It has seemed best to adopt for this plant the name above used 
in place of the name P. pubescens Gray, most unfortunately dragged 
forth from its herbarium obscurity by Chodat. P. pubescens Mart., 
not mentioned by Chodat, was described without locality in con- 
nection with three other new species of India, and as a MSS. syno- 
nym of Rottler’s is cited for this as for the other three species it is 
safe to assume that it also is an Indian species. Accordingly its 
confident identification with P. violacea Aubl. of Guiana by the 
Index Kewensis is clearly erroneous, as is confirmed by Martius’s 
description. In the lack of any definite disposition to synonymy 
of Martius’s species, it is certainly inadvisable to use the same 
name for the Mexican plant here described. This binomial (P.
