Remarks. Dietel (3) described this si^ecies from the specimens col- 

 lected at the Tokyo Botanic Garden in iSijS by Prof. MlYOSHl, and he fully 

 discussed its distinctive features from Pucciuia EiilalicS, P. Polliniic and 

 /'. subnitciis. 



Urcdo Miscanthi v. Ilenn. ought to be referred to liere. P. Hennigs 

 gave, although it has not yet been published, the above name to a Uredo on 

 Spodiopogon cotuUfcr Hack. { = ]\Iiscaul/uis cotulifcr) which was sent him by 

 Mr. T. YosniNAGA. On examining the original specimen of Urcdo Mis- 

 canthi, I came to the conclusion that it is nothing but the lu'edostage of our 

 Piiccinia Miyoshiana.
