xv, 3 Merrill: Notes on the Kwangtung Flora 243 
in Cochin China. His description applies unmistakably to the 
widely distributed and cultivated species currently known as 
Mucuna nivea Wight & Arn., and his specific name will replace 
that based on Roxburgh’s binomial. Loureiro’s description of 
the pods was apparently based on fresh rather than on dried 
material. Loureiro resided at Hue, and a mature pod secured 
from this locality under the local name cited by Loureiro, sub- 
mitted to me by Dr. A. Chevalier, is identical with Mucuna nivea 
Wight & Arn. Prof. C. V. Piper informs me that he examined 
Loureiro’s type in the herbarium of the British Museum in 1912, 
a leaf specimen only, making the note at that time that it might 
be any of the species allied to Mucuna nivea, but that it probably 
represented the latter species.

Chihli, differing chiefly in some of the leaves being broader 
than in the northern form.
