REMARKS. The present species differs from Puccinia Symphyti- 
Bromorwn Müll, on Bromus japonicus and B. pauciflorus on many points. 
The teleutospore of this species is sometimes provided at its obtusely 
pointed apex with a subhyaline flattened papilla-Üke protuberance which is 
often difficult to distinguish, while in Puccinia Symphyti-Bromorum, such a 
protuberance is entirely wanting. The size and general shape of the 
teleutospores are so conspicuously different in these two species, that I do not 
hesitate to consider our plant as a distinct new species. 
B. Paraphyses present in uredosori.
