The species was united with C. Helianthi in the N. Amer. Flora 
(7 : 89. 1907), but the cultures by Hedgcock and Hunt^ indicate that 
it may be distinct, an assumption which is strengthened by the much 
more southern range, being common in Mexico, Central America and 
the West Indies, while the Coleosporium on Helianthus is not reported 
south of the United States. It was collected by Kellerman on V. 
gigantea Jacq., Patalul, Dept. Solola, Feb. 13, 1906, II, 5385, and on 
V. turbacensis H. B. K., Los Amates, Dept. Izabal, March 15, 1905,
