232 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
The species was originally described from “North Brazil and Venezuela, on the 
upper Rio Negro abundantly, Spruce, nos. 1489 and 3722.’’ Of these numbers the 
former is here selected as the type. The species has also been recorded by Eichler 
from Caracas. The stamens, according to Bentham and as shown in Eichler’s figure, 
are sometimes as many as five in a fascicle. 
14. Homalium eleutherostylum Blake, sp. nov. 
Branchlets fuscous, subterete, in youth finely puberulous with incurved hairs and 
rather densely pilose with dull wide-spreading hairs 0.5 to 0.8 mm. long, in age gla- 
brescent; leaf blades 8.2 to 14.2 cm. long, 3.3 to 5.3 cm. wide, oblong-ovate or oblong= 
elliptic, short-acuminate, with obtuse tip, rounded at base, chartaceous, crenate with 
15 to 18 pairs of very depressed rounded teeth, above more or less shining, along costa 
and the 7 to 10 pairs of veins finely incurved-puberulous, elsewhere very sparsely so 
or subglabrous, and along costa rather sparsely spreading-pilose, beneath dull, along 
costa (especially toward base) spreading-pilose, along the main nerves pilosulous, 
barbellate in the axils, elsewhere glabrous; petioles rather densely incurved-puberulous 
and spreading-pilose, 5 to 7 mm, long; peduncles axillary and terminal, solitary, 
pubescent like the stem, 3.5 cm, long; rachis incurved-puberulous and rather sparsely 
pilosulous, 7.5 to 9.7 cm. long; inflorescences simply racemose, cylindric, sparsely 
flowered; pedicels 1.5 to 5.5 mm. long; calyx tube in fruit turbinate-campanulate, 
without distinct pediform base, obscurely sulcate, rather sparsely griseous-puberulous 
with incurved hairs; calyx segments 5 or 6, lanceolate to lance-ovate, acuminate, 
griseous-puberulous, 2.5 to 3.5 mm. long, | to 1.3 mm. wide; corolla in fruit 11 to 12.5 
mm. wide; petals triangular-ovate or rhombic-ovate, obtusish, griseous-puberulous, 
3.8 to 4.3 mm. long, 3 to 3.38 mm. wide; stamens in fascicles of 3 or 4, glabrous, about 
equaling the petals; glands oval-oblong, griseous; styles 3, distinct, slightly pubescent 
at base, spreading in fruit; ovary depressed-conic, griseous-villous. 
Type in the Gray Herbarium, collected near Barra, Province of Rio Negro, Brazil, 
July, 1851, by R. Spruce (no. 1662). 
The type, distributed as “‘ Homalium pedicellatum var.,’’ is so similar in most respects 
to H. pedicellatum that I was for some time inclined to refer it to that species. It 
differs, however, not only in the free styles but in the denser pubescence of the branches 
and in the fact that the less shiny leaves are pilose above along the costa. 
15. Homalium hondurense Donn. Smith, Bot. Gaz. 20: 4. 1895. 
Tree, about 10 meters high; branchlets slender, gray, lenticellate; leaf blades 11.5 
to 16.5 cm. long, 5.5 to 8.7 em. wide, oval or broadly obovate-oval, short-pointed, with 
acutish tip, at base cuneate or rarely rounded-cuneate, thin, papery-membranaceous, 
coarsely undulate-crenate with about 12 pairs of rounded depressed teeth, above very 
sparsely strigillose along costa or essentially glabrous, beneath sparsely barbellate in 
the axils of the 7 to 9 pairs of prominulous-reticulate veins, otherwise glabrous; petioles 
essentially glabrous, 5 to 6 mm. long; peduncles axillary and terminal, solitary, 
glabrous, 3 to 6 cm. long; inflorescences conic-cylindric, paniculate to about the 
middle, then simply racemose; rachis puberulous with incurved-spreading hairs, 9 to 
13.5 cm. long; lowest branches of panicle 1 to 2.5 cm. long, few-flowered; pedicels 1.5 
to7 mm. long, puberulous; fruiting calyx tube turbinate, finely incurved-puberulous, 
obscurely sulcate, gradually or abruptly contracted into a pediform base about half as 
long as the body; calyx segments 5 to 7, linear-oblong or narrowly elliptic-oblong, 
obtusish, griseous-puberulous, 2.2 to3 mm. long, 0.5 to 0.8 mm. wide; corolla 11 to 18 
mm. wide in fruit; petals 5 to 7, ovate, oval-ovate, or rhombic-ovate, obtuse, somewhat 
contracted below the middle, griseous-puberulous, 4.3 to 4.8 mm. long, 2 to 3 mm. 
wide; stamens in fascicles of 3, shorter than the petals, the filaments glabrous; glands 
oval-oblong, sulcate, griseous; styles 3, distinct, hairy at base; ovary conic, shortly 
griseous-villous.
