The present known range is from Maine west to Minnesota, south to 
West Virginia and Indiana. Collections from the following states have 
been examined by the writer and are represented by specimens in the 
herbarium of Dr. J. C. Arthur at Purdue University, where the writer 
has carried on the major part of his studies. The collectors’ names are 
included in parentheses. 
Delaware (Jackson). 
Indiana (Hunter). 
Maine (Arthur). 
Michigan (Arthur, Kern). 
New York (Webber, Reddick, Edgerton, Stone). 
Ontario (Arthur, Dearness). 
Pennsylvania (Swmstine). 
West Virginia (Sheldon). 
Wisconsin (Davis). 
During the year no additional facts have been brought out which 
throw any light on the specific standing of the timothy rust. The writer 
is still of the opinion that it is not entitled to specific rank and would in- 
clude it under Puccinia poculiformis (Jacq.) Wettst. (Pueccinia graminis 
Pers.) The statement made kist year could, perhaps, be somewhat modi- 
fied. Rather than calling it a race, physiological species or form species, 
it might be better to consider it a variety or subspecies since it does, as 
previously pointed out, possess some slight morphological differences from 
the typical form, particularly in the smaller secial cups and the more deli- 
eate uredinial mycelium.
