Stylosanthes sericeiceps Blake, sp. nov. 
Frutescent below, the glabrate grayish-barked stem 3 to 4 mm. thick, much 
branched, 30 em. long and more; branches herbaceous, slender, erect or ascend- 
ing, with many short branchlets, silky-pilose with erect hairs, these denser in 
lines; leaves shorter or longer than the internodes, 3-foliolate; sheath of the 
stipules densely silky-pilose, 5 to 7 mm. long, the stiff subulate-acicular teeth 
mucronate, 4 to 6 mm, lonz; petioles silky-pilosulous, 4 to 6 mm. long, the 
rtchis 1 to 2 mm. long; leaflets short-petiolulate, narrowly elliptic, 1.38 to 2. 
cm. long, 1.5 to 4 mm. wide, acuminate, mucronate, at base rounded, very 
sparsely pilosulous or nearly glabrous above, sparsely accumbent-pilosulous 
beneath, firm, the costa and 4 to 7 pairs of lateral veins impressed above, 
prominent beneath; spikes oblong or obovoid-oblong, approximate, about 1.5 
cm. long; primary bracts unifoliolate, the sheath 5 to 7 mm. long, densely 
silky-pilose-ciliate with whitish hairs and more sparsely silky-pilose dorsally, 
the teeth 4 to 5 mm, long, the blade lance-elliptic, 9 mm. long or less; sec- 
ondary bract 1, bifid, ciliate, 4 mm. long; axis rudiment present in the two 
lowest flowers of the spike, slender-subulate, stiff, densely pilose, 1 to 3.8 mm, 
long, absent in the other flowers; bractlet 1, similar to the secondary braet but 
nurrower and entire, of equal length; calyx 1 cm. long (including the stipe- 
like base, this 7 mm. long), the lobes ciliate; corolla yellow, the banner 8 mm. 
long; pod 6.5 to 7.5 mm. long, with both joints fertile, the lower obovoid- 
eblong, with incurved back, compressed, densely silky-pilose, 2-nerved on each 
side, 2.8 to 3.5 mm, long, 2 mm. wide, the upper joint similar but less densely 
pilose, 2.5 to 3 mm. long, 2 mm. wide, the incurved beak 1 to 1.2 mm. long. 
Type in the U. 8, National Herbarium, no. 1,069,160, collected at Lagunillas, 
Mérida, Venezuela, altitude 1,000 meters, October 6, 1921, by A. Jahn (no. 678). 
Closely related to Stylosanthes diarthra Blake, also of Venezuela, but en- 
tirely lacking the hispidity of that species, and with longer and comparatively 
narrower leaflets. 
Pterocarpus podocarpus Blake, sp. nov. 
Tree; branches glabrous, gray-barked; leaves alternate, 11 or 13-foliolate: 
petiole (2.2 to 4.5 em. long) and rachis (9 to 11 em. long) slender, pilosulous, 
glabrescent ; leaflets subopposite or the lower somewhat separated, petiolulate 
(petiolules 3 to 4 mm. long), the blades narrowly to broadly elliptic or some- 
what ovate-elliptic, 6 to 8 cm. long, 2 to 4.2 em. wide, obtuse to subtruneate or 
retuse, mucronate (mucro 1 mm. long), at the base rounded or cuneate-rounded, 
papery, above green, glabrous, beneath glaucesent, along costa and margin and 
sometimes along the chief veins rufous-pilose, glabrescent or glabrate, feather- 
veined (veins about 8 pairs, prominulous beneath, scarcely so above) ; racemes 
1 to 3, subterminal, 5 to 10 em. long, densely fuscous-pilosulous with ascending 
or erectish hairs; bracts and bractlets deciduous ; pedicels 5 to (fruit) 15 mm. 
long, bibracteolate near apex; calyx densely fuscous-pilosulous, 9 mm. long, the 
& teeth subequal, very short, obtuse: flowers yellow, the banner with a darker 
central spot ; banner suborbicular, the claw 3 mm. long, the lamina 11 mm. long 
und wide; lateral petals slightly longer than keel: staminal sheath split above; 
fruit obliquely ovate-suborbicular, 4.5 to 5.5 em. long, 4 to 5 em. wide, shortly 
falcate-tipped, at base truneate or subcordate, sparsely accumbent-pilose with 
rufescent hairs, 1 or 2-ribbed on sides, with chartaceo-coriaceous wing, reticu- 
late-veined, unarmed, narrowly decurrent on the upper part of the stipe, this 2 
em. long; seeds 2 (or sometimes 37), 
Type in the U. S. National Herbarium, no, 987734, collected in the vicinity of 
Las Trincheras, near Valencia, Carabobo, Venezuela, altitude 200 to 400 meters, 
December 30, 1917, by H. Pittier (no. 7636).
