 Sherfesee, Cenahre, & 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-dnereous hairs, the inflorescences cine- 

 reous-pubescent and supplied with scattered, stiff, brown, 

 stinging hairs, the branchlets nearly black when dry, about 2
