530 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM, 
Type in the U. S. National Herbarium, no. 1,065,091, collected on hills of 
Guaremales, at La Fortaleza, along road from Puerto Cabello to San Felipe, 
Carabobo, Venezuela, altitude 400 meters, July 2, 1920, by H. Pittier (no. 8918). 
Related to Forsteronia gracilis (Benth.) Muell. Arg., the type collection of 
which has been examined. In that species the leaves are cordate at base, the 
main axis of the panicle is glabrous, and the corollas are 2 mm. long and 4 
mm. wide. FLorsteronia elachista has apparently the smallest flowers known 
in the genus. 
EXPLANATION OF PLaru 41.—Forsteronia elachista, from the type specimen. Natural 
size, 
ASCLEPIADACEAE. 
Prestonia brachypoda Blake, sp. nov. 
Scandent shrub; stem stout, densely hispidulous and more sparsely hispid 
with spreading or ascending, tubercular-based, rufidulous hairs: leaves opposite ; 
petioles 5 mm. long, pubescent like the stem; blades oval, 17.5 to 19.5 em. long, 
10.5 to 12.5 cm. wide, apiculate (the point 2 to 4 mm. long), at base cordate, 
pergamentaceous, above deep green, along costa and nerves hispid, on surface 
more sparsely so or glabrate, beneath brownish green with a slight yellow 
tinge, very densely and rather softly pilosulous with. spreading hairs, and along 
the veins sparsely hispid-pilose, the veins about 8 pairs, like the costa and 
secondaries impressed above, and with them finely prominulous-reticulate 
beneath; peduncle axillary, densely hispid-pilose with rufous hairs, 1.5 em. 
long; flowers numerous in a capitate cluster about 4 em. wide; pedicels densely 
hispidulous and hispid-pilose, 9 mm. long; sepals 5, oval, short-pointed, 11 mm. 
long, 5 to 6 mm. wide, rufidulous-hispidulous and hispid outside, each bearing 
at base within a deltoid scale 2.5 mm. long, truneate-and 4-denticulate at apex, 
densely strigose outside; corolla yellow, salver-shaped, the tube 16 mm. long, 
about 4 mm. thick, densely strigose with fulvous hairs, the limb 17 mm. wide, 
its lobes broadly oblong, strigose on one side without ; stamens inserted below 
apex of tube, barely exserted, the filaments 1.5 mm. long, densely ciliate, the 
anthers acuminate, 5.2 mm. long; corolla tube bearing below apex 5 linear 
truncate scales 3.2 mm. long, about twice as long as the depressed lobes of the. 
annulus, and with a hairy ring within just above the stamens; disk 5-lobed, 
equaling the scales of the calyx, surpassing the ovary. 
Type in the U, S. National Herbarium, no. 1,065,080, collected in forest at 
Guaremales, road from Puerto Cabello to San Felipe, Carabobo, Venezuela, 
altitude 10 to 100 meters, May 15, 1920, by H. Pittier (no. 8832), 
This species is nearly related to Prestonia surinamensis Muell. Arg., which 
is described as having the leaves obtuse at base and pubescent beneath with 
shorter flexuous hairs, petioles 1 em. long, and stamens inserted at about the 
middle of the tube. It is perhaps nearer to P. ipomaeifolia A. DC., which is 
described as having smaller and narrower leaves, acute calycine scales, calyx 
scarcely shorter than corolla tube, and corolla seales not longer than the corona. 
Fischeria subaequalis Blake, sp. noy. 
Scandent shrub; stem minutely hirtellous, more sparsely hispid with wide- 
spreading many-celled brown hairs; leaves opposite; petioles 3 to 4 em. long, 
densely hirtellous, rarely very sparsely hispid; blades oval or obovate-o ral, 9 
to 14 em, long, 5.8 to 8 cm. wide, apiculate (the tip about 2 mm. long), or rarely 
acute, at base cordate, the sinus usually concealed, papery or chartaceous, above 
dull green, densely hispidulous on both sides with spreading tuberculate-based 
hairs, the lateral nerves about 7 pairs, prominulous beneath, the secondaries 
scarcely prominulous; peduncles interaxillary, usually 11 to 15.5 em. long,
