Remarks. In 1892, Klebahn (i) proving its relation to the zEcidium 
on Rhamnus cathai'tica L. separated the present species from the old Puc- 
cinia corotiata Cda., under the name of Puccinia coronifcra (2). But 
Nielsen (i) in 1875 had already found a similar relation existing between 
the Alcidium on Rhamnus cathartica and the coronate Puccinia on Lolium 
perenne and he gave it the name of Puccinia Lolii, which should be adopted 
on account of its priority. 
Eriksson and Klebahn recorded six specialized forms to this species, 
and among them f. sp. Avence only has been found in our country. The 
uredospore-stage is common in our country, but the teleutospore-stage seldom 
occurs. Last fall I found the teleutostage on oats in the vicinity of Sapporo,
