Remarks. In 1S9S, S\T)0\V (i) tlcscribed the ui-cdostage of this fungus 

 by the specimen of Arundinaria Fort unci var. aurca under the name of 

 Urcdo Ariindinariic. In 1900, DiETEI. (3) gave tlie present name, describ- 

 ing the teleutostage on Arundinaria Fortnnci 'awX A. Siinoni. 



This species differs from Puccinia longicornis in tlie absence of para- 

 physes in the uredosori and also in the shape of the ape.x 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,« thick ; while on the other hand, among Puccinia longicornis there are 

 some only S/^ thick at the ape.x. 



The present species is more common in Jai)an than the other species of 

 Puccinia growing on Bambusea: and the number of its host-plants are also 

 more numerous.

Remarks. Prof. Kusano (3) described this variety oi 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
