No other collections are known from Porto Rico, but it was 
found in Antigua on P. fimbricaturn, by J. N. Rose 3410. Dr. P. 
Sydow kindly sent me material from his herbarium representing

A collecion of the rust on P. pilosum Lam. was obtained by 
Dr. Stevens at Caracas, Venezuela. It is a rather common rust

and Earle, shows the two forms to be identical.
