REMARKS. In 1898, SYDOW (t) described the uredostage of this fungus 
by the specimen of Arundinaria Fortunei var. aurea under the name of 
Uredo Arundinaria: . In 1900, DlETEL (3) gave the present name, describ- 
ing the teleutostage on Arundinaria Fortunei and A. Simoni. 
This species differs from Puccinia longicornis in the absence of para- 
physes in the uredosori and also in the shape of the apex of teleutospores. 
In regard to the latter character, however, the transitional forms are oc- 
casionally found between Puccinia Kusanoi and P. longicornis. I • found 
among the teleutospores of the present species some having even an apex 
18/t thick; while on the other hand, among Puccinia longicornis there are 
some only 8 p thick at the apex. 
The present species is more common in Japan than the other species of 
Puccinia growing on Bambuseae and the number of its host-plants are also 
more numerous.

Remarks. Prof. Kusano (3) described this variety of Puccinia Kusanoi , 
distinguishing it from the typical form by the longer teleutospores and by 
the presence of less constriction at septum. With the exception of the shape
