Abundant about Manila, and thoroughly naturalized, apparently of compara- 
tively recent introduction, as it is not described by Blanco, nor listed b.y F.-Villar, 
as is also the case with the preceding species. A native of tropical America, 
now widely distributed in the Tropics of the world.

I am not at all sure that all the specimens cited above really represent 
Phaseolus calcaratus Eoxb., but the description applies rather closely. Some 
of the specimens have been identified and distributed as P. mungo Linn., and 
others as Vigna luteola Baker. A good series of Indo-Malayan specimens is 
needed for purposes of comparison. The oldest valid specific name may prove to 
be Phaseolus pubescens Blume.
