A common and conspicuous rust, which is probably hetero- 
ecious. Other Porto Rican collections are on the same host ; 
they are without locality. Geo. P. Goll 436, 1899, Underwood & 
Griggs 26, 1901, from near Santurce, A. A. Heller 1296, 1899, 
from Mayagiiez, G. P. Clinton 72, 1904, from San Juan, E. W. 
D. Holway, 1911, and from Rio Piedras, H. B. Cowgill 303, 1912. 
It has also been collected in Jamaica, Dec., 1890, by A. S. Hitch- 
cock, and in Cuba, March, 1903, by E. W. D. Holway. 
The type material of A. solaniphilum examined, kindly sup- 
plied by Dr. Spegazzini, resembles the other specimens in gross 
appearance of both fungus and host. The microscopic characters 
also agree, except that the peridial cells seem somewhat smaller 
and more delicate.
