 plants, seeds from Panipanga Province, IjI/oh s. n. 



Native name: Sabual (Panipanga). 



^iessrsi. Piper and Tracy have recently studied tlie variovi.s cultivated forms of 

 Mucunfi, under the title '"The Florida Velvet liean and Related Plants" 1. c, and 

 have come to the conclusion that the Philippine Mucuna lyonii ^lerr., is identical 

 with the Indian .)/. nircum W. & A., or as they prefer to call it, ,Stizolohimn 

 nivenm (Roxb.) O. Ktze. They are undoubtedly correct in the above conclusion, 

 but I can not*concur with them in the opinion that "Mucuna nivca DC." which 

 is a nomen nudum, based on Carpopogon niveum Roxb. Hort. Beng. (1814) 54, 

 iiomen nudum, is a species distinct from Mucuna nivea W. & A. Under present 

 rules DeC'andolle's name, not being properly "published" has no standing. The 

 chief character by which Messrs. Piper & Tracy attempt to separate "Mucuna 

 nivea DC".," from M. nivea W. & A., is that the legumes, when ripe, are entirely 

 free from pubescence, a character expressly stated by Roxburgh in the original 

 description of his Carpopoyon niveum, Fl. Ind. 3 (18,32) 285, on wliicli Mncunu_ 

 nivea W. & A. was based.

Tlie origin of the above species is unknown, and its status is not detinitely 

 known. The two Philippine specimens were undoubtedly raised from American 

 seeds, the first from seeds distributed by the Philippine Bureau of Agriculture, 

 while the second appeared in nursery beds at Lamao. For a liistory of the 

 form see Bort, Katherine Stephens, "The Florida Velvet Bean and its History." '• 

 It is possible that the species is only a cultural form of Mucuna nivea, M. veluiina, 

 or some otlicr species.

Endemic. 



This last species can not be placed in its proper section until fruits are 

 secured; it is well characterized among the Philippine species by its ferruginous- 

 tomentose indumentum. 



The generic name Mucuna Adans. (17C3) has been retained in accordance 

 with the list of nomiiia conservanda of the Vienna Botanical Congress. Older 

 names are iitizolohium and Zoopthalmum, both of P. Browne (175G), and both 

 of these have been taken up by various later authors. The whole subject has 

 been well discussed by Prain," who treats both P. Browne's names as sub- 

 genera of Mucuna, but expresses the opinion that both Zoopthalmum and Sti~olo- 

 bium will probably at an early date be again considered generically distinct.
