7. Homalium leiogynum Blake, sp. nov. 
Older branches clothed with a gray bark, the younger fuscous brown, glabrous; leaf 
blades 6 to 9.5 cm. long, 3 to4 cm. wide, elliptic to oval, abruptly or gradually pointed, 
acute or acuminate at tip, rarely obtuse, at base rounded or rounded-cuneate, perga- 
mentaceous, undulate-crenate, above glabrous, beneath sparsely barbellate in the 
axils or glabrous, reticulate-veined on both sides, with 6 or 7 pairs of lateral veins; 
petioles glabrous, 2 to 5 mm. long; peduncles glabrous, axillary and subterminal, 1.7 
to 3.5 cm. long; racemes simple, the rachis sparsely puberulous, 1.2 to 4.5 em. long, 
rather loosely flowered; pedicels 1.2 to 2.6 mm. long, incurved-puberulous; flowering 
calyx slenderly turbinate, narrowed into a pediform base, 5 to 7-sulcate, sparsely 
puberulous with subappressed hairs; calyx segments 5 to 7, lanceolate or ovate- 
lanceolate, narrowed to an obtuse tip, outside sparsely, within more densely puberu- 
lous with subappressed hairs and ciliolate, 3.2 to 4 mm. long, 1 to 1.2 mm. wide; 
corolla in flower 9.5 to 11.5 mm. wide; petals elliptic-ovate or lance-ovate, acutish or 
obtuse, puberulous and ciliolate, 4.4 to 4.6 mm. long, 1.3 to 2.2 mm. wide; stamens 
in fascicles of 4 to 6, the filaments glabrous, shorter than the petals; glands oblate, 
griseous-puberulous; styles 3 or 4, glabrous, united at base into a glabrous column; 
ovary conic, glabrous or with a very few long hairs. 
Typein the U.S. National Herbarium, no. 462,116, collected in dry woods at Fajardo, 
Porto Rico, April 7, 1899, by Mr. and Mrs. A. A. Heller (no. 992). A specimen of the 
same collection is in the herbarium of the New York Botanical Garden. 
Homalium leiogynum is readily distinguished by its glabrous ovary and 4 to 6- 
androus fascicles of stamens. 
8. Homalium hemisystylum Blake, sp. nov. 
Older branches grayish, glabrous, the younger fuscous or fuscous gray, glabrous or 
very finely puberulent; leaf blades 4.5 to 8.8 cm. long, 2.3 to 6 cm. wide, oval or 
elliptic, short-pointed, rounded at base, coarsely crenate, subcoriaceous, above 
glabrous, beneath barbellate in the axils or sometimes entirely glabrous; petioles 
glabrous, 2 to 7 mm. long; peduncles axillary and subterminal, sparsely incurved- 
puberulous or sometimes glabrate, 1.5 to 2.7 cm. long; racemes simple, loosely 
flowered, the axis sparsely incurved-puberulous, 1.5 to 4.5 cm. long; pedicels 1 to 
2 mm, long; fruiting calyx tube slenderly turbinate, contracted gradually into a 
pediform base, finely incurved-puberulous; calyx segments 5 to 7, ovate or lance- 
ovate to lanceolate, narrowed to the acutish or obtuse tip, sparsely puberulous outside, 
densely griseous-puberulous within, 3.5 to 4 mm. long, 0.7 to 1.8 mm. wide; corolla 
11 to 13 mm. wide; petals ovate or oblong-ovate, obtusish, rather densely griseous- 
puberulous on both sides, 4.5 to 5.5 mm. long, 1.8 to 2.5 mm. wide; stamens in 
fascicles of 3 or 4, or rarely 5, the filaments glabrous, shorter than the petals; styles 
3 or 4, glabrous, united at base into a glabrous or sparsely pilose column about one- 
third their length; ovary conic, sordid-villous, usually glabrous or nearly so toward 
the margin of the broad base. 
Type in the U.S. National Herbarium, no. 430,335, collected in the Sierra de 
Luquillo, Porto Rico, June 15, 1902, by Percy Wilson (no. 259). 
OTHER SPECIMENS EXAMINED: 
Porro Rico: Wooded hill, Colonia San Miguel, near Fajardo, March, 1918, 
Britton & Shafer 1620 (N). Mountain forest, altitude 900 meters, Mt. 
Alegrillo, April, 1913, Britton, Stevens & Hess 2589 (N). Duplicates of the 
type, Wilson 259 (Y). 
Most nearly related to H. leiogynum, but separable by the smaller fascicles of stamens 
and by the villous ovary. 
9. Homalium racemosum Jacq. Enum. Pl. Carib. 24. 1760. 
Older branches gray-barked, the younger fuscous, glabrous, marked with whitish 
lenticels; leaf blades 8 to 12.5 em. loug, 3.7 to 6 em. wide, el'iptic or ovate-elliptic, 
acuminate to a blunt tip, cuneate to rounded at base, pergamentaceous, crenate or 
ie
