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.

In China previously recorded from Chihli, Shingking, and 

 Shantung, but not previously reported from southern China. 

 The specimens cited above agree closely with material from 

 Chihli, differing chiefly in some of the leaves being broader 

 than in the northern form.
