced, on one side of standard white bond paper (not
erasable), with VA" margins, submitted as ribbon copy (not
carbon or xerox), in loose sheets (not stapled or bound), and
accompanied by original art. Minimum acceptable length is 30
pages.
Front matter (preceding the text) should include; title page
with only title and author and no other information, abstract page
with author, title, series, etc., following the established format;
table of contents with indents reflecting the hierarchy of heads in
the paper; also, foreword and/or preface, if appropriate.
First page of text should carry the title and author at the top
of the page: second page should have only the author’s name
and professional mailing address, to be used as an unnumbered
footnote on the first page of printed text.
Center heads of whatever level should be typed with initial
caps of major words, with extra space above and below the head,
but no other preparation (such as all caps or underline, except for
the underline necessary for generic and specific epithets). Run-in
paragraph heads should use period/dashes or colons as neces-
sary.
Tabulations within text (lists of data, often in parallel columns)
can be typed on the text page where they occur, but they should
not contain rules or numbered table captions.
Formal tables (numbered, with captions, boxheads, stubs,
rules) should be submitted as carefully typed, double-spaced copy
separate from the text; they will be typeset unless otherwise
requested. If camera-copy use is anticipated, do not draw rules
on manuscript copy.
Taxonomic keys in natural history papers should use the
aligned-couplet form for zoology and may use the multi-level
indent form for botany. If cross referencing is required between
key and text, do not include page references within the key, but
number the keyed-out taxa, using the same numbers with their
corresponding heads in the text.
Synonymy in zoology must use the short form (taxon, author,
year;page), with full reference at the end of the paper under
“Literature Cited." For botany, the long form (taxon, author,
abbreviated journal or book title, volume, page, year, with no
reference in "Literature Cited”) is optional.
Text-reference system (author, year:page used within the text,
with full citation in "Literature Cited” at the end of the text) must
be used in place of bibliographic footnotes in all Contributions
Series and is strongly recommended in the Studies Series:
“(Jones, 1910:122)" or “...Jones (1910:122)." If bibliographic
footnotes are required, use the short form (author, brief title, page)
with the full citation in the bibliography.
Footnotes, when few in number, whether annotative or biblio-
graphic, should be typed on sepa/ate sheets and inserted imme-
diately after the text pages on which the references occur. Exten-
sive notes must be gathered together and placed at the end of
the text in a notes section.
Bibliography, depending upon use, is termed “Literature Cited,"
“References," or “Bibliography.” Spell out titles of books, articles,
journals, and monographic series. For book and article titles use
sentence-style capitalization according to the rules of the lan-
guage employed (exception: capitalize all major words in English).
For journal and series titles, capitalize the initial word and all
subsequent words except articles, conjunctions, and prepositions.
Transliterate languages that use a non-Roman alphabet according
to the Library of Congress system. Underline (for italics) titles of
journals and series and titles of books that are not part of a series.
Use the parentheses/colon system for volume (number):
pagination: “10(2):5-9." For alignment and arrangement of ele-
ments, follow the format of recent publications in the series for
which the manuscript is intended. Guidelines for preparing bibli-
ography may be secured from Series Section, SI Press.
Legends for illustrations must be submitted at the end of the
manuscript, with as many legends typed, double-spaced, to a
page as convenient.
Illustrations must be submitted as original art (not copies)
accompanying, but separate from, the manuscript. Guidelines for
preparing art may be secured from Series Section, SI Press. All
types of illustrations (photographs, line drawings, maps, etc.) may
be intermixed throughout the printed text. They should be termed
Figures and should be numbered consecutively as they will
appear in the monograph. If several illustrations are treated as
components of a single composite figure, they should be desig-
nated by lowercase italic letters on the illustration; also, in the
legend and in text references the italic letters (underlined in copy)
should be used: “Figure 9b.” Illustrations that are intended to
follow the printed text may be termed Plates, and any components
should be similarly lettered and referenced: “Plate 9b." Keys to
any symbols within an illustration should appear on the art rather
than in the legend.
Some points of style: Do not use periods after such abbrevi-
ations as “mm, ft, USNM, NNE.” Spell out numbers “one” through
“nine” in expository text, but use digits in all other cases if possible.
Use of the metric system of measurement is preferable: where
use of the English system is unavoidable, supply metric equiva-
lents in parentheses. Use the decimal system for precise meas-
urements and relationships, common fractions for approximations.
Use day/month/year sequence for dates: “9 April 1976.” For
months in tabular listings or data sections, use three-letter abbre-
viations with no periods; “Jan, Mar, Jun,” etc. Omit space between
initials of a personal name: “J.8. Jones."
Arrange and paginate sequentially every sheet of manu-
script in the following order: (1) title page, (2) abstract, (3) con-
tents, (4) foreword and/or preface, (5) text, (6) appendixes, (7)
notes section, (8) glossary, (9) bibliography, (10) legends, (11)
tables. Index copy may be submitted at page proof stage, but
plans for an index should be indicated when manuscript is sub-
mitted.
