petiolules 2 in. long densely pubescent, stipels slender subulate '2 in. 

 long, stipules lanceolate sparsely pubescent '3 in. long. Racemes dense 

 few-fld. at the end of sparsely pubescent peduncles 4 in. long, bracts 

 lanceolate densely pubescent '3 in. long, pedicels "1 in. Calyx '15 in. 

 long puberulous externally, teeth triangular except the lowest lanceolate 

 which is twice as long as the others and half as long as calyx-tube ; 

 bracteoles at base as long as bracts but rather narrower. Corolla bright 

 yellow '5 in. long glabrous. Pods ascending or almost erect, densely 

 clothed with spreading hairs, 1*5-2 in. long, *25 in. wide, compressed, 6-8 

 seeded. Seeds *15 in. long, '1 in. wide, dark brown, flat, oval, hilum one- 

 third as long as seed not very prominent, dissipiment between seeds not 

 pronounced. W. & A. Prodr. 245 ; Wall. Cat. 5889 in part only. P.

Pjiov. Wellesley ; at Prye Dock, Curtis 2211 ! Perak ; at Goping, 

 Kunstler 946 ! Distrib. Wild in S.-E. Asia and also largely cultivated. 



Very nearly related to P. suhlohatus Roxb. (P. trinervius Heyne) which differs 

 ia having narrower pods, more distinct dissepiments between the much smaller 

 seeds, and a rusty-red pubescence. This is the wild form of the plant cultivated in 

 India as the mdsh-kulai or urd crop; though it happens to have been named P. 

 Mungo by Linnaeus it is quite distinct from the Mung plant which has spreading pods 

 with smaller seeds and dark green leaves. The Mung is the species named P. 

 radiatus by Linnaeus.
