ON THE UREDINEAE PARASITIC ON THE JAPANESE GR AMINE AE. 1 87 
Remarks. The only species of Uromyces known to grow on Mneh - 
lenbergia is U. miniums 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 ; which had generally been regarded as a single 
species under the name of Puccinia coronata. They are Puccinia coronata 
and P. coronifera (2) (=P. Lolii Niels.). The former species is related to 
the Alcidium on Rhamnus Frangula and the latter to the Atcidium 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 of Calainagrostis arundinacea var. sciuroides and C . robusta, although
