P- 



2.2 cm. deep, rose-red, rarely yellow and violet; pod 10 to 12.5 cm. long, C to 8 mm. 

 wide, linear, compressed, slightly pubescent, dark; seeds 12 to 15. 



Near Bayamon on the roadside and in hedges; near Cabo Rojo, in thickets toward 

 Monte Grande; cultivated n<^ar ^fayaguez; near Afiasco, in thickets at Hatillo; near 

 Aguadilla, at Victoria.— Jamaica (Grisebach), Haiti, Guadeloupe, Martinique, St. 

 Vincent, Tol)ago. Cosmopolitan in the tropics. 



This plant is in its hal)iL quite different from P. semieredus, P. adenanthus is wide 

 climbing, the other erect, twining above. The pod of P. semierectus is very narrow 

 and subcylimlrical, that of P. adenanthu^ widely linear and compressed. The 

 flowers are largi^ than those of any other Porto Rican rhaseolus. In India the 

 tuberous root is cooked and eati^i, esi)(M*ially in time of faniine.
