A long slender climber reaching a height of from 12 to 15 in. with

 acuminate, without transverse plates and nearly glabrous, broadly winged 

 down both sutures. Petioles S to 10 cm. long, glabrous or very slightly 

 pubescent, the petiolules about ."> nun. long; leaflets ovate to elliptical 

 ovate, 10 to IS cm. long, (i to 11 cm. wide, abruptly caudate-acuminate. 

 the base rounded or subcordate, the terminal one regular, the lateral 

 ones inequilateral glabrous, or when young with few appresscd hairs; 

 stipels subulate, nearly 5 mm. long. Peduncles slender, 30 to 60 cm. 

 or more in length, the flowers paniculate at the apex, the branches 

 5 cm. long or less, the pedicels 1 to 1.5 cm. long, pubescent; bracts and

A species closely related to Mucuna gigantea DC. differing from that species 

 in its larger pods, which are without stinging hairs and which are rather long 

 apieulate-acuminate, rattier larger (lowers and leaves, the leaflets also differing 

 in shape and size. Differing from .1/. longi pedunculata Merr.. in its much smaller 

 Blowers.

Scandent, the trifoliate leaves '20 cm. long or less, the short peduncled 

 racemes 15 to tO cm. long, densely flowered, the flowers black-purple, 

 about 3.5 cm. long, the pods flattened, scarcely turgid, not plaited or 

 winged, straight, !' cm. long. L.5 cm. wide, densely covered with reddish- 

 brown pungent stinging hairs. Petioles 8 to in cm. long, pubescent, 

 the petiolules very densely pubescent, about 5 mm. long; terminal leaflet 

 broadly ovate, rounded-truncate at the base, the apex rounded, apiculate, 

 the lateral leaflets somewhat larger, 8 to !) cm. long, (i to S cm. wide,
