226 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
late, acute, griseous-puberulous, 1.8 to 2.7 min. long, 1 mm. wide; petals ovate or 
thombic-ovate, obtuse, griseous-puberulous, 2.5 to 2.8 mm. long, 1.5 to 2 mm. wide; 
stamens in fascicles of 3 or 4, equaling the petals, the filaments glabrous; ovary 
short-conic, sparsely pilose; styles 3, long, united into a glabrous column nearly as 
long as ovary. 
Type in the U. 8. National Herbarium, no. 1,010,053, collected at ‘“B. J. Camp,” 
vicinity of San Juan del Norte (Greytown), Nicaragua, February 18, 1896, by C. L. 
Smith (no. 3). 
This species is closely related to H. guianense (Aubl.) Warb., but may be distin- 
guished by its much larger leaves which are spreading-pilose on the costa beneath, 
its sparsely pilose ovary, longer and glabrous style column, and longer styles.

Older branches grayish fuscous, at length glabrate; branchlets of the year densely 
griseous-puberulous and short-pilose; leaf blades 5.3 to 10 cm. long, 3.2 to 5 cm. wide, 
elliptic, oblong-elliptic, or obovate-elliptic, obtuse or short-pointed with blunt tip, 
cuneate to rounded at base, crenate with 10 to 22 blunt gland-tipped teeth on each

‘midrib, with incurved hairs, beneath densely griseous-puberulous with incurved 
hairs, barbellate in the axils of the veins; petioles densely griseous-puberulous and 
short-villous, 7 to 9 mm. long; peduncles short-villous and griseous-puberulous, 
axillary and subterminal, 1.8 to 2.5 cm. long; racemes simple, spikelike, loosely 
flowered, the rachis 4 to 5.5 cm. long; lower pedicels 0.8 mm. long, the upper obso- 
lete; corolla 11 mm. wide in fruit; fruiting calyx tube depressed-turbinate, without 
pediform base, 7 or 8-sulcate, puberulous like both sides of the limb; calyx segments 
7 or 8, ovate or lance-ovate, acute, 2 to 2.5 mm. long, 0.7 to 1.2 mm, wide; petals 7 or 8, 
ovate or broadly ovate, 3.2 to 4 mm. long, 2 to 2.5 mm. wide; stamens in fascicles of 
3 or 4, the filaments slightly hairy at base, shorter than the petals; glands oblate, 
puberulous; styles 3, distinct, glabrous; ovary depressed-conic, densely puberulous 
and short-villous. 
Tyre Locatity: Banks of the River Sururu, British Guiana. Type collected by 
Richard Schomburgk (no. 1463). 
SPECIMEN EXAMINED: 
Brazit: Without locality, Burchell 8203 (N). 
From H. mollicellum, which it most resembles, this species is distinguished by its 
subsessile flowers, smaller fascicles of stamens, and more depressed calyx tube. 
Although the type number of this species has not been available for examination, 
the specimens of Burchell 8203 in the National Herbarium agree so well with the 
description as to leave no doubt of their identity. The type number was referred by 
Bentham in his revision to H. racoubea (H. guianense), although that was described 
by him as possessing glabrous leaves. It is possible that the two species were dis- 
tributed by Schomburgk under his number 1463. 
5. Homalium mollicellum Blake, sp. nov. 
Older branchlets glabrate, lenticellate, grayish-barked; branchlets of the year 
brownish gray, puberulous with short spreading hairs, some longer spreading hairs 
intermixed; leaf blades 5.5 to 9.5 em. long, 3.2 to 3.8 cm. wide, elliptic or oblong- 
elliptic, short-pointed with blunt or emarginulate tip, rounded at base, shallowly 
repand-crenate with 11 to 16 blunt teeth on each side, chartaceous-pergamentaceous, 
with 9 to 12 pairs of lateral veins, above pale green, finely puberulous, glabrescent, 
beneath densely and softly cinerascent-pilosulous with spreading hairs; petioles 
tomentose-puberulous and villous, 5 to 8 mm. long; peduncles axillary and subter- 
minal, 2.5 to 3.8 cm. long; racemes nearly simple, puberulous and short-villous, rather 
loosely flowered, the rachis 7.3 to 9.5 cm. long; lower branches of the raceme (ped- 
uncles of the second order) 2 or 3-flowered, 2 to 8 mm. long; pedicels 0.8 to 2 mm. 
long; fruiting calyx tube turbinate, rounded at base, 6 or 7-sulcate, densely and canes- 
cently tomentose-puberulous like both faces of the limb; calyx segments 6 or 7, ovate,
