Glycine lucida Blanco Fl. Filip. (1837) 578, non Forst., nec Grah.=Lablab 
cultratus DC.; Blanco op. cit. ed. 2 (1845) 405; ed. 3, 2 (1879) 379, 
t. 292—=DOLICHOS LABLAB Linn. 
Blanco correctly interpreted Lablab cultratus DC. in the 
second edition of his Flora de Filipinas. The species is com- 
monly cultivated throughout the Philippines and is frequently 
found growing wild, thoroughly established. It is not a native 
of the Archipelago, but was certainly purposely introduced in 
prehistoric times. It is very generally known in the Philippines 
as batao, a name of Chinese origin. Dolichos lablab Linn. is the 
type of the genus.

neously reduced by Fernandez-Villar to Phaseolus calcaratus 
Roxb.
