BLAKE—AMERICAN SPECIES OF HOMALIUM. 231 
12. Homalium trichocladum Blake, sp. nov. 
Tree; older branchlets grayish, glabrous, the younger fuscous, densely incurved- 
puberulous and spreading-pilose with griseous hairs; leaf blades 4.2 to 9.5 cm. long, 
2.8 to 4.7 cm. wide, elliptic, oblong-elliptic, or oval, obtuse or short-pointed, with 
obtuse tip, rarely rounded or subtruncate, at base cuneate, rounded, or subtruncate, 
crenate-serrate, with 12 to 19 pairs of blunt teeth, somewhat shining above, paler 
beneath, membranaceous-chartaceous, above puberulous along costa and slightly so 
along the lateral veins (these 7 or & pairs), on surface very sparsely pubescent or 
glabrous, beneath along veins spreading-pilosulous, barbeilate in the axils, between 
the veins rather sparsely but softly incurved or ascending-pilosulous; petioles 
densely puberulous and pilose, 3 to 7 mm. long; peduncles axillary and sub- 
terminal, solitary, densely incurved-puberulous and spreading-pilose, 2.5 cm. 
long; racemes simple, loosely few-flowered, the rachis 1.5 to 3.5 cm. long; pedi- 
cels 1.7 to 2.5 mm. long; calyx tube turbinate in flower, contracted into a pediform 
base, griseous-puberulous; calyx segments 5, ovate or lance-ovate, narrowed to an 
obtusish tip, griseous-puberulous on both sides, 3.4 to 4 mm. long, 1.2 to 1.4 mm. 
wide; corolla white, 9 to 12 mm. wide in flower; petals 5, ovate or ovate-lanceolate, 
narrowed to an obtusish tip, griseous-puberulous on both sides, 4.3 to 5.3 mm, long, 
1.5 to 2.3mm. wide; stamens in fascicles of 3, the filaments glabrous, much ‘shorter 
than the petals; styles 3, distinct to base, hairy below the middle; ovary short- 
conic, densely griseous-villous. 
Type in the Gray Herbarium, collected in the Province of Barahona, Santo Domingo, 
June, 1911, by Padre Miguel Fuertes (no. 1098). 
A shect of sterile specimens in the herbarium of the New York Botanical Garden, 
collected by Britton and Wilson (no. 15443), in a river thicket, San Pedro and vicinity, 
Isle of Pines, agrees perfectly with the type in characters of foliage and pubescence, 
but, in the absence of flowers or fruit, it does not seem advisable to refer it definitely 
‘ to this species. 
13. Homalium pedicellatum Spruce; Benth. Journ. Linn. Soc. Bot. 4: 36. 1860. 
Older branchlets fuscous brown, glabrate, the younger fuscous, griseous-puberulous 
and sparsely hispid-pilose with spreading hairs; leaf blades 7 to 11.8 cm. long, 2.5 
to 4.7 em. wide, oblong-elliptic or lance-elliptic, short-pointed, with an obtuse tip, 
rounded or sometimes cuneate at base, pergamentaceous, crenate-dentate with 10 
to 18 pairs of obtuse teeth, very shiny above, incurved-puberulous along costa and 
sometimes very sparsely on surface, beneath dull, barbellate in the axils, sparsely 
pilose along midrib, with 5 to 9 pairs of lateral veins; petioles rather sparsely pilose 
and puberulous, 8 to 12 mm. long; racemes axillary, loosely flowered, simple, griseous- 
puberulous with incurved hairs and sparsely pilose, the peduncle 3 to 3.5 cm. long, 
the rachis 9 to 15 cm. long; pedicels 1 to 6 mm. long; fruiting calyx tube turbinate, 
contracted into an obscure and very short pediform base, griseous-puberulous and 
sparsely pilose; calyx segments lanceolate, narrowed to an acutish or obtusish tip, 
griseous-puberulous outside and ciliate, nearly glabrous within below middle, 3.2 to 
3.5 mm. long, 0.8 to 1.1 mm. wide; corolla 1.2 to 1.4 cm. wide in fruit; petals ovate, 
narrowed from above the middle to an obtuse tip, griseous-puberulous on both sides 
and ciliate, 3.4 to 5 mm. long, 2.5 to 3.3 mm. wide; stamens in fascicles of 3 to 5, the 
filaments glabrous, shorter than petals; glands oval-oblong, griseous-puberulous, 
styles 3 or 4, glabrous or sparsely pilose at base, united into a sparsely pubescent 
column; ovary depressed-conic, densely griseous-villous.
