Cultivated throughout the Tropics, the native country not clearly known.—The 
allied P. tetragonolobus, DC., which has more slender stems, bracteoles shorter than 
the calyx, and a 12-16-seeded pod sometimes a foot long, is also widely cultivated. 
We have it from Mauritius, but not from the mainland within the Tropics.

Calyx campanulate, the upper teeth usually connate, the others nearly

usually rostrate, not spiral. Upper stamen free, often appendiculate or 
Incrassated near the base ; anthers uniform. Ovary subsessile, o-ovu- 
late ; style flattened upwards or filiform, longitudinally bearded near or

compressed, two-valved, the sutures incrassated, the valves nearly flat
