106 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Type in the U. 8. National Herbarium, no. 679704, collected along the Camino 
del Boticario, near Chepo, Province of Panama, Panama, altitude 30 to 50 meters, 
October, 1911, by H. Pittier (no. 4544), 
Related to Morongia distachya (DC.) Cook & Collins, a species of southern Mexico, 
but differing in its numerous short, approximate pinne, which are leaflet-bearing 
nearly to the base, its pilose stems, and its smaller heads of flowers, these supported 
on shorter peduncles. 
NEW PANAMANIAN FABACEAE. 
During the study of the herbaceous representatives of this family 
collected in Panama by Mr. Pittier there have been discovered speci- 
mens of several South American species not hitherto known from 
North America. It is expected that an account of these will be 
published later. New species of several genera have also been 
detected, diagnoses of which are published here. 
Bradburya heteroneura Standley, sp. nov. 
Perennial vine with slender prostrate or climbing stems, these pubescent with short 
white slender hairs or glabrate; stipules lanceolate or lance-ovate, acuminate, 3 to 4 
mm. long, closely parallel-nerved, glabrous; petioles 6 to 25 mm. long, puberulent or 
soft-pubescent or glabrate; petiolules 1 to 1.5 mm. long; stipella: subulate, 2 to 3mm. 
long; leaves pinnately trifoliolate, the leaflets lanceolate to narrowly oblong-lanceolate, 
22 to 45 mm. long, 4 to 11 mm. wide, acute or obtuse, mucronulate, rounded or sub- 
cordate at the base, thick and somewhat coriaceous, bright green, scaberulous on the 
upper surface, glabrous beneath, the prominent veins much reticulated, 8 to 12 of 
the lateral ones much more conspicuous than the others, diverging from the midvein 
at an acute angle and anastomosing near the margin; peduncles short, axillary, 7mm. 
long or less, 1 or 2-flowered, white-villous; pedicels glabrous, about 7 mm. long, the 
bracts at their base 6 to 7 mm. long, broadly ovate, deeply cordate-clasping; bracts 
at the hase of the calyx ovate, inequilateral, 15 mm. long, acute, finely parallel-nerved, 
finely pubescent on the outer surface, twice as long as the calyx or more; calyx broadly 
campanulate, thin, pale, the upper lobes almost wanting, the margin appearing undu- 
late, the lower lobe linear, equaling or exceeding the tube, finely villous; flowers blue, 
the standard witha yellowish spet; standard 25 to 30 mm. long and of the same breadth, 
the upper edge nearly straight, finely soft-pubescent outside; keel and wings 15 to 
20 mm. long; young fruit linear, long-beaked, glabrous, the margins much thickened. 
Type in the U. S. National Herbarium, no. 678060, collected near Penonomé, 
Panama, February or March, 1908, by R. S. Williams (no. 328). 
This is most nearly related to Bradburya angustifolia. The venation of the leaves 
is very different in B. heteroneura and the bracts are pubescent instead of glabrous. 
Canavalia bicarinata Standley, sp. nov. 
Slender vine with purplish flowers; young stems finely tomentose with tawny hairs, 
the older ones glabrate; stipules small, linear-subulate, deciduous; petioles stout, 15 
to 55 mm. long, finely tomentose or in age glabrate; stipelle deciduous; petiolules 
3mm. long, densely pubescent with tawny hairs; leaflets ovate to ovate-oblong or 
elliptic-ovate, abruptly short-acuminate, the tip obtuse or emarginate, rounded to 
cordate at the base, dull green, thick and subcoriaceous, prominently veined, finely 
soft-pubescent on the upper surface, becoming glabrate, beneath sparingly pubescent 
with mostly appressed hairs; racemes 11 to 27 cm. long, rather slender, the rachises 
finely appressed-pubescent or glabrate, conspicuously nodulose, with numerous some- 
what remote flowers; bracts and bractlets much shorter than the calyx, broadly ovate, 
obtuse or acutish, conspicuously parallel-nerved, glabrous but ciliolate; pedicels very
