Sherfesee, Cenabre, & Cortez, April, 1914. On river banks and 
along the edges of secondary forests from sea level to an alti- 
tude of 200 meters; locally known in Samar as danipai. 
A remarkably distinct species characterized by its very long- 
peduncled infructescences and its elongated pods which are not 
transversely plicate, but very deeply and irregularly foveolate; 
the central foveolae are mostly rounded or angular in outline, 
the marginal ones more or less elongated transversely. The 
species is manifestly allied to Mucuna nigricans DC., but is at 
once distinguishable by its fruit characters.

A more or less woody vine, the younger parts more or less 
hirsute with appressed-cinereous hairs, the inflorescences cine- 
reous-pubescent and supplied with scattered, stiff, brown, 
stinging hairs, the branchlets nearly black when dry, about 2 
mm in diameter. Petioles 6 to 8 cm long; stipules narrowly 
lanceolate, about 8 mm long. Leaflets membranaceous, oblong-

the lateral ones distinctly inequilateral and rounded; stipels 
linear, 3mm long. Inflorescences up to 40 em long, the pedun- 
cles about 15 cm long, the branches few, 20 to 22 cmlong. Flow-
