fEcidiospores on Juula dysenterica, May to July. 
Teleutospores on /uncus obtusifiorus, July to October, and 
lasting through the winter on the dead stems. 
BIoLoGy.—The presence of the mycelium of the zcidiospores in 
the leaves causes round spots, which are yellowish in colour, and 
surrounded by a purple line. Fuckel suggested the probability of the 
connection between the ecidiospores and the teleutospores, but I 
believe the actual demonstration of their relationship by culture was 
never made until I did so in 1882. 
Uromyces pisi. (Pers.)
