ON THE UREDINEAE PARASITIC ON THE JAPANESE GRAMINEAE. 221 
On Miscanthus sp. 
Honshu. — Prov. Mutsu : Goshogawara (III. Oct. 1904. T. Kashiwai). 
Distrib. Japan and India. 
Remarks. Barclay (3) tells nothing of the uredosori of this fungus ; 
and his descriptions of the uredospores are made from those mixed in the 
teleutosori. Uredosori of this species are hypophyllous, small, roundish, 
oblong or linear in form, scattered or subgregarious on a characteristic dark 
reddish spot, often confluent (6 mm in length), naked, with torn epidermis 
on their margins, pulverulent, and brown in color. 
According to DlETEL (7), this fungus grows also on the leaves of Im- 
perata arundinacea, in which case the uredospores are said to be slightly 
smaller than those on Miscanthus sinensis. I have not been able so far to 
find the present species on hnperata arundinacea. Besides these two host- 
plants, two other species are added in this paper, namely Miscanthus 
sacchariflorus and M. condensatus.

Remarks, I have not able to find any uredosorus of this fungus 
in Hokkaido. SYDOW (2) also remarks that the uredosori are very scarce in 
Europe, as the uredospores are soon replaced by the teleutospors, converting 
them into teleutosori. 
The teleutospores of this species resemble somewhat those of Puccinia 
Phragmitis , but they are generally shorter in length and broader in width 
than those of the latter. These two species can readily be distinguished 
*rom each other by their uredospores. The uredospores of Puccinia Moliniae
