The types of Mucuna sericophylla and M. luzoniensis are not identical, but 
additional material shows a number of intergrades, and I am now of the opinion 
that the species can not be distinguished from one another. The species shows 
some variation, but in all essential characters appears to be constant; the leaflets 
are not all emarginate, but frequently are blunt or acute, or even shortly apiculate- 
acuminate. It is manifestly allied to M. pruriens. 
Endemic.
