Abundant about Manila, and thoroughly naturalized, apparently of compara- 

 tively recent introduction, as it is not described by Blanco, nor listed by 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 Roxb., 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 sjiecimens is 

 needed for purposes of comparison. The oldest valid specific iianio may prove to 

 be Phaseolus pubesrcns Biiinio.
