Remarks. The present species differs from Pnccinia Sympliyti- 

 Broinorum Müll, on Bromus japonicus and B. paucißonis on many points. 



The teleutospore of this species is sometimes provided at its obtusely 

 pointed apex with a subhyaline flattened papilla-Hke protuberance which is 

 often difficult to distinguish, while in Pnccinia Syvtpliyti-Brouwruui, SLich a 

 ' protuberance is entirely wanting. The size and general shape of the 

 teleutosporcs arc so conspicuously different in these two species, that I do not 

 hesitate to consider our plant as a distinct new species.
