REMAKES.- Our fungus is closely related to the North American P. cohaesa, 

 with which it has many striking characters in common ; namely, the presence of 

 the uredospores and paraphyses. The general characters of teleutospores, 

 uredospores and paraphyses are almost exactly the same iu both plants. But in 

 our plant, the uredospores are found mixed in among teleutospores. The 

 teleutospores are very variable in size and their maximum sizes are considerably 

 larger in ours (50 x 35/i against 40 x 24/x). The macroscopical appearance of the 

 teleutosori of our specimens also differs somewhat from that of the American 

 specimens, the sori of our fungus being not confluent in large masses or not 

 formed in a ring. But as the essential characters of our Puccinia coincide 

 practically with those of the American, I have considered the Japanese plant as a 

 variety of the latter.
