Camagüey), Dec. 2, 1915, Johnston 371; Marianao 
(Prov. Habana), Feb. 6, 1916, II, Johnston 443. 
The full life history of this rust is not known. No telia have 
been found in America, and no pycnia anywhere. It is cosmo- 
politan throughout the tropics, but in the West Indies is only re- 
corded from Cuba and Porto Rico.

This rust is still imperfectly known, as the pycnia have not 
been found. It is rather common upon wild and cultivated cot- 
tons in both hemispheres, but in the West Indies is reported only 
from Cuba and Porto Rico.

An imperfectly known species, the pycnia not having been 
seen. It is not an uncommon species in the southern United 
States, Central America, and parts of South America, but from 
the West Indies only one other collection is known, which was 
obtained by Whetzel & Olive in Porto Rico, on Malache scabra 
(Mycol. 9:63. 1917).
