i. THE JAMAICAN SPECIES OF HERNANDIA
On March 20, 1908, while exploring a wooded hill near Dol-
phin Head Mountain, parish of Hanover, in the western part of
Jamaica, in company with Mr. William Harris, we observed large
trees which were unknown to us from the character of their trunks,
and too high to enable us to determine the character of their foli-
age without a pair of field glasses, which we did not have along that
day. While sitting at lunch in a relatively open place in the for-
est, we observed the top of one of these trees, some 30 meters
high and at least a meter in diameter, against the sky line, and
saw that it was covered with round fruits, some of which we found
on the ground under this tree, and realized that we had found a
very interesting species. Our negro guide felled a somewhat
smaller tree with his machete, and thus enabled us to obtain ex-
cellent fruiting herbarium and museum specimens of the Jamaican
species of Hernandia.
Up to this time the tree does not appear to have been definitely
known to botanists in the island of Jamaica. Patrick Browne
(Civil and Natural History of Jamaica, ^Jl, 1756), admits the
genus and remarks : " This tree is pretty common in Barbadoes
and Mountserat, and grows to a considerable size in those islands ;
but I have not seen any in Jamaica, though I have been credibly
informed that it was frequent in the parish of Portland. The cups
that sustain and partly invelop the nuts are very large, and, as
they move in the wind, keep a whistling noise, which is often
frightful to unwary travellers. The seeds are very oil)-." Browne
cites Jack-in-a-Box as a common name.
In Flora of the British West Indian Islands, page 285, pub-
lished in i860, Grisebach does not attribute the tree to Jamaica at
all, thus indicating that no specimens of it were extant at that
time, but Meissner, in DeCandolle's Prodromus (151 : 263. 1864),
337
338 Britton : Studies of West Indian plants
does credit it to Jamaica, and cites P. Browne, although, as lie
omits an exclamation mark, it is evident that he did not see a
specimen, nor does his herbarium, now at the New York Botan-
ical Garden, contain any Her'nandia from Jamaica ; Meissner re-
fers the record of P. Browne to the species Hcrnandia sonora L.,
native of the Windward Islands and Porto Rico, and perhaps also
of the East Indies.
Hcrnandia sonora is readily distinguishable from the other spe-
cies by its peltate, long-pointed leaves, and the only other West
Indian species known is the Cuban Hcrnandia cubcnsis Griseb.,
which has narrow long-acuminate leaves. Under H. sonora,
Meissner (DC. Prodr. 264) notes a variety gnadelonpensis from
Guadeloupe Island, which has leaves rounded at the apex and
base, or slightly cordate. It is possible but not probable that
this is the same as the Jamaican tree, but the description is insuf-
ficient to make this certain. In any event, the Jamaican tree is
evidently specifically distinct from either H. sonora, or H. cnbensis.
There is a species of Hcrnandia, H. gidancnsis, in French Guiana,
but not much is known of it other than the plate of Aublet, PI.
Guian. //. 32Q, which shows that this must be quite different from
the plant here to be described.
Hernandia jamaicensis Britton & Harris
A tree 30 m. high or less, with spreading and ascending stout
branches, the trunk becoming at least a meter in diameter, the
young twigs more or less flattened and angled. Leaves subcori-
aceous, sometimes 2.5 dm. long ; petioles stout, somewhat shorter
than the blade, but sometimes 1 dm. in length, the blades elliptic
to elliptic-obovate, obtuse at the apex, obtuse or subcuneate at the
base, 3-nerved or faintly 5-nerved, not at all peltate ; inflorescence
as long as the leaves or longer, racemose or racemose-paniculate ;
calyx of the pistillate flowers turbinate, about 5 mm. long, its
margin truncate ; fruiting calyx subglobose, yellow, fleshy, 3—4
cm. long and about as thick as long, its wall about I mm. thick,
its orifice 1.5-2 cm. wide with a slightly raised margin ; drupe
ovoid, nearly 2 cm. long, 1.5 cm. in diameter, rounded at the
base, bluntly pointed, bluntly 8-ribbed and rugose between the ribs.
On wooded hill, at about 400 meters altitude, near Dolphin
Head, Jamaica [Britton 2321, type; Harris 10J12); Woodstock,
Westmoreland, Jamaica (Harris 9835).

2. THE GENUS CASSIPOUREA IN JAMAICA
Cassipourea was proposed by Aublet (Hist. PI. Guian. i: 528)
in 1775 for a tree of French Guiana, his Cassipourea guianensis
being the type of the genus. Svvartz (Prodr. 84) published the
generic name Lcgnotis, including in it two species, L. elliptica
from Jamaica and L. Cassipourea, based on Aublet's Cassipourea
guianensis ; he assigns no reason why his name thus published in
1788 should replace Aublet's Cassipourea of 1775. Poiret (Lam.
Encycl. Suppl. 2: 131) properly adopted the older generic name
and transferred the Legnotis clliptiea of Swartz to it. A number
of additional species from tropical America and Africa have since
been added by several authors, including Cassipourea alba Griseb.
from the island of Dominica. That Cassipourea Aublet and Leg-
notis Swartz are the same genus seems evident from an examina-
tion of specimens.
Cassipourea elliptica (Sw.) Poir. is a shrub or small tree, some-
times reaching 6 meters in height, and grows in Jamaica on rocky
wooded hillsides. Its elliptic long-pointed leaves are as brilliantly
shining as those of any plant known to me, and individuals seen
in contrast to the duller luster of other trees and shrubs stand out
as most striking elements in the landscape. Mr. Harris, Dr. Hol-
lick, and I, while botanizing near Kempshot, at an altitude of
about 500 meters in the parish of St. James, western Jamaica, on
March 23, 1908, had our first opportunity of studying this won-
derfully beautiful plant in the field, and were fortunate enough to
see its bright white flowers with strikingly laciniate petals, and it
was an experience long to be remembered. The lustrous leaves
and pediceled flowers distinguish Cassipourea elliptica from the two
species to be described below. A remarkable feature of an indi-
vidual tree found by us near Kempshot on March 24, 1908, is the
development of the lower branches, which droop ami bear leaves
not more than one half the size of those on the flowering branches
above, the twigs of these drooping branches being very slender
and repeatedly forked. We preserved herbarium specimens of this
curious bud-sport ; if cuttings from such a branch could be prop-
agated, they would doubtless yield a weeping Cassipourea.
340 Britton : Studies of West Indian plants
The distinguishing characters of the three Jamaica species are
indicated by the following key :
Pedicels as long as the calyx or longer; leaves brilliantly shining. I. C. elliptica.
Pedicels much shorter than the calyx, or scarcely at all developed;
leaves dull or faintly shining.
Leaves elliptic-lanceolate, narrowed at the base, the petioles
about as long as the calyx. 2. C. subsessilis.
Leaves ovate, subcordate at the base, petioles only half as long
as the calyx. 3. C. subcordata.
I. Cassipourea elliptica (Sw.) Poiret
On rocky wooded hills, Kempshot and vicinity {Britton 2307
and 24.23; Harris 10330, 10340); collected also in Jamaica
by Swartz and by Purdie.
2. Cassipourea subsessilis sp. nov.
A tree about 6 m. high with slender spreading branches.
Leaves elliptic-lanceolate, 6-9 cm. long, 3.5 cm. wide or less,
acuminate at the apex, narrowed at the base, entire-margined, dull
green on both sides, or faintly shining above, the midvein promi-
nent beneath, the petioles 4-7 mm. long ; flowers solitary in the
axils, nearly or quite sessile ; calyx campanulate, its tube 3 mm.
long, its lobes ovate to ovate-lanceolate, about as long as the tube;
ovary appressed-pubescent ; capsule subfusiform, appressed-pu-
bescent, about 1.3 mm. long, 2.5 mm. in diameter, surmounted by
the persistent appressed-pubescent style.
On wooded hill near Dolphin Head, parish of Hanover, Ja-
maica, at about 400 meters altitude (Britton 2316 ; Harris 10307').
3. Cassipourea subcordata sp. nov.
A tree 4 m. high, the twigs rather stout, the branches as-
cending. Leaves ovate, bright green on both sides but not
strongly shining, 5-7 cm. long, 3.5 cm. wide or less, short-acumi-
nate at the apex, subcordate at the base, the midvein prominent
beneath, the petioles rather stout, 2-3 mm. long ; flowers 1 or 2
together in the axils, very nearly sessile ; calyx tube obconic, 2. 5
mm. long, the lobes ovate, obtusish, about as long as the tube,
petals white, fimbriate.
Along a brook, Troy, Jamaica {Britton 488, type) ; collected
also by Mr. Harris at the same place (no. 0466).

3. THE GENUS TEREBINTHUS P. BR. IX
THE WEST INDIES
The type species of Terebinthus P. Br. is Pistacia Simaruba L.,
commonly known as the West Indian birch. A subsequent name
for the genus is Bitrscra Jacq. but, as shown by Dr. J. N. Rose
(Contr. U. S. Nat. Herb. 10 : 118), this name is unavailable, because
Terebinthus has priority. Seven species are known to me from the
West Indies, two of them here to be described as new ; the Mexi-
can species have been listed by Dr. Rose.
Leaflets broad, ovate, elliptic, or obovate.
Leaflets 3—1 1 , ovate, acuminate or acute.
Leaflets thin ; bark exfoliating in thin layers. I. T. Simaruba.
Leaflets coriaceous ; bark close. 2. T. Hollickii.
Leaflets only I, obovate to elliptic, obtuse. 3. T. simplicifolia.
Leaflets narrow, oblong to lanceolate or oblanceolate.
Leaflets obtuse at the base. 4. T. glattca.
Leaflets acute at the base.
Inflorescence elongated, sometimes as long as the leaves.
Leaflets 5-1 1, linear-oblong to linear-lanceolate. 5- ^ angustata.
Leaflets 3-5, oblong to oblanceolate. 6. T. inaguensis.
Inflorescence short, compact, in fruit not longer than the
petioles ; leaflets 1-3. 7. T. Nashii.

Thomas to Grenada ; Mexico to Colombia and Venezuela.
Most of the Jamaica trees have pubescent twigs and leaf-rach-
ises ; this hairy race is evidently the typical one, based by Linnaeus
on Sloane, pi. 199.
2. Terebinthus Hollickii sp. nov
A tree 6 m. high, with trunk 2.5 dm. in diameter, its bark about
8 mm. thick, reddish-gray outside, red inside, close, not peeling
off in papery layers. Young twigs stout, pubescent ; leaves 8-12
342 Britton : Studies of West Indian plants
cm. long, clustered at the ends of the twigs ; rachis pubescent with
spreading hairs; leaflets 3-7, coriaceous, ovate 3-6 cm. long, 1.5
-3 cm. wide, entire-margined, obliquely rounded at the base, short-
acuminate at the apex, glabrous or very nearly so when old, very
inconspicuously veined above, rather prominently veined beneath ;
petiolules stout, 3-5 mm. long ; fruiting inflorescence 4-7 cm.
long, the raceme simple or slightly compound, its axis pubescent ;
fruits 8-10 mm. long, about 7 mm. thick, bluntly triangular, on
stout pedicels 4 or 5 mm. long ; seed sharply 3-angled.
Dry rocky hillside, Fort Henderson, Kingston Harbor, Ja-
maica (N. L. Britton & Arthur Hollick, March 2, 1908, no. 1816).
3. Terebinthus simplicifolia (DC.)
Bursera simplicifolia DC. Prodr. 2 : 78. 182?.
Frequent on dry hillsides near the southern coast of Jamaica,
becoming at least 13 meters high.

Bahama Islands, from Eleuthera and Great Guana Cay to
Inagua.
Combs 454, from Calicita, Santa Clara Province, Cuba, resem-
bles this very closely, more closely than it does T. angustata.
7. Terebinthus Nashii sp. nov.
A tree about 3 m. high with nearly smooth terete twigs,
glabrous throughout. Leaves I— 3-foliolate, the slender petiole
5—15 mm. long, somewhat glaucous; leaflets linear-oblong, nar-
rowed at the base, obtuse or acutish and mucronulate at the apex,
3—5 cm. long, 1-1.5 cm. wide, pale green, very indistinctly veined
on both sides, chartaceous ; fruiting inflorescence short, few-
fruited, 2 cm. long or less ; fruits 6—j mm. long, nearly as thick
as long, borne on short stalks, 2-5 mm. long, the calyx persistent
at their bases.

Gonaives to La Hotte Rochee on road to Terre Neuve {Geo.
V. Nash & Norman Taylor, August 12, 1905, no. iJSp).
4. PASSIFLORA CILIATA Ait.
This species was described in 1789 (Hort. Kew. I : 310) from
plants cultivated by Mrs. Norman, who introduced it into England
from Jamaica in that year. In the Botanical Magazine, plate 288,
published January 1st, 1795, Curtis remarks that he saw it during
the latter part of the preceding summer with great profusion of
flowers in several collections, and the figure given by him at this
place was made from a plant in the collection of Mr. Vere.
This beautiful passion-flower seems to have been much mis-
understood by subsequent botanists. It appears to be confined
naturally to the island of Jamaica, where Mrs. Britton found it in
March, 1908, in quantities along roadsides through the hills near
Bulstrode, parish of Westmoreland, growing with P. foetida.
The plant has been supposed to be a variety of P. foetida, and
has been so ranked by a number of authors. Grisebach, in Flora
of the British West Indies, however, regarded it as specifically dis-
tinct, but apparently erred in attributing it to the Bahamas as well
as to Jamaica. It has not been found in the Bahamas during any
of our extensive explorations of that archipelago. So far as one
can see, Grisebach was quite justified in maintaining it as a species
distinct from P. foetida.
5. BIDENS PILOSA L.
This species was founded by Linnaeus (Sp. PI. 832) in 1753 on
the " Bidens latifolia hirsutior semine angustiore radiato " of Dil-
lenius Hort. Eltham. 51. pi. 4.3. f.51. The name has since been
used by many authors for a very common and well-known tropical
weed and often with the remark that it is not pilose. Dr. Gray
surmised that the figure of Dillenius might really have been made
from a plant of/?, frondosa. During repeated trips to the West
Indies I have looked closely at a great many individuals of this
weedy plant but never could find any pilose ones until this spring ;
the species is usually almost or quite without trichomes. But at
Moneague, Parish of St. Ann's, Jamaica, in April, 1908, I noticed
344 Britton : Studies of West Indian plants
with great interest a roadside ditch full of these plants, some
densely pilose all over, some essentially glabrous. I could not
see at the time of collecting nor have I been able to see from
further study of the dried specimens, any other difference what-
ever in the two races. Both arc rayless, have identical achenes
varying from 2 to 4, with awns relatively of the same length,
leaves of the same shape and texture and involucral scales alike
From the environment and occurrence there was nothing to pre-
vent one coming from the seeds of the other. The plants as here
observed are not as stout nor as large-leaved as the figure of Dil-
lenius. The typical race of Bidens pilosa L. is then well named,
but it is apparently rare.
Bidens laicantlia (L.) Willd. published by Linnaeus as Coreop-
sis leucantlia (Sp. PI. ed. 2. 1282), also a very common tropical
weed, has sometimes been regarded as a variety of B. pilosa. It
has white rays often 1.5 cm. long, and in life appears very different,
but herbarium specimens from which the rays have fallen are
often difficult to place. It commonly grows with the glabrous B.
pilosa, but perhaps more frequently in separate patches and in the
West Indies one frequently sees large areas inhabited by the one
to the exclusion of the other. At Kempshot, near Montego
Bay, Jamaica, they grew together in a small garden and I was
able to study them side by side ; here B. leucantha had the invo-
lucral scales spreading at flowering time, while those of the glab-
rous B. pilosa were erect. I am inclined to regard 'leucantha as a
distinct species. There is a race with undivided leaves.
6. THE GENUS MALACHE B. VOGEL.
Malaclie scabra was proposed by B. Vogel (Trew, PI. Select.
50. pi. 90. 1772) as the name of a mangrove-swamp shrub
common nearly throughout the West Indian region, subsequently
called by Cavanilles (Diss. 3: 136. pi. 46. f. 1. 1787) Pavonia
spicata, and by Swartz (Fl. Ind. Occ. 2: 121 5. 1800) Pavonia
racenwsa. Trew cites pre-Linnaean names for the plant, and gives
a detailed description and a beautiful illustration of it, especially
referring to Sloane, Hist. Jam. 221. pi. ijp. f. 2 ; Sloane's de-
scription and illustration are unmistakable for the species. Lin-
naeus does not appear to have had any name for it.
Brittox : Studies of West Indian plants 345
Pavonia Cav. has as its type species P. spinifex Cav. After
studying quantities of this and of Malache scabra, both in the field
and in the herbarium, I am confident that they should not be
included in the same genus, inasmuch as they differ too widely in
the floral and fruit-structure and in habit ; only the most artificial
classification can retain them as congeneric.
Malache scabra is a typical shrub of coastal swamps from
Florida southward through the Caribbean region to Central
America, Colombia, Trinidad, and Brazil, and is recorded as grow-
ing as far south as Peru on the western side of South America.
Having seen much of this species along mangrove swamps,
nearly or quite always within the tidal influence at high water, I
was surprised and interested while exploring the high rocky
" Cockpit Country" of Jamaica with Air. William Harris in Sep-
tember, 1907, to find a similar plant on hills in wet woods in the
vicinity of Troy, reaching altitudes of at least 600 meters. Mr.
Harris had collected fruiting specimens of it the year before, and
had noticed its resemblance to the coastal shrub ; Professor Urban
has recently described it from these specimens [Harris P4S7), as
Pavonia racemosa var. troyana (Symb. Ant. 5: 530. 1908). I
obtained additional specimens both in flower and fruit in 1907
{Britton 515) and from field studies made then in comparison with
Malache scabra I am convinced that this "Cockpit Country"
plant is specifically distinct, and to be called Malache troyana ;
it has broader involucral bracts, much broader and differently
shaped carpels, the anther-bearing part of the stamen-column pro-
portionately shorter, and the fruiting peduncles are shorter and
stouter. The plant is tall and slender and sometimes approaches
the form of a small tree up to 4 or 5 meters high.

7. HARRISIA, A NEW GENUS OF CACTACEAE
Night-flowering cacti with slender upright branched cylindric
stems, the branches fluted, with from 8 to 1 1 rounded ribs, sepa-
rated by shallow grooves and bearing areoles at frequent intervals,
each areole with several acicular spines. Flowers borne singly,
at areoles near the ends of the branches, funnelform, large, with a
cylindric scaly but spineless tube as long as the limb or longer ;
buds globose, ovoid or obovoid, densely scaled, the scales bearing
long or short woolly hairs ; sepals pink or greenish, linear-lanceo-
late ; petals white ; stamens shorter than the petals, style some-
what longer than the stamens ; fruit globose to ovoid-globose,
green to yellow, spineless but with deciduous scales, the corolla
withering-persistent ; seeds very numerous, small.
The genus is named in honor of William Harris, Superintendent
of Public Gardens and Plantations of Jamaica, distinguished for his
contributions to the knowledge of the flora of that island. The
descriptions are drawn up mainly from field observations and from
living plants in the collections of the New York Botanical Garden.

Description from N. Y. B. G. no. 261-f, collected at George-
town, Long Island, Bahamas, by N. L. Britton and C. F. Mills-
paugh, in 1907 (no. 6jjy). Named in honor of Hon. Herbert
A. Brook, Registrar of the Bahamas, in recognition of his valuable
aid in our exploration of these islands.
The plant of Florida, of which I do not yet know the buds
or the flowers, more closely resembles this Bahamian species
in its spines and areoles than it does any of the others here de-
scribed. Our living plant, N. Y. B. G. no. icjpoo, was collected
by Prof. P. H. Rolfs on islands east of Malabar and brought to
the Garden by Dr. J. K. Small in 1903. As shown by an her-
barium specimen, prepared by Dr. Small at that time (no. yS), the
fruit of this species is nearly globular, about 5 cm. in diameter,
and apparently smooth or nearly so. We also have an excellent
photograph, taken by Mr. C. L. Pollard on Key Largo ; and Cur-
tiss' N. A. Plants no. g6j, from a locality between the Indian
River and the ocean, is this same species, which is described in
Chapman's Southern Flora, at least in so far as the flower is con-
cerned, under the name Cerens monoclonos, but it is not C. mono-
clonos of De Candolle.
8. Harrisia Taylori sp. no v.
Plant light green, branched above, 1.5-2 m. high, the branches
divaricate-ascending, rather stout, 4 or 5 cm. thick, 9-ribbed, the

2-3 cm. apart; spines 9-12, the longer 3-5 cm. long, ascending;
bud globose-ovoid, short-pointed, its scales with sparse curled
grayish-white wool $—6 mm. long.

Piper umbellatum L. Sp. PI. 30. 1753.
Potomorplie umbelleita Miq. Comm. Phyt. 31. 1838.
Field observations in Jamaica demonstrate that the two supposed
species of Potomorplie are not distinct. The difference of peltate
and non-peltate leaves depended upon by Linnaeus and most sub-
sequent authors who have had occasion to describe these plants,
including M. Casimir de Candolle (in Urban, Symb. Ant. 3 : 208
—211), is worthless, because individual plants bear both kinds of
leaves. I had long suspected this to be the case, and while discussing
the matter with Mr. William Harris on the road from Bath to Cuna
Cuna Gap last September, where specimens of both supposed species
were abundant, he almost immediately detected a plant which bore
peltate leaves at its upper nodes and non-peltate leaves at the lower
ones, and we found a plenty of such specimens afterwards {Britton
3j 13). The relative number of spikes, which also has been supposed
to differentiate the species, I had previously found to be quite incon-
stant, and the character of pubescence used in the descriptions by
M. de Candolle is also inconstant, as evidenced by his proposing a
hairy variety of P. peltata (Joe. cit. 210, as Piper peltatum hirtel-
lum C. DC).
M. de Candolle includes the species in the genus Piper, and
describes them as shrubs up to 4 meters high. As a matter of
fact, the plant is not properly a shrub, its stems being soft, not
Britton : Studies of West Indian plan .r,i;7
.appreciably woody ; his principal character to distinguish Piper from
Peperomia is that Piper consists of shrubs and trees and Peperomia
of herbs ; P. peltata should then be excluded from Piper, and as
it has distinct habital characteristics, differing widely from any true
Pipers or Peperomias, I think it better regarded as a distinct genus
under Miquel's name PotomoipJic. Kunth, and also A. Dietrich,
allowed it in Peperomia.
9. THE GENUS STEGNOSPERMA BENTH.
Stegnosperma was established by Bentham (Bot. Voy. Sulphur
17. pi. 12. 1844) with the single species 6". halimifolium Benth.
from Cape St. Lucas, Lower California. The next year, A. Richard
(Ess. Fl. Cub. 632. 1845) proposed an additional species, S.
cnbense A. Rich, from Cuba. Moquin (in DC. Prodr. 132 : 36.
1849) makes no mention of the Cuban plant, though recording it
from Guatemala, but in Bentham and Hooker (Genera Plantarum
3 : 86. 1880) the two supposed species are regarded as one, and
its range extended to Santo Domingo.
The range is now extended to Jamaica, where the plant was
found by us in the Healthshire Hills, an exceedingly dry region
at about 100 meters elevation, south of Spanish Town {Britton &
Harris 10322 ; Britton 3062) ; here it is a woody vine 8 m. long,
climbing to the tops of low trees ; its reddish fleshy fruits are 3-
grooved, borne in short terminal racemes. The Mexican and
Central American plant seems to me to be specifically identical
with that of the West Indies, as maintained by Bentham and also
bv Heimerl in " Die natiirlichen Pflanzenfamilien."
10. UNDESCRIBED SPECIES FROM JAMAICA

Jamaica, Sept. 2 2, 1908 {Britton j 73 7, type; Harris & Britton
10607). An interesting addition to the West Indian peltate-
leaved Dorstenias, three being known from Cuba and one from
Santo Domingo.

nate at the apex, the larger ones 10-16 cm. long, 4-7.5 cm.
wide ; petioles 5-8 mm. long ; fruiting panicles 1 5 cm. long or
less, its branches finely appressed-pubescent ; fruiting pedicels

11. ADDITIONS TO THE LIST OF JAMAICA SEDGES
In 1907 I contributed an enumeration of the sedges of Jamaica
to the Bulletin of the Jamaica Department of Agriculture (5 :
Supplement 1). Further exploration of that island in the autumn
of 1907 and in the spring and autumn of 1908 has disclosed the
occurrence of some additional species and the habitat of others
which were recorded by me from the statements of other botanists.

In my paper in the Jamaica Bulletin, I followed Mr. C. B.
Clarke, in Urban, Symb. Ant. 2 : 44, in recording the continental
North American Cyperus tctragonus Ell. from Jamaica, and in re-
ferring C. anceps to it as a synonym, but abundant material now
convinces me that the species are distinct. This sedge is plentiful
on grassy hillsides and banks in the parish of Manchester [Britton
1024, 3 161); also at Woodstock near Newmarket, in Westmore-
land [Britton 1367). Distribution : Cuba.

12. THE WEST INDIAN SPECIES OF COMOCLADIA P. Br.
Comocladia* P. Br.; L. Syst. eel. 10, 861. 1759
Type species: Comocladia pinnatifida L.
1. Leaves entire or undulate.
A. Glabrous species.
a. Lateral leaflets distinctly stalked.
i. Comocladia pixxatifida L. Syst. ed. 10, 861. 1759
Comocladia integrifolia Jacq. Enum. PI. Carib. 12. 1760.
Type locality: Jamaica.
Both names are based wholly on P. Browne, Hist. Jam. 124,
where the generic name is printed Comocladia. Browne refers
to Sloane's description and figure of "Primus racemosa, caudice
non ramosa" (Hist. Jam. 2: 131. pi. 222. f. 1); the illustration
there given is not wholly satisfactory for the plant which has been
taken for this species, but which is here accepted as usually
interpreted.
Distributiox: Moist woodlands at middle and lower eleva-
tions throughout Jamaica; Haiti and Santo Domingo.
*The spelling of the generic name was changed by Linnaeus t.i ( 'atnoi ladia, but
this form is here regarded as a typographical error, although it was continued by
Linnaeus, in the second edition of Species Plantarum, and in suco litions of
the Systema, but was changed back to the original by Gmi t. ed. [3. 1
The original spelling was accepted by Jacquin, by Swartz. and by most subsequent
authors.

ovate, long-stalked, and with only 3 or 4 teeth on each margin.
The number of teeth is often 9 on each margin. The species
consists of a number of races, differing in width of leaflets, length
of petiolules and number of teeth on the leaf-margins, the
extremes appearing quite different from each other.
A. Richard (in Sagra, Hist. Cub. 10: 155. 1850) remarks

as follows concerning this species, which was subsequently de-
scribed by Grisebach :
"I have observed an example of this tree, but without flowers,
which, it seems to me, could form, if not a distinct species, which
I am not far from believing, at least a very notable variety. The
leaflets are almost as large as the leaves of the 'castafio,' are also
rough on both faces, dentate and spine-like in their contour; and,
in short, recall in all their shape the leaflets of Comocladia dentata,
but are much larger and rougher. If the opportunity comes to see
this plant with flower and fruit it will perhaps be possible to form
a distinct species to which the name Comocladia platyphila* will
apply perfectly."
13. Comocladia intermedia C. Wright; Engler in DC.

Leaves oblong. 3. B. oblongata.
Leaves ovate, oval or ovate-lanceolate, 2.5-9 cm. long.
Leaves bluntly acuminate, or bluntly acute at the apex.

Badiera domingensis DC. Prodr. 1: 335. 1824.
Mountains of Haiti and Santo Domingo. This plant is rep-
resented in the herbarium of the New York Botanical Garden by
the following specimens: "In montibus, Hispaniola (Jacquemont) ;
Sierra del Palo Quemado, Santo Domingo, at 500 meters (Eggers
18 gf); pineland, Marmelade, Haiti, at 900 to 1100 meters {Nash
jig; Nash & Taylor 13 12).
Professor Chodat ignores Badiera Penaea in his monograph,
and describes Eggers no. iSgy as Poly gala domingensis , not recog-
nizing the genus Badiera. Mr. Nash's no. Jig, which is in young
fruit, so closely resembles the original figure of Poly gala Penaea
L. (Plumier, ed. Burmann, pi. 214. f. 1) that it appears to me
the two supposed species must be one; the character cited by
De Candolle (Prodr. 1: 335) of flowers solitary in B. Penaea
and flowers racemose in B. domingensis is doubtful; the Plumier
figure shows the plant in fruit, and in this as in other species of the
genus often only one flower of the cluster produces fruit.
2. Badiera virgata sp. nov.
A shrub or small tree up to 4 meters high, the branches nearly
erect, densely leafy, the twigs finely puberulent. Leaves obovate,
or obovate-oblanceolate, rigid, 10 mm. long or less, 4-8 mm. wide,
puberulent or minutely papillose-puberulent, or becoming nearly
or quite glabrous when old, rounded at the apex, or some of them
slightly emarginate, narrowed at the base, the petioles pubescent,
1— 1 .5 mm. long, the midvein slightly elevated beneath, the lateral
venation wholly obscure; flowers several in the axillary clusters
or solitary, yellow-green, 2 mm. long; fruiting pedicels 1.5 mm.
long; fruit 5 mm. long, the lobes narrowly winged (only imperfect
ones with one lobe developed seen).

Thickets in dry soil, Oriente, Camagiiey, and Santa Clara,
Cuba. (Type, Britton 2086, from United States Naval Station,
Guantanamo Bay, March 17-30, 1909.)
3. Badiera oblongata N. L. Britton, Bull. N. Y. Bot.
Gard. 5: 314. 1907
Distribution: Bahama Islands: Andros, New Providence, Cat
Island, Acklin's Island, Crooked Island, Watling's Island, Caicos
Islands; Cayo Sabinal and mainland of Camagiiey, Cuba {Shafer
878 1085, 977; also collected in Cuba by Wright, no. 115 in part).
The Cuban specimens here referred have leaves mostly more
obtuse at the base than those of the typical Bahamian plant, but
a specimen from Andros Island {Small & Carter 8681) seems to
be identical with them.
A plant from the palm barren at Santa Clara, Cuba {Britton
& Wilson 6066), has shorter emarginate leaves 12-20 mm. long,
with the midvein deeply impressed above; it is tentatively re-
ferred to this species.

districts from sea level up to 1100 meters elevation.
5. Badiera cubensis sp. now
Polygala diversifolia Chodat, Mem. Soc. Phys. Geneve 312:
10. 1893. Not L.
Leaves ovate to elliptic, 2.5-6 cm. long, 1.5-3.5 cm- wide,
bluntly acuminate or acute at the apex, cuneate-narrowed or
acute at the base; fruit 7.5-8.5 mm. long, 10 mm. wide, lobed to
about one third, the lobes rounded.
Cuban woodlands; type, Wright, no. 191 3 from "La loma
pelada, Dec. 27," in herb. N. Y. Bot. Gard.; also collected by
Wright at "La Sabanilla" and distributed under this same number;
Wright's no. 3496 belongs to this species, and also part of his 115,
collected in eastern Cuba.
Brittox : Studies of West Indian plants 363
Professor Chodat indicates this Cuban species as occurring
also in Jamaica, but this I take to be an error.
6. Badiera montana sp. nor.
A shrub, 3 m. high, the twigs densely puberulent. Leaves
broadly oval, 4-5 cm. long, 2.5-3.5 cm- wide, firm in texture,
quite densely puberulent when unfolding and sparingly puberulent
when mature, rounded or slightly emarginate at the apex, acutish
at the base, dull dark green, the midvein slightly impressed in the
upper surface, elevated on the underside, the lateral veins few,
slender, the rather stout puberulent petioles 2-3 mm. long; in-
florescence several-flowered; bracts ovate, acute, pubescent,
about 0.5 mm. long; fruiting pedicels pubescent, 1.5-2 mm. long;
stipe of the fruit 1 mm. long; fruit 8-10 mm. long, 10-12 mm. wide
at the top, puberulent, lobed to about one fifth, the lobes rounded-
truncate.
Rocky wooded hill, Arroyo Grande, Trinidad Mountains, Cuba,
at about 700 meters altitude (Britton & Wilson 5461, March 11,
12, 1910).
Differs from B. cubensis by its obtuse leaves, larger and longer
fruit.
7. Badiera Berteriana Spreng. Syst. 3: 172. 1826
Described as with oblong-lanceolate obtuse leaves and re-
corded as from Hispaniola. Professor Chodat does not refer to
this species in his monograph; it was collected by Bertero and
called by him Polygala domingensis, but Sprengel's description
indicates that it is not Polygala domingensis of Jacquin, here
referred to Badiera Penaea (L.) DC.
Excluded Species.
Badiera (?) acuminata (Willd.) DC. Prodr. 1: 335 is Polvoala
acuminata Willd. Sp. PI. 3: 887, native of Peru and Chile.
Professor Chodat describes it as new in his monograph (p. 46),
but the name dates from at least the year 1805.
Badiera (?) divaricata DC. Prodr. 1: 335, from Para, South
America (presumably Brazil), was not taken up by Mr. A. \Y.
Bennett in the Flora Brasiliensis.

16. DENDROPANAX IN THE WEST INDIES
1. Dendropanax arboreum (L.) Dene. & Planch.
A tree, up to 20 m. high, but usually much smaller and often
flowering as a shrub. Leaves chartaceous, from ovate to obovate,
mostly acuminate at the apex, narrowed or rounded at the base,
often 2 dm. long; inflorescence from shorter than the leaves to
equaling them, or longer, the 20 umbels or fewer racemosely
arranged and umbellate at the summit, sometimes leafy-bracted,
but the bracts usually small, ovate to lanceolate; peduncles of
the umbels slender, ascending, up to 3 cm. long in fruit; pedicels
1 3^ to 3 times as long as the flowers, somewhat elongating in
fruit; petals white or greenish ; calyx rather sharply toothed, about
2 mm. wide at flowering time; fruit black, strongly lobed, 6-8 mm.
thick.
Widely distributed at lower and middle altitudes in moist
or wet districts in Jamaica, Cuba, Hispaniola, Porto Rico, and
on Signal Hill, St. Thomas. Ascends to 1,600 meters in Jamaica.
2. Dendropanax samydifolium (C. Wright) Seem.
This species is known to me only from the original specimens
collected by Wright at S. Felepina near La Grifa, western Cuba;
Wright's description calls for a tree up to 13 meters high. The
leaf base is decurrent on the petiole. The species seems very
closely related to D. arboreum, which is abundant in the mountains
and hills of western Cuba.

3. Dendropanax brachypodum (Urban) Britton nom. nov.
Gilibertia brachypoda Urban, Symb. Ant. 5: 452. 1908.
A short-pctioled and long-pediceled Haitian mountain species,
related to D. arboreum, known to me only from Professor Urban's
description.
4. Dendropanax laurifolium (E. March.) R. C. Schneider
A detailed description of this endemic Porto Rico mountain
tree is published by Professor Urban in Symbolae Antillanae 1 :
203.
5. Dendropanax cuneifolium (C. Wright) Seem.
A shrub or tree up to 6 m. high, the branches slender, often
drooping. Leaves spatulate to oblong-oblanceolate, 2 dm. long
or less, 1.5-6 cm. wide, obtuse, or bluntly acute at the apex,
cuneate at the base, the petiole 1/6 to 1/4 the length of the blade;
peduncle slender, straight, as long as the leaves or longer; umbel
7-20-flowered ; pedicels 1.5-2 cm. long; petals green, acute; flower-
ing calyx about 4 mm. broad; fruit globose to globose-oblong,
black, 6-8 mm. thick, the persistent style about half its length.
Banks of streams and wooded bogs at lower and middle eleva-
tions, Pinar del Rio and Isle of Pines, Cuba.
6. Dendropanax nutans (Sw.) Dene. & Planch.
A shrub with stout gray branches. Leaves ovate to ovate-
elliptic, coriaceous, 10 cm. long or less, acute or short-acuminate at
the apex, narrowed or rounded at the base, the veins rather
prominent on the under side, the stout petioles very unequal in
length, sometimes two thirds as long as the blade; peduncle
stout, 5-7 cm. long, bracted at or near the base; umbels many-
flowered, inclined or nodding; pedicels 2-3 cm. long; flowering
calyx 5 mm. broad.
Known only from Blue Mountain Peak, Jamaica, where it is
reported as abundant. Professor Urban (Symb. Ant. 1 : 200)
characterizes the umbel as strictly erect, but it is inclined or
nodding in all specimens seen by me.
7. Dendropanax pendulum (Sw.) Dene. & Planch.
A shrub about 4 m. high. Leaves chartaceous in texture,
ovate, acute or bluntish at the apex, rounded or subcordate at
the base, triplinerved and rather prominently pinnately veined,
Brittox : Studies of West Indian plants
the blades 12 cm. long or less, nearly twice as long as wide;
petioles rather stout, one half to two thirds as long as the blades;
peduncle much longer than the leaves, pendulous, 2 dm. long or
less, bracted and jointed a little below the middle; umbel many-
flowered; pedicels slender, 15-18 mm. long; flowering calyx
broadly turbinate, 3.5 mm. broad; petals oblong-lanceolate, about
as long as the calyx.
Cockpit Country, Jamaica, Harris Q188, from Lapland, near
Catadupa; this specimen agrees with the type specimen of Hedera
nutans Sw., in the herbarium of the British Museum of Natural
History. The species is also recorded by Marchand from Catha-
rine's Peak, collected by Eggers, 3651, which I have not seen.
8. Dendropanax grandiflorum sp. now
A tree, about 8 m. high. Leaves chartaceous, obovate, 5-10
cm. long, 5 cm. wide or less, bluntly pointed at the apex, cuneate-
narrowed at the base, rather strongly pinnately veined, the margins
slightly revolute, the stout petioles about I cm. long or less;
inflorescence of simple, terminal, few-flowered umbels, or rarely
a secondary umbel borne halfway up on the peduncle; peduncle
rather stout, 3-5 cm. long, bracted and jointed just above the
base; flowers 8 or fewer in the umbels; pedicels rather stout,
nearly erect, 1.5-2 cm. long; flowering calyx 8 mm. high, narrowly
campanulate, its mouth 6-7 mm. broad; corolla 5 mm. long just
before expanding, the bud rounded; anthers in the unopen bud
about as long as the filaments; fruit oblong, I cm. long, 7 mm.
thick, the persistent style 6-7 mm. long.
Peckham woods, Upper Clarendon, Jamaica, July 7, 191 1,
Harris 10QQ4.
9. Dendropanax elongatum sp. nov.
A slender tree about 8 m. high. Leaves clustered at the ends
of the branches, oblong to oblong-lanceolate, coriaceous, faintly
pinnately veined, acute at the apex, narrowed or somewhat rounded
at the base, the blade 15 cm. long or less; the petiole one sixth
to one third as long as the blade; peduncle shorter than the
larger leaves, 8-12 cm. long, bracted somewhat below the middle,
the bracts triangular-ovate, apparently nearly erect; very young
inflorescence depressed-hemispheric, 8 mm. broad ; the flower buds
sessile or nearly so.
Peckham woods, Upper Clarendon, Jamaica, at 800 to 900
meters elevation, January 3, 1910, Harris 108/4.
1 Britton : Studies of West Indian plants
The very young slate of the inflorescence does not enable me
to give a description of the flowers of this interesting tree, and its
generic position is therefore uncertain. Its jointed and bracted
peduncle is similar to that of Dendropanax pendulum, but its
foliage is altogether different from that species.
10. Dendropanax grande sp. nov.
A tree up to 16 m. high. Leaves clustered at the ends of the
branches, ovate to ovate-elliptic, coriaceous in texture, rather
prominently pinnately veined, obtuse at both ends, the blade 15
cm. long or less, the stout petioles as long as the blades, or shorter;
peduncle much shorter than the leaves, erect, stout, about 4 cm.
long, bracted at the base; pedicels numerous, about 50, rather
stout, 2 cm. long; flowering calyx subhemispheric, 5 mm. broad;
petals lanceolate, about as long as the calyx; filaments rather
stout, somewhat longer than the petals.
Moneague, Jamaica, Alexander Prior, May 1850.
11. Dendropanax blakeanum sp. nov.

tion, Harris & Britton 10761, collected March 10, 1909.
Differs from Dendropanax nutans in the longer, strictly erect,
few-flowered peduncles, and in the venation, texture, and shape
of the leaves.

branches, chartaceous in texture, broadly ovate, prominently pin-
nately veined, obtuse, or short-acuminate at the apex, cordate, or
subcordate at the base, the blades 2 dm. long or less, about two
thirds as wide as long, the stout petioles about one half as long as

17. THE GENUS CAMERARIA (PLUMIER) L.
The genus was accepted by Linnaeus from Plumier, C. latifolia
being the type species, and C. angustifolia L. also appearing in the
original publication of the genus, which is wholly West Indian in
distribution, so far as I am aware.
1. Cameraria latifolia L. Sp. PI. 210. 1753
This is a shrub or tree up to 15 m. high, as observed by me at
the United States Naval Station, Guantanamo Bay, Cuba. It has
characteristic ovate-elliptic acuminate leaves. Its fruit is about
6 cm. long. The species seems to be widely distributed in Cuba;
occurring in the provinces of Oriente, Matanzas, and Havana.
In Jamaica it is apparently rare, the only specimen seen by me
being one collected by Dr. A. Hollick and myself {2045) in rocky
woods at Negril, the extreme western end of that island. It is
recorded from Haiti but I have seen no specimens from Hispaniola,
which is presumably the type locality.
2. Cameraria angustifolia L. Sp. PI. 210. 1753
My knowledge of this species rests wholly on Plumier's descrip-
tion and plate 72, figure 2, where it is illustrated as having linear-
acuminate leaves and fruit 2.5 cm. long. According to Miller,
cited by Grisebach, Fl. Br. W. I. 410, it was found in Jamaica,
but it is unknown to us from that, island.
3. Cameraria retusa Griseb. Fl. Br. W. I. 410. 1861
(C. angustifolia Griseb. loc. cit. not L.)
This is wholly a Cuban species, so far as it is represented in
our collections, occurring in the provinces of Santa Clara, Havana,
6 Bkitton : Studies of West Indian plants
Pinar del Rio, and on the Isle of Pines. It has lanceolate to
oblong leaves, which are obtuse and emarginate at the apex. Its
fruit is about 2 cm. long, the narrowly linear terminal wing about
as long as the ovoid body. Its flowers are only about I cm. long,
the corolla limb about 1.5 cm. wide.
I take as the type of this species the specimen from "West
Indies," collected by Lane, and preserved in the Kew Herbarium.
4. Cameraria oblongifolia sp. nov.
A tree 4-6 m. high with slender twigs. Leaves oblong to
oblong-lanceolate, acutish to obtuse or minutely emarginate at
the apex, narrowed at the base, 2-3.5 cm- long, 14 mm. wide or
less, the slender petiole about 2 mm. long; corolla about 17 mm.
broad; fruit compressed, lanceolate, 2-3 cm. long, about I cm.
wide, grooved at the base on one side, the terminal wing oblong-
triangular, obtuse, about as long as the body.
In wet woods near Tiffin, Camagiiey, November 1-5, 1909,
Shafer 2877; also represented by part of Wright's Cuban no.
2Q50, collected at Hanabana.
The other part of Wright's 2950, which has ovate-lanceolate
acuminate leaves, may represent another species. It has much
more slender and longer petioles than C. oblongifolia, but the speci-
mens examined by me are too imperfect to afford a complete
description. Combs' no. ig, collected in Cieneguita in the
province of Santa Clara, appears to be the same as this, but our
specimen of that number also is incomplete.
5. Cameraria microphylla sp. nov.
A tree up to 5 m. high, intricately branched, the twigs very
slender. Leaves oblong 10 oblong-obovate, I cm. long or less,
2-4 mm. wide, emarginate at the apex, narrowed at the base, the
margins strongly revolute; fruit 2 cm. long, 4-6 mm. wide, com-
pressed, the wing oblique, sinuate, terminal and lateral, similar
to that of C. Jatifolia but very much smaller.
Near the northwestern end of Cayo Coco, Camagiiey, October
23-24, 1909, Shafer 270Q.

20. NOTES ON SPECIES OF SOLANUM
Solanum Blodgettii Chapm.
This species is cited by Mr. O. E. Schulz* as a synonym of
Solanum bahamense subarmatum (Willd.) O. E. Schulz, but he has
wholly misunderstood its type specimens, which show that it
is more nearly related to S. verbascifolium than to S. bahamense;
it grows plentifully on Key West, Florida (Blodgett, type; Merrill;
Pollard, Collins & Morris 3; Britton 320; Lansing 1969s), in the
Florida Everglades (Britton 237; Small & Wilson 1678, 1962;
Small & Carter 2674, 2673, 2936, 3101), and is to be added to the
West Indian Flora, as it occurs on Cat Cay, Bahamas (Millspaugh
2341; Brace 3749).
The varietal name Solanum bahamense subarmatum, under which
Mr. Schulz groups nearly or quite unarmed specimens of S.
bahamense, is redundant, for there is every transition from very
prickly plants to entirely unarmed ones throughout the range
of the species, individual bushes often bearing prickles below
and being quite devoid of them above. Harris 8169, from
Plowden Hill, Jamaica, as represented by our specimen, is un-
armed, though the duplicate of it, examined by Mr. Schulz, is
referred by him to the typical prickly form.
Solanum boldoense A. DC.
This interesting Cuban vine is apparently of quite local
distribution at widely separated stations; about Matanzas it
* Urban, Symb. Ant. 6: 223.
12 Britton : Studies of West Indian plants
grows especially in the famous gorge of the Yumury or Yumuri
River (Rugel 145). Mr. Schulz (loc. cit. 170) erroneously spells
this "Tomory," while Mr. A. H. Moore* also has it wrong as
"Sumuri." This gorge is one of the scenic attractions of the
northern coast of Cuba; the handwriting of Rugel's labels is
somewhat difficult to decipher. In Pinar del Rio it inhabits
limestone rocks at San Diego de los Banos {Britton, Earle &
Gager 6674); C. Wright's specimen 381 was collected in Oriente;
the locality of the type specimen is doubtfully cited as Havana.
21. NOTES ON TWO JAMAICA PLANTS
Ampelocissus Alexandri Urban, Symb. Ant. 6: 15. 1909
To the description may be added "berry depressed-globose,
black, shining, 1.5 cm. in diameter, the pulp watery; seeds 2 or 3,
depressed-obovoid, slightly rugose, rather deeply and broadly
grooved, 5 mm. long, 4 mm. wide."
Wooded hillside, Union Hill near Moneague, St. Ann's,
Jamaica, at 500 meters altitude, Britton & Rollick 2767; this
station is within a few miles of the type locality at Mount Diablo.
Tabernaemontana discolor Sw. Prodr. 52. 1788
Tabemaemontana ochroleuca Urban, Symb. Ant. 6: 34. 1909.
An examination of the type specimen of Swartz' species in
the herbarium of the British Museum of Natural History estab-
lishes the identity of these species.
22. THE GENUS GINORIA IN CUBA
GlNORIA AMERICANA Jacq.
As intimated by Koehne (Bot. Jahrb. 3: 349) this species
may sometimes bear spines, as observed by me on plants in the
palm barren at Santa Clara, in March, 1910 (Britton & Wilson
60Q3). This shrub grows along brooks and streams, attaining a
height of 2.5 meters, at lower elevations in all provinces of Cuba,
ascending to 160 meters in Oriente.
* Proc. Am. Acad. 42: 530.
Britton : Studies of West Indian plants 13
Ginoria spinosa Griseb. Cat. PI. Cub. 106. 1866
I know this only from Wright's 2545, collected in eastern
Cuba (not western Cuba, as cited by Koehne). Rugel's 727 from
the Rio San Juan at Matanzas, as shown by our specimen, is
certainly G. americana Jacq. and was so written up by Grisebach,
though this number, as studied by Koehne, is by him referred to G.
spinosa. The true G. spinosa Griseb. {Wright 2545) is quite a
different plant, with much smaller leaves and acicular spines; it
is possible, however, that the species are not distinct.
Ginoria glabra Griseb. Cat. PI. Cub. 106. 1866
Known to me from Wright's 2544, collected in eastern Cuba;
and from Shafer's 8784, collected at Farallon de la Perla, Oriente,
where it grows on cliffs as a shrub 6 dm. high. It is evidently
quite distinct from the other species.
Ginoria arborea sp. nov.
A tree, 8 meters high, the trunk up to 2.5 dm. thick, the
bark gray, the branching irregular, the twigs of the season 4-
angled with internodes 5-15 mm. apart; nodal spines 4, spread-
ing, recurved, yellowish, I— 1.5 mm. long. Leaves sessile, linear-
oblong, 1.5-3 cm- l°ng> 2~5 mm- wide, coriaceous, bright green,
shining, obtuse at the apex, narrowed at the base, strongly pin-
nately veined, the veins prominent on both surfaces; flowers
solitary in the axils; pedicels filiform, a little shorter than the
leaves; sepals triangular-lanceolate, acute, 4 mm. long.
Thicket, Leeward Point, United States Naval Station, Guanta-
namo Bay, Cuba, March 1909, Britton 2217.
Ginoria curvispina Koehne, loc. cit. 349. 1882
In the palm barren near Santayana, Camagiiey, this species
is a shrub I meter high {Britton 2368) ; near Tiffin, Camagiiey,
it grows in wet woods and becomes nearly 3 meters high.

I. COMOCLADIA PINNATIFOLIA L. Syst. ed. 10, 86l. 1 759
Professor Urban has pointed out. to me that Linnaeus, who
printed the speeific name pinnatif., more likely intended this con-
traction to mean pinnatif olia than pinnatifida, as I printed it,
following the Kew Index.
12. COMOCLADIA PLATYPHYLLA A. Rich.
The species ranges westward in Cuba into the province of Pinar
del Rio as far as Corrientes Bay {Britton ef Cornell 9914).
14. Comocladia cuneata nom. nov.
Comocladia acuminata Britton, Bull. Torrey Club 37: 349. 1910.
Not C. acuminata Moc. & Sesse; DC. Prodr. 2: 65. 1825.
Known hitherto only from the type specimen, this species has
recently been collected by Rose, Fitch and Russell {4185) at San
Pedro de Macoris, Santo Domingo. The broadly cuneate leaf-
bases distinguish it from its relatives.
15. Comocladia glabra Spreng.
In Flora Portoricensis, Professor Urban refers to this species,
the C. acuminata Moc. & Sesse, as a variety, and states that it is
Porto Rican, rather than Mexican as supposed by DeCandolle.

33. A HYBRID PALM
On the sterile "savannas" north and east of Camaguey, Cuba,
palms of two species of Copernicia abound. The one, C. Jwspita,
has grey-green, thin foliage with spiny- toothed petioles about as
long as the blades, and elongated, slender panicles; the other, C.
macroglossa, has bright green, rigid foliage with very short, broad,
unarmed petioles, the blades spiny-toothed on the margins of the
outermost segments and on the upper surface of the ribs of the
undivided part, the stout panicles not much longer than the
leaves and the inflorescence with large bracts.
Of the two, C. hospita is the more abundant, C. macroglossa
growing in colonies, more or less surrounded by it. At many
places where the two grow together, plants intermediate in foliage
characters occur, their leaves with spiny-toothed petioles of various
lengths, the blades with sparingly spiny-toothed margins, other-
wise smooth, and in color varying from green to grey, the panicles
short and the inflorescence lacking the characteristic large bracts
of C. macroglossa.
Field observations during four days with Mr. John F. Cowell,
led us to the conclusion that these intermediate plants are of
hybrid origin rather than a third species, as was first suggested.

all respects. I have not seen the type specimen. The shrub is
abundant in the limestone hills of Pinar del Rio.

36. ADDITIONAL SPECIES OF TABEBUIA Gomez
The type species is Bignonia Tabebuya Veil., of Brazil, a
species with simple leaves. It is not possible to separate the
group into two genera, the one with simple, the other with com-
pound leaves, as has been proposed by several authors,* calling
the compound-leaved species Tecomas, and the true type of
Tecoma Juss. is Bignonia stans L. {Tecoma stans HBK., Steno-
lobinm stans Seem.). The two-lipped calyx of the type species of
Tabebuia is not constant through the group.
Tabebuia Brooksiana sp. nov.
A tree, up to 30 m. high. Leaves 4-7-foliolate; petioles 12 cm.
long or less; petioles slender, 1-4 cm. long; leaflets oblong, oblong-
lanceolate or oblong-oblanceolate, chartaceous, 5-12 cm. long, 4
cm. wide or less, faintly shining above with the veins impressed,
dull, mostly finely reticulate-veined when mature, and lepidote
beneath, with the midvein and lateral veins prominent, obtuse,
acute or retuse at the apex, the base obtuse or acutish; flowers
clustered; calyx 2-lipped, 10-15 mm- long; corolla pink, 5-6 cm.
long, the tube about 5 mm. long, the narrowly campanulate
throat about 3.5 cm. long, the limb about 1.5 cm. long, its un-
dulate lobes ciliolate.
Woodlands, provinces of Oriente and Camaguey, Cuba, from
sea-level up to 350 m. altitude. Type from Ensenada de Mora,
Oriente {Britton, Cowell & Shafer 12985). Referred by Grisebach
to Tecoma Leacoxylon Mart, and to T. Leucoxylon reticularis
Griseb. The species is named in honor of Mr. Theodore Brooks
of Guantanamo, who has rendered important aid to scientific
exploration. Tecoma heptaphylla A. Rich, in Sagra, Hist. Cub.
11: 106 (not Martius), described as with 7-foliolate leaves from
Vuelta de Abajo (Pinar del Rio), Cuba, is not known to me; I
have seen no species with 7-foliolate leaves from western Cuba.
Tabebuia Shaferi sp. nov.
A tree, up to 10 m. high. Larger leaves 6-8-foliolate ; petioles
3-4 cm. long; petiolules 2 cm. long or less; leaflets ovate-oblong to
suborbicular, chartaceous, the larger 6 cm. long, 3-5 cm. wide,
dark green above, paler beneath, minutely and densely reticulated

the apex rounded or obtuse, the base subcordate; "flowers
pinkish"; capsule 12 cm. long; seeds 5 mm. long, 7 mm. wide, the
wings 5 mm. wide.

Tabebuia pachyphylla sp. now
A tree, up to 12 m. high. Petioles stout, 6-8 cm. long; petiololes
stout, 4 cm. long or less; leaflets 5-7, oblong to ovate-oblong,
coriaceous, 5-12 cm. long, 2.5-6 cm. wide, lustrous above, dull
and densely minutely reticulate-veined beneath, the midvein
prominent, the lateral veins slender, the apex bluntly acute, the
base rounded or subcordate; flowers pink, clustered; calyx 15 mm.
long, bluntly lobed; corolla pink, glabrous, about 5 cm. long, its
narrow throat about twice as long as the limb, its lobes rounded.
Mountains of northeastern Cuba. Type specimen collected
at Arroyo del Medio, Sierra Nipe, Oriente, Cuba, 450-550 m.
alt. (Shafer 364s).
Tabebuia trinitensis sp. nov.
A tree up to 10 m. high. Leaves 4-foliolate or 5-foliolate;
petioles slender, 8-1 1 cm. long; petiolules slender, 4 cm. long or less;

above, paler and lepidote beneath, the larger ones 11-15 cm. long,
3-4 cm. wide, bluntly acute or acuminate at the apex, obtuse at
the base, finely reticulate-veined and the primary venation rather
prominent on both sides.
Hanabanilla Falls, Trinidad Mountains, province of Santa
Clara, Cuba (Britton, Earle &■ Wilson 4866).
The description is from leaf-specimens only but these indicate
that the tree is a species distinct from all others of Cuba. The
ultimate venation and texture of the leaflets differentiate it from
T. Brooksiana Britton.
Tabebuia calcicola sp. nov.
A slender tree, up to 6 m. high. Leaves 2-5-foliolate; petioles
stout, lepidote, 4-5 cm. long; petiolules lepidote, 1.5 cm. long or
less; leaflets coriaceous, light green, ovate to ovate-oblong, 3.5-8

FURTHER STUDIES OF BADIERA DC.
Since the publication of my former paper on this genus (Bull.
Torrey Club 37: 360-363. 1910), additional specimens which
have come to hand afford the following notes and descriptions.
1. Badiera Penaea (L.) DC.
Professor Urban has informed me that my opinion that this
is identical with Badiera domingensis (Jacq.) DC. is correct,
although he has distributed Santo Domingo specimens under the
name B. domingensis.
la. Badiera portoricensis sp. nov.
A tree up to 6 m. high, the trunk sometimes 1.5 m. in diameter,
the slender branches ascending, the young twigs appressed-
pubescent. Leaves subcoriaceous, obovate, 3 cm. long or less,
7-15 mm. wide, bright green and shining above, paler and rather
dull green beneath, both surfaces with short, scattered hairs when
young, becoming glabrate above, the midvein slightly impressed
above, rather prominent beneath, the lateral veins few, distant,
obscure, the apex rounded or obtuse, the base narrowed or cuneate,
the pubescent petioles 1-2.5 mm. long; inflorescence few-several-
flowered, 4-6 mm. long; bracts ovate or ovate-lanceolate, acute,
pubescent, 0.5 mm. long; pedicels appressed-pubescent, 1.5-2.5
mm. long; sepals broadly ovate, obtuse, ciliolate, the larger about
1 mm. long; petals white; keel appressed-pubescent, 2 mm. long,
narrowed below; fruit about 6 mm. wide, about 5 mm. high,
finely pubescent, narrowly margined, notched at the apex, sub-
truncate at the base, its stipe about 0.6 mm. long.
Rocky slopes and hillsides, western Porto Rico, especially
on serpentine, from sea-level to 700 m. altitude. Type collected
at Guanajibo, near Mayaguez (Britton, Cornell & Brown 4349).
Recorded by Bello from my type locality as B. domingensis DC.
[Polygala domingensis Jacq.; B. Penaea (L.) DC] of Hispaniola,
to which species it is nearest related, but which differs in pilose-
pubescent twigs, rather densely pubescent leaves, and much more
pubescent, shorter-pedicelled flowers.
Britton: Studies of West Indian plants 495
2. Badiera virgata Britton
The specimen referred to by me under B. oblongata Britton
{Britton & Wilson 6066) from Santa Clara, Cuba, is now, in the
light of additional material, put with B. virgata, as a broad-leaved
race.
4. Badiera diversifolia (L.) DC.
This, the only Jamaican species of the genus, forms a tree
up to 6 m. high, as at St. Ann's Bay {Britton 24Q8).
5. Badiera cubensis Britton
In the original description of this species (Bull. Torrey Club
37: 362), I included too many citations of specimens. C.
Wright's Cuban 1913 consists, apparently, of three species; it is
to the specimen with abruptly acuminate leaves cuneate-narrowed
at the base, 4-6 cm. long, that the name should be restricted. As
shown by specimens from Bahia Honda, Pinar del Rio (P. Wilson
9429) the leaves vary to obovate. The fruit is glabrous when
mature, its slender stipe 2 mm. long.
5a. Badiera Fuertesii Urban, Symb. Ant. 7: 244. 1912
A tree of the mountains of Santo Domingo, with glabrous
leaves, strongly reticulate-veined on the upper surface.
6. Badiera Montana Britton
Described from fruiting specimens collected in the Trinidad
Mountains, Santa Clara, Cuba. Flowering specimens with ap-
parently the same foliage and pubescence come from limestone
hills in the vicinity of Sumidero, Pinar del Rio {Shafer 13819), but
flowers from the Trinidad Mountain tree are needed to make the
identity wholly satisfactory.
8. Badiera propinqua sp. nov.
Twigs slender, densely appressed-pubescent. Leaves ovate to
ovate-elliptic, 2-4.5 cm- l°ng. 8-25 mm. wide, bluntly acute or
obtuse and emarginate at the apex, narrowed or obtuse at the
base, sparingly short-pubescent on both sides or becoming glab-
rous, the midvein impressed above, prominent beneath, the slender
lateral veins 6 to 8 on each side of the midvein, the appressed-
pubescent petioles 1.5-3 mm. long; inflorescence few-flowered,
49G Britton: Studies of West Indian plants
4-5 mm. long; bracts ovate, densely pubescent, scarcely 0.5 mm.
long; pedicels slender, apprcssed-pubescent, 1.5-2.5 mm. long;
sepals suborbicular, rounded, pubescent, the larger about 1.3 mm.
long; petals white; keel pubescent on the sides, about 2.5 mm.
long; fruit (from Wright 1913, in part) 10 mm. wide, 7 mm. long,
deeply notched, scarcely margined, glabrous, decurrent on its
stipe, which is about 2 mm. long.
Cuba. Type collected between Los Palacios and San Juan
de Zayas, Pinar del Rio (Shafer 118 18). The description is
drawn to include the part of Wright 191 3, and Wright 3496, pre-
viously referred by me to B. cubensis. The part of Wright 115,
included by me in the original description of B. cubensis, is perhaps
referable here also.
9. Badiera punctata sp. nov.
A shrub about 1 m. high, with slender, ascending, or nearly
erect branches, the twigs densely appressed-pubescent with short
hairs. Leaves ovate to ovate-elliptic, firm in texture, 1.5-2.5 cm.
long, 12 mm. wide or less, obtuse or emarginate at the apex, obtuse
at the base, the midvein impressed above, prominent beneath,
the lateral veins 3 or 4 on each side, the upper surface strongly
punctate, shining and glabrous or nearly so, the under surface
dull, the petioles about 1.5 mm. long; inflorescence few-flowered;
bracts scarcely 0.5 mm. long; fruiting pedicels slender, nearly
glabrous, 2-2.5 mm. long; sepals ovate, obtuse, ciliate, about 1
mm. long; fruit (not quite mature) "green and red," 7 mm. wide,
about as long as wide, shallowly notched at the apex, obliquely
subtruncate at the base, narrowly margined, slightly pubescent,
its stipe 1-1.5 mm. long.
Near a stream, Arroyo del Medio above the falls, Oriente, Cuba
(Shafer 3644). The leaves droop at night, a phenomenon also
observed in B. virgata.
10. Badiera heterophylla sp. nov.
An upright shrub 6 dm. high, the twigs short-pubescent with
somewhat spreading hairs. Leaves of two quite different forms,
(1) narrowly ovate, 3-4 cm. long, 12-18 mm. wide, bluntly acute
at the apex, (2) elliptic, 2-2.5 cm- l°ng. 12-14 mm. wide, rounded
or obtuse at the apex; both forms emarginate at the apex, nar-
rowed or obtuse at the base, sparingly short-pubescent and dull
on both sides, the midvein impressed above, prominent beneath,
the slender lateral veins only 2 or 3 on each side of the midvein,

the appressed-pubescent petioles about 2 mm. long; inflorescence
about 5 mm. long; bracts about 0.5 mm. long; pedicels pubescent,
2 mm. long or less; sepals rounded, pubescent, the larger about
1 mm. long; "flowers yellow"; petals slightly pubescent in the
bud; fruit 7-8 mm. wide, about 5 mm. high, margined, rather
deeply notched, sparingly pubescent when young, glabrous when
mature, slightly decurrent on its stipe which is about 1.5 mm. long.
Deciduous woods, Sierra Nipe, near Woodfred, Oriente, at
450-550 m. altitude (Shafer 3070).

Rocky situations, southern side of Jamaica. Type collected on Great Goat
Island {Harris Q309) ;
The species more resembles P. emarginata than P. obtusa. I am unable to deter-
mine, from the material available at this time, whether P. obtusa occurs on Jamaica or
not. Other specimens referable to P. confusa are: Healthshire Hills near Salt Island
(Britton 3061); base of Healthshire Hills near Salt Ponds (Britton 3036); Great Goat
Island (Harris 10 168; Britton 1874).

1 cm. long, its wing about 1.5 cm. long.
Coastal cliffs and hillsides near the coast, southern Oriente.
Type collected in the basin of Rio Guama, Sevilla Estate near

Dry hillside, La Vigia, Trinidad, Santa Clara {Britton & Wilson
5514). Similar to P. jamaicensis Britton, which is a glabrous
species up to 10 m. high, with broader leaves.
{Harris 9996) is not complete. In 1895, E. Campbell collected a Plumiera at Con-
stant Spring {5073), which may be P. obtusa.
Growing with P. confusa on Great Goat Island there is a Plumiera which has
leaves over 3 dm. long, narrowly oblong to linear-oblong, some of them not more
than 3 cm. wide, and all long-acuminate at the apex (Britton 1870). It was not in
flower at the time of my visit, March 4, 1908, but I obtained its fruit, which is much
like that of P. confusa, and its leaf-venation resembles that of P. confusa also; it
may be that P. confusa is sufficiently heterophyllous to have these narrow, elongated,
long-pointed leaves.

Cyperus nanus Willd.
In Bull. Dept. Agric. Jamaica 5 : Suppl. 1 , 9, 1 noted Mr. C. B.
Clarke's record of this species from Jamaica, as based on the same
specimen (March 13) as his record of Mariscus gracilis Vahl
(Cyperus granulans [Desf.] Britton), and I subsequently ascer-
tained that this specimen preserved in the Kew herbarium is

C. granulans. It would therefore appear that C. nanus was
entered as Jamaican by Mr. Clarke in error. C. granulans on
the other hand is now known to me to inhabit dry soil at Long
Acre Point near Black River (Britton 1383).
Cyperus ignotus sp. nov.
Perennial, glabrous; culm rather stout, smooth, bluntly 3-
angled, about 5 dm. high. Basal leaves as long as the culm or
longer, smooth, 2.5-4 mm. wide, those of the involucre similar,
much longer than the inflorescence, sometimes 3 dm. long; umbel
compound, its primary rays 8 cm. long or less; spikelets compressed,
capitate, 6-8-flowered, the heads numerous, 8-10 mm. in diameter;
rachis wingless; scales ovate-lanceolate, mucronulate, very faintly
nerved, closely appressed and overlapping, 2 mm. long; style 3-
cleft; achene oblong, trigonous, 1.3 mm. long, about twice as long
as thick, narrowed at both ends.

Scirpus nodulosus Roth, Nov. PI. Sp. 29. 1821.
Swamp, Belle Vue near Spanish Town {Harris 12179).
Distribution: Southern United States; Cuba; Hispaniola;
Porto Rico; Antigua; Guadeloupe; continental tropical America.
Eleocharis microcarpa Torr. (E. minima Kunth), was re-
corded by Mr. Clarke as collected in Jamaica by Purdie, but his
determination of the specimen from the interior of Manchester
preserved in the Kew herbarium was subsequently doubted by
Mr. Clarke, and we have no other knowledge of the existence of
this species in Jamaica.
Stenophyllus junciformis (HBK.)
I sol epis junciformis HBK. Nov. Gen. 1: 222. 1815.

Ridge, St. Andrew (Harris 12219, I2345)-
Distribution: Cuba; South America.
Britton: Studies of West Indian plants 443
Owing to two different species having been distributed as
Scirpus juncoides under C. Wright's Cuban No. 1533, I formerly
misidentified Professor Underwood's No. 3364 and recorded it*
as Stenophyllus subaphyllus (Clarke) Britton, a species apparently
restricted to eastern Cuba.

Isle of Pines, Cuba.
45. STENOPHYLLUS Raf. IN THE WEST INDIES
Type species: Scirpus Stenophyllus Ell. The generic name
dates from 1825 (Neog. 4). The name Bulbostylis, taken up by
Mr. C. B.Clarke for the genus in 1893 (Hook. f. Fl. Brit. India)
and subsequently, was first published by Kunth, under Isolepis,
in 1837 (Enum. 2: 205).

48. THE GENUS HEPTANTHUS Griseb.
A Cuban genus, of which three species were described at the
place of original publication (Cat. PI. Cub. 148. 1866); all were
from western Cuba, H. cochlearifolius Griseb. being typical, and
none have since been added to the genus. I now propose three
others, all from eastern Cuba.

I. Heptanthus cochlearifolius Griseb. Cat. PI. Cub. 148.
1866
Type locality: Western Cuba.
Distribution: Pine-lands and savannas, Pinar del Rio.
The upper leaf-surfaces are glabrous or nearly so.
A plant related in leaf-form, but with the upper leaf-surfaces
densely puberulent is common in pine-lands and white sand in the
central districts of the Isle of Pines, but could not be found in
flower during our visit to this region in February and March, 1916
(Britton & Wilson 14163) ; it is therefore referred to this species,
with doubt.

Sebesten brachycalyx (Urban)
Cordia Sebestena brachycalyx Urban, Symb. Ant. 1: 389. 1899.
This tree, first made known from the southern and eastern
coasts of Porto Rico, appears to differ specifically from the related
Sebesten Sebestena (L.) Britton {Cordia Sebestena L.) of wide dis-
tribution in the West Indies, Florida and tropical continental
America, and there much planted for ornament. S. brachycalyx
has much rougher upper leaf-surfaces and a much smoother calyx
than S. Sebestena (often glabrous), and its yellow or orange fruit
is shorter-beaked than the white fruit of that species; the corolla of
S. brachycalyx has a narrower limb than that of S. Sebestena. The
species inhabits Porto Rico, Vieques, Culebra, and Buck Island,
St. Thomas.

52. CLEOME PROCUMBENS Jacq. AND ITS RELATIVES
The small, simple-leaved Cleomes of the West Indies, form an
interesting and peculiar group of the genus, very different in
habit and aspect from the large, typical, compound-leaved ones.
Seven species appear to be represented.
Annuals or biennials.
Pedicels filiform.
Leaves linear-oblong; pod subterete. 1. C. Sloanei.
Leaves filiform; pod compressed. 2. C. guianensis.
Pedicels very short; leaves very narrowly linear. 3. C. stenophylla.
Perennials with woody roots.
Pod acute or acuminate; leaves linear to oblong, acute or
acuminate.
Leaves acuminate; pedicels half as long as the pods. 4. C. procumbens.
Leaves acute; pedicels as long as the pods or longer.
Petals about 4 mm. long; leaves oblong to oblong-
lanceolate. 5. C. Wrightii.
Petals 8-10 mm. long; leaves narrowly linear. 6. C.macrorhiza.
Pod obtuse; leaves ovate or elliptic, obtuse or rounded. 7. C. obticsa.
I. Cleome Sloanei Urban, Symb. Ant. 5: 347. 1907
Grassy and sandy places, at low elevations, southern side of
Jamaica.
This species is referred by Fawcett and Rendle, as previously
by other authors, to C. procumbens Jacq., which is, apparently,
confined to Hispaniola.

4. Cleome procumbens Jacq. Stirp. Am. 189. pi. 120. 1763
Hispaniola. Erroneously recorded from Cuba, and, appar-
ently also erroneously referred to Jamaica, as Jacquin's figure of
the type would seem to represent a well-marked species, not
collected since its original discovery.

rounded at the base, the midvein prominent, the lateral venation
obscure, the petioles 1-2 mm. long; peduncles slender or filiform,
4-8 mm. long; sepals obtuse, 2-2.5 mm. long; petals yellow,
oblong or oblong-obovate, obtuse or acutish, 3-4 mm. long;
stamens about two-thirds as long as the petals; filaments filiform;
style about 1 mm. long; capsule elliptic, elliptic-obovate or oblong,
compressed, 3-6 mm. long, 2-2.5 mm- wide, obtuse at the apex,
somewhat narrowed at the base, few-several-seeded.

?Cassia stricta Schrank, Hort. Monac. i: pi. 34. 1819.
Chamaecrista virgata Greene, Pittonia 4:31. 1899.
Type locality : Jamaica.
Distribution: Jamaica.
Illustrations: Bot. Mag. pi. 3435; Schrank, loc. cit.
Linnaeus included, in his citations of synonyms of this species,
several others, but his description of it, together with his having
received a Jamaica specimen from the collection of Patrick Browne,
prior to his publication, as I am informed by Dr. B. Daydon
Jackson, Secretary of the Linnaean Society of London, show that
the name is to be restricted to the Jamaica plant. Subsequent
authors have confused it with species from other islands and from
continental tropical America. The identity of Cassia virgata Sw.
was established for me by Mr. William Fawcett at the British
Museum of Natural History. Cassia stricta Schrank, from the
illustration and the Jamaica habitat, appears referable here, but
Schrank's description of the plant is not altogether conclusive;
he says the root is annual.
18. Chamaecrista Dussii sp. nov.
Perennial, villous-pubescent, erect, simple, 5-9 dm. high, some-
what woody. Stipules narrowly lanceolate, strongly striate, 10-
12 mm. long; leaves 5-7 cm. long; petiolar gland close to the
lowest leaflets, scutelliform, sessile, slightly concave, nearly 1 mm.
in diameter; leaflets about 17 pairs, linear, pubescent on both
sides, 10-18 mm. long, 2-3 mm. wide, obtuse, mucronate, in-
equilateral, the mid vein excentric, the lateral veins few and
distant; peduncles 4-6 mm. long; sepals lanceolate, acuminate,
pubescent, about 7 mm. long; petals obovate, 8-10 mm. long;
pod linear, slightly curved, villous-pubescent, obliquely short-
tipped, 3 cm. long, 5 mm. wide.
Guadeloupe and Martinique. Type from Trou-Vaillant, Par-
nasse, Martinique (Pere Duss 1121).
19. Chamaecrista Swartzii (Wickstr.)
Cassia Swartzii Wikstr. Vetensk. Acad. Handl. 1825: 430. 1826.
Chamaecrista complexa Pollard, Field Col. Mus. Bot. 2: 47. 1900.
Type locality: St. Bart's.
Distribution: Porto Rico; Vieques; Culebra; St. Thomas;
St. Jan; Tortola; St. Croix; Saba; St. Bart's; St. Kitt's; Dominica;
Guadeloupe; Grenada.
10 Britton: Studies of West Indian plants
The species has been much confused with the Jamaican C.
glandulosa.
20. Chamaecrista polyadena (DC.)
Cassia polyadena DC. Mem. Soc. Hist. Nat. Gen. 2: 132. 1824.
Type locality : Guadeloupe.
Distribution: Guadaloupe; Dominica; Martinique; Barba-
does.
My identification of this species is based on my examination of
the type, some years ago, in the Candollean herbarium at Geneva,
Switzerland. Notwithstanding the usually sessile petiolar gland
and the relatively broader leaflets, I am not confident that this
species is distinct from the preceding one.
21. Chamaecrista pygmaea (DC.)
Cassia pygmaea DC. Mem. Soc. Hist. Nat. Gen. 2: 131. 1824.
Type locality: Santo Domingo.
Distribution: Hispaniola.
Referred by Bentham to Cassia procumbens L., which is a
synonym of C. nictitans L. of continental North America, as
previously indicated by me (Bull. Torrey Club 43: 463).
22. Chamaecrista patellaria (DC.) Greene, Pittonia 4: 32.
1899
Cassia patellaria DC; Collad. Cass. 125. 1816.
Type locality : Cayenne.
Distribution: Jamaica; all provinces of Cuba and on the Isle
of Pines; continental tropical America.
Illustration: Collad. Cass. pi. 16.
23. Chamaecrista fasciata Britton, Bull. Torrey Club 37: 352.

Distribution: Savannas and pine-lands, Pinar del Rio and
Isle of Pines, Cuba.
26. Chamaecrista micrantha Britton, Bull. Torrey Club 43:
463. 1916
Type locality: Near San Pedro, Isle of Pines, Cuba.
Distribution: Pine-lands and savannas, Pinar del Rio and
Isle of Pines, Cuba. Referred by Grisebach to Cassia pygmaea
DC.
27. Chamaecrista riparia (HBK.)
Cassia riparia HBK. Nov. Gen. 6: 369. 1824.
Type locality: Banks of the Magdelena River near Mompox.
Distribution: Jamaica; province of Havana, Cuba; Grand
Cayman; Andros, New Providence and Eleuthera, Bahamas;
northern South America and recorded from Central America.
The plant of the Bahamas was referred by me with some doubt
(Bull. N. Y. Bot. Gard. 3: 443) to Cassia aspera Muhl., which it
closely resembles, except in the petiolar gland. Cuban and
Jamaican specimens differ from the Bahaman in having the "gland
somewhat longer-stalked.
I have not been able to study an authentic specimen of C.
riparia. Bentham's record of it as West Indian was based upon
a plant collected in Cuba by Liebmann, preserved in the Kew
herbarium.

Distribution: Known definitely only from the type locality.
Rugel's label indicates that this is a shrub growing in rocks.
The species is related to the following one. Grisebach considered
the plant to be the same as R. Berteriana A. Rich, (not DC),
which was collected at La Cabana, Havana. R. Berteriana DC,
of Hispaniola, is clearly different.

leaves acute at both ends, bipartite, persistent, obtuse stipules;
corymbose peduncled flowers, the calyx truncate, with five short
teeth. The genus of this plant was questioned by A. Richard
(in Sagra, Hist. Cub. n : 13), and I do not know any species which
answers to the description.
Rondeletia americana L. Sp. PI. 172. 1753
This, the type of the genus, is also recorded by De Candolle
as found at Havana by Ossa, and Grisebach (Fl. Br. W. I. 327)
mentions it as Cuban. I know the plant only from St. Vincent
and Jamaica.
Rondeletia laevigata Ait. Hort. Kew. ed. 2, 1: 366. 18 10
De Candolle mentions this also as found at Havana, but no
species answering to the description is known to me from Cuba;
Grisebach (Fl. Br. W. I. 328) indicates that it is from the island
of Trinidad.
Rondeletia leptacantha DC. Prodr. 4: 410. 1830
Collected by Ossa, near Havana, according to De Candolle.
Described as a plant with opposite spines, broadly oval, subacute
leaves, the twigs and leaves subpilose when young, the slender
peduncle as long as the leaves or longer, three- to five-flowered at the
apex. No species of Rondeletia known to me answers the description.
Grisebach (Cat. PI. Cub. 133) refers the plant to Chomelia fascicu-
lata Sw. [Anisomeris fasciculata (Sw.) Schum.], but this disposal
of it is not satisfactory.

times laciniate at the apex, about equalling the corolla or exceeding
it; corolla-lobes ovate; anthers about 0.15 mm. long; sepals of
the pistillate flowers about 1.5 mm. long, boat-shaped, strongly
keeled and crested above the middle, acuminate; petals linear-
elliptic to linear-spatulate, 1.5-2 mm. long; capsule suborbicular
or orbicular-ovoid, about 0.5 mm. wide: seeds narrowly oval,
about 0.5 mm. long.
Pinelands, Siguanea {Britton Sf Wilson 14Q51).
This differs from all described Cuban species of Eriocaulon.
Its short stiff scapes and fusiform glabrous or nearly glabrous
heads are particularly diagnostic.
Eriocaulon ovoideum Britton & Small, sp. nov.
Plants 6-1 1 cm. tall, the scapes tufted, usually densely so;
leaves erect or ascending, narrowly linear-lanceolate to linear-

stoutish, spirally- twisted, sharply 5-angled, each subtended by an
obliquely opened sheath which is as long as the leaves or shorter;
heads very dense, ovoid or globose-ovoid, becoming 6-8 mm. long,
obtuse, tan-colored; bracts of the involucre ovate to oblong, 1.5-3
mm. long, obtuse, glabrous, chartaceous; flowers numerous; bracts
subreniform, mostly wider than long, broadly rounded at the apex,
scarious, minutely pubescent; sepals of the staminate flowers
obovate to cuneate, concave, fully 1 mm. long, erose at the apex,
mostly exceeding the corolla; anthers ovoid, about 0.1 mm. long;

keel-winged and crested on the back, abruptly pointed: petals
spatulate, about 1.5 mm. long, often erose at the apex; capsule
reniform, about 1 mm. wide; seeds broadly oval, fully 0.5 mm.
long.

Hitherto known only from Tortola, where Dr. Shafer made a
second collection of it in 1913. A tree, 6-8 m. high, very different
from typical species of Sida.
OSSAEA DOMINGENSIS Cogn.
Alto de la Bandera, Porto Rico {F. L, Stevens 8717). Hitherto

Lescaillea equisetiformis Griseb.
This monotypic genus of Compositae was rediscovered on the
southern slope of Cajalbana in the province of Pinar del Rio,
Cuba, by Brothers Leon and Charles on April 6, 191 5. The
genus has hitherto been imperfectly known, as it was represented
in this country only by a fragment at the Gray Herbarium,
collected by Charles Wright in western Cuba. Lascaillea is a
woody vine related to Porophyllum. The leaves are reduced to
small scales, the plant resembling certain species of Ephedra
much more closely than it does any Eguisetum.

I am indebted to Mr. N. E. Brown for comparing this little
plant with West Indian and South American species in the Kew
Herbarium, where he was unable to match it. He remarks upon
its unusual character of having both terminal and basal spikelets,
and compares it with Chaetocyperus Jamesoni Steud. from Guaya-
quil, Ecuador (Jameson 360), pointing out important differences,
however.

Specimens of this plant were mixed by Grisebach with those
of another and the complex described by him (Fl. Br. W. I. 143)
as Thibaudia latifolia Griseb., subsequently referred by Bentham
and Hooker to Vaccinium; it would appear that the name latifolia
should go with this other species, which, however, is not a good
Vaccinium.
Sophoclesia trinitensis sp. nov.
Pendent from forest trees; stem slender, sparingly branched,
short-villous when young, 1-4 m. long. Leaves subcoriaceous,
glabrous or nearly so, ovate or some of them ovate-lanceolate, 1.5-

Climbing on forest trees, Heights of Aripo, Trinidad {Britton
and Freeman 2364, March 16, 192 1). Specimens were brought
from the same place a few days earlier by Mr. F. W. Urich, Ento-
mologist of the Trinidad Department of Agriculture, and he
guided us to it. The plant from which the type specimens were
taken is wonderfully elegant when in bloom, displaying long

The flowers are too young to enable the generic status of this
tree to be certainly determined. Mr. N. E. Brown has identified
specimens as the same as Crueger's no. 247 in the Kew Herbarium,
from Trinidad, which is a leafy branch and a detached fruit.
The leaves are also the same as those of Trinidad Herbarium
no. 1454. also leafy shoots with the remains of a fruit which was.
apparently, about 2 cm. long, attached, and with some flowers
even younger than those of our 2403.

R. turquinensis is a member of the Adenotrichi, differing from
R. costaricanus and R. adenotrichos in the narrower lanceolate
long-acuminate, instead of broadly ovate, abruptly acuminate
leaflets; from R. Vera-Crucis in the more dense pubescence and
the texture of the leaves. It is more closely related to R.
irasuensis and R. miser. In habit, leaf-form, and pubescence it
resembles the former, but the inflorescence is mostly simple, the
sepals narrower, and the drupelets perfectly glabrous; neither
have any 5-foliolate leaves been seen. From R. miser it differs
in the shorter sepals and the thicker leaflets, with shorter petioles,
more numerous and more prominent lateral veins, and much
closer serrations.

Among North American species Poly gala rhynchosperma is
nearest P. paniculata L., which is densely stipitate-glandular
and has shorter wings and an erostrate seed. The Venezuelan
P. Funkii Chod., known to me only from Chodat's description
and figures, is evidently closely related, having similar bracts,
seed, and stigma. It is. described as glabrous, with acute lance-
elliptic sepals, acute wings, and a crest composed on each side
of an acute triangular entire lamina and an undivided linear
lobe.

perennial root resembling P. Wrightii Chod., which is densely
incurved-puberulous and has the sepals ciliate with eglandular

Kallstroemia incana Rydberg, sp. now
KaUstr.oemiu cariba< rban, Symb. Ant. 8:319. 1920. Not
K. caribaea Rydberg, 1910.
A diffusely branched herb, somewli.it woody at the base;
stems spreading, 2-3 dm. long, with coarser spreading and finer
more appressecl hairs, terete; stipules linear-oblong, 2-3 mm.
long, tardily deciduous; leaves I— 1.5 cm. long; petioles 2-3 mm.
long; leaflets mostly 3 pairs, obliquely ovate, 3—5 mm. long,
hoary on both sides, acutish; peduncles 2-3 mm. long; sepals
lance-linear, acute, 3 mm. long; petals elliptic-obovate, light
yellow, 3 mm. long; fruit grayish-strigose, about 5 mm. broad,
the beak 2 mm. long, conic at the base; carpels cross-ridged on
the back and reticulate on the faces.
Type collected at Barahona, Santo Domingo, July 1920,
Fuertes 418 (herbarium of the New York Botanical Garden);
also collected at Rincon, October 191 1, Fuertes 1352.
The two numbers cited were determined by Urban as K.
caribaea and included under that name in his Flora Domingensis,
but it differs in the hoary pubescence, the small leaflets, the small
petals, scarcely half as long as in K. caribaea, the short peduncles
and short beak on the small fruit. It approaches more K. carta
Rydberg, from ( "uracao.w it h which it has the following characters
in common: small leaflets, short peduncles, small petals ami
fruit, and short beak; but it is more canescenl, more branched,
with shorterinternodes and smaller lea\ es.and the beak different,
not at all swollen.

70. UNDESCRIBED SPECIES FROM TRINIDAD
Anthurium aripoense N. E. Brown, sp. nov.
Glabrous in all parts. Petioles about 75 cm. long and (when
dried) 4 mm. thick, sheathing for about 7 cm. at their base,
apparently more or less flattened above with obtuse edges,
rounded on the back; blades about 34 cm. long, 26 cm. broad
across the basal lobes and 18 J2 cm. broad at the constriction,
cordate, with the basal lobes slightly constricted into the front
lobe at about 1 1 cm. above the insertion of the petiole ; basal sinus
about 4 cm. deep, broadly open, rounded; basal lobes semi-
orbicular; front lobe ovate, abruptly acute, apiculate; both
surfaces green; basal nerves 4 on each side of the midrib, the 3
outer united and denuded at the sinus for about 25 mm., much
curved and all excurrent at the margin below the middle of the
leaf; the inner one free, ascending and excurrent at the apex,
running subparallel with the margin at about 12-15 mm.

Heights of Aripo, {Broadway 9924).
The venation of the leaf of this species is on the same plan
as that of A. Guildingii Schott, but in outline the slight constric-
tion above the basal lobes brings it nearer to A. panduraeforme
Schott.

margin; stipules formed of a number of small teeth 1 mm. long
between the bases of the petioles. Cymes axillary pedunculate,
6-8 cm. in diameter, quite glabrous in all parts; peduncle 3-4
cm. long, nearly 2 mm. thick. Pedicels 15-25 mm. long. Sepals
10 mm. long and 4-5 mm. broad, oblong, obtuse, rather thick;
at the base of each sepal, between it and the corolla is a broadly
deltoid-ovate obtuse gland about 1 mm. long. Corolla only seen
in bud and in that condition the tube is 12 mm. long and 3 mm.
in diameter, cylindric, not dilated at any part, surmounted by a
truncate-based actite cone 5 mm. long and 6V2 mm. in dia-
meter formed by the contorted lobes; mouth of the tube raised
within into a distinct rim about 1 mm. high, without processes
or other appendages; lobes as unfolded from the bud 5 mm.
long and 6 mm. broad, suborbicular, entire. Stamens inserted

spreading; petiole 4-6 mm. long, minutely puberulous; blade
6 Rrition : Sitdiivs of West Indian pi.. wis XII
2-6 cm. long, 15 30 mm. broad, ovate or oblong-lanceolate,
acuminate, rounded at the base, glabrous on both sides to the eye,
but with a microscopic scattered pubescence above, where the
midrib is also minutely puberulous; primary veins 3- 5 on each
side of the midrib, distant, inarching and uniting into a sub-
marginal vein 2 3 mm. from the margin, not prominent on either
surface. Flowers in small sessile umbellate clusters at the nodes
of leafless branches. Bracts very minute. Pedicels 2-2 V2 mm.
long, and together with the flowering branches minutely puberu-
lous. Calyx 5-lobed to the base; lobes about % mm. long, ovate,
obtuse, think- and very minutely puberulous. Corolla about
3 mm. in diameter; tube about 0.75 mm. long. glabrous; lobes
spreading, about 1 mm. long, ovate, subacute, minutely and
densely puberulous within; each sinus with a thickening or slight
gibbosity, which seems nearly or quite to touch the staminal
column so as to form 5 small pocket-like entrances to the tube at
the base of the lobes. Staminal column subsessile, about 0.75 mm.
long, somewhat conical, truncate at the apex. Corona of 5
lobes arising from the staminal column at the base of the anthers,
minute, about :4 mm. long, pressed close against the back of
the anthers and shorter than the latter, ovate, obtuse; they seem
to be connected at the base by a minute tooth under the anther-
wings, but in the dried flowers this is difficult to determine.
Trinidad (Dannouse 6419, type). Collected in 1898.
The genus Decastelma is very like Metastclma in appearance,
but differs by having the staminal column subsessile instead of
with a long stipe, and by the corona arising from the staminal
column at the base of the anthers instead of at the mouth of the
corolla-tube. But the description of the corona of Decastelma
as given by Schlechter is entirely wrong, unless the flowers on
different specimens vary very much. For in the type of the
genus, D. Broadwayi Schltr. (Broadway 474), the flowers that I
have examined have a corona consisting of 5 lobes only, which
are shorter than the staminal column and pressed close to it;
they are broader than long and somewhat truncate at the three-
toothed top, the middle tooth being minute.
Probably some species from South America, now placed under
the genus Metastelma, really belong to Decastelma.

74. UNDESCRIBED SPECIES FROM CUBA
Andropogon virginicus graciliformis Leon, var. nov.
Lower sheaths not equitant, rather terete, glabrous; culms
slender and cylindrical from the base, usually producing one or
two flowering branches, only from the two or three upper nodes;
nodes of the inflorescence long pilose; blades at first narrowly in-
volute or conduplicate from base to apex, becoming flat and
flexuous in age, only about 1.5 mm. wide, devoid of long hairs
towards the base; spathes becoming reddish, the upper ones 6
to 9 cm. long, much longer than the racemes.
Gravelly soil, Sabana de Motembo, Santa Clara, Cuba {Leon
and Loustalot 11343). This variety may be readily recognized
by its basal sheaths not strongly compressed and equitant as
those of typical Andropogon virginicus and in its long and very
slender stems and narrow leaves. The type specimen is pre-
served in the herbarium of Colegio de la Salle, Vedado, Havana.
We are indebted to Prof. A. S. Hitchcock and Mrs. Agnes Chase
for suggestions and help.
Paspalum motembense Leon, sp. nov.

long; blades 20 to 30 cm. long, up to 5 mm. wide, glabrous on
both surfaces, scaberulous on the border, conduplicate, acuminate
at the convolute apex; panicle short exerted, 15 cm. long, the
rachis angled; racemes several, ascending, 2 to 5 cm. long, erect

sterile lemma faintly 3-nerved, fruit brown, slightly rugose,
shining.
Grassy place, Sabana de Motembo, Santa Clara, Cuba {Leon
and Loustalot 9354)- Related to the South American P. hydro-
phyllum Henr., a much more robust plant, and to the Cuban
P. JVrightii; this is taller and stiffer than P. motembense, from

equal, ascending, the central one slightly recurved, 2 to 3 cm.
long, the lateral ones somewhat approximate, one-half as long
as the central one or little more.
Arid rocky silicious hillside, Peladeros de Jauco, southwest
of Baracoa, Oriente, Cuba (Leon 12299).
This species is allied to A. divaricata Humb. & Bonpl. of
Mexico, but may be distinguished by its much longer and closely
involute leaves. It is named in honor of Sr. Enrique Prada of
Jauco, who helped very efficiently in collecting work. The
type specimen is preserved in Colegio de la Salle Herbarium,
Vedado, Havana.

marginal nerves from base to apex, and often on the keel, from
above the base to the middle, the awn 8 to 12 mm. long; sterile
lemma I to 2.2 mm. long, wider below the apex than at base,
acute at apex, its awn 6 to 10 mm. long; some of the lower spike-
lets include sometimes a second awned sterile floret.
In sandy ground, at Cajobabo, not far from the mouth of
Jojo River, Oriente, Cuba (Leon 12320). Named in honor of
Colonel Morales Coello of the Cuban Navy, in recognition of his

mucronate pink outer bract 5-6 cm. long and 4-5 cm. broad.
Flowers numerous in each cluster or head. Bracts about 3-3}^
cm. long, 10-15 mm. broad, ovate-lanceolate, acute, tipped with
a spine 3-4 mm. long, slightly woolly or becoming glabrous.
Sepals 15 mm. long, spine-tipped, the lower two-thirds having
unequal membranous inrolled margins, one margin about 3 mm.
broad and the other 1 mm. broad and more acutely narrowed
into the spine than the broad margin, woolly. Petals not seen
in perfect condition, but apparently about as long as the sepals
and lanceolate. Stamens about three-fourths as long as the
petals, absent in two flowers examined; anthers 3^ mm. long,
versatile, oblong, with a blunt mucro. Style rather shorter
than the stamens; stigma entire.

1926] BRITTON": WEST INDIAN PLANTS 467
I have placed this very distinct plant under Gravisia because
in general appearance it seems more nearly allied to G. aquilega
Mez, than to any other in the Kew Herbarium. But the flowers
are not in a sufficiently good state to admit of complete details
being given. I could not, however, detect any ligules upon the
petals, nor did I find any pollen to examine. The habit of its
inflorescence would seem to distinguish it from Aechmea. [N. E.

A species allied to Elsota coriacea (Bonpl.) Blake and to
E. sylvestris (Schlecht.) Kuntze, and characterized primarily by
the numerous thick blunt crests of the fruiting cell. The de-
scription of Securidaca tenuijolia Chod., of Trinidad, suggests
this species, but a fruit received from Berlin of Trinidad Bot.

S. tenuijolia, proves to be entirely different from the fruit of
E. lophosoma.

Balandra Bay, Trinidad, {IV. G. Freeman njio).
The genus Metastelma is one that urgently requires a thor-
ough revision, for as understood by modern authors and as de-
fined in Bentham & Hooker, Genera Plantarum 2: 755, it com-
prises three very distinct types of coronal structure, which in
other parts of the order are held to constitute generic distinction,
and there seems no valid reason why these differences should not
be considered of generic value in this case. The three types are:
1, Plants with the coronal lobes inserted at the sinuses of the
corolla. 2, Plants with the coronal lobes inserted at the base of
the staminal column. 3, Plants with the coronal lobes inserted
at the top of the staminal column.
Originally the genus Metastelma was founded by Robert
Brown upon a plant collected in the Islands of St. Croix and St.
Christopher, having the coronal lobes inserted at the sinuses of
the corolla (type 1). This plant (M. parviflorum R. Br.) 1 find
upon comparison with the type to be identical with Thompson
499, collected on St. Croix, and M. Freemani, above described,
has the same type of structure and undoubtedly is a true species
of Metastelma. But modern authors seems to have understood
type 2 as being the typical structure of Metastelma. While
K. Schumann in Engler, Pflanzenfamilien 42: 229 has placed
plants having the typical structure of Metastelma (i. e. type 1)
under the genus Irmischia, founded by Schlechtendahl in Lin-
naea 19: 738 upon a Mexican plant I have not seen, but which
from description may prove to be a typical Metastelma; in which
case Irmischia will rank as a svnonvm of Metastelma.

As to types 2 and 3 mentioned above, I consider that these
should be separated from Melastelma and made to constitute
separate genera. [N. hi. Brown\]

petioles; inflorescence subcapitate, several-flowered; corolla blue
to lavender, about 1.5 cm. in diameter.
Thickets, Trinidad, Tobago and northern Venezuela. Type
from Manzanilla, Trinidad {Britton 2 191). This plant has been

Chimarrhis microcarpa Standley, sp. nov.
Branchlets stout, obtusely angulate, ochraceous, glabrous,
the internodes 5-13 mm. long; stipules lance-oblong, attenuate,
3 cm. long, thin, brown, glabrous, caducous; leaves opposite,
the petioles slender, glabrous, 2.5 cm. long; leaf blades elliptic,
11-19 cm. long, 5-8 cm. wide, acute, at base acute and decurrent
upon the petiole, membranaceous, glabrous, the lateral nerves
about 10 pairs, arcuate, laxly and irregularly anastomosing close
to the margin; inflorescences axillary, cymose-paniculate, halt

brown, glabrous, crowned by the low persistent calyx.
Type in the herbarium of the New York Botanical Garden,
collected at Maraval, Trinidad, in 1904 (I. Dannouse 6946).
Because of the incompleteness of the available material, there
is some doubt as to the proper reference of this plant to Chimar-
rhis, but it agrees well with that genus in the characters exhibited
by the specimen studied.
