which I think is the first collection made in Hokkaido. Me Alpine (i) re- 
marked, that the teleutospores of this species on Avena fatua in Australia 
are longer than those on Avena sativa, reaching 86//- in length. In our 
country, I have not been able to find any teleutospore on the former host- 
plant, although the uredospore-stage is found. On examining our specimens 
on Avena sativa , however, I noticed the dimension of the teleutospore is 
slightly longer than that of Europe, the maximum length reaching 72« in 
ours, while in European forms only 60//. In other respects, they thoroughly 
coincide with each other. 
The aecidial stage of this species as well as of Puccinia coronata is not 
yet found in Japan.

Remarks. Dietel (2) elevated the Barcley’s var. himalensis of 
Puccinia coronata to a distinct specific rank on account of the smaller size 
of aecidiospores (13-16 x 10-15//) and of naked teleutosori. 
In Japan, Prof. S. KUSANO collected this species for the first time on 
Brachypodiuni silvaticum in Prov. Izu, and Dietel identified it with the 
Himalayan species. In the present paper a new host-plant, Brachypodiuni 
japonicum , is added to the fungus. 
An yEcidium on Rl.amnus japonicus, sent to Dietel from our country 
was considered by him as a stage of Puccinia himalensis (7). But after- 
wards another yEcidium on Rhamnus japonicus was reported by the same
