ON THE UREDINEAE PARASITIC ON THE JAPANESE GRAMIXEAE. 1S7 



Remarks. The only species of Uromyces known to grow on JMiicli- 

 lenbergia is U. minimus Davis in North America. To that species, our plant 

 is closely related, but there are some points of difference between them, that 

 would warrant us to consider them as distinct species. The characteristic 

 by which our species can easily be recognized from the American, is the 

 entire absence of paraphyses in the teleutosorus of our plant.

Remarks. In 1892, Klebahn (i) remarked on the presence of two 

 kinds of coronate Puccinia ; wdiich had generally been regarded as a single 

 species under the name of Puccinia coronata. They are Puccinia coronata 

 and P. coronifcra (2) ( = P. Lolii Niels.). The former species is related to 

 the .(Ecidium on Rhamnus Frangula and the latter to the yEcidium on R. 

 cathartica. Eriksson and Klebahn by a long series of careful experiments 

 proved the presence of many specialized forms in both of these species. 



In our country, there are many species of coronate Puccinia ; but only 

 those oi Calavia^rostis arundinacca var. sciuroidcs and C. robusta, although
