ON TIIK UREDINEAE PARASITIC ON THE JAPANESE GRAMINEAE. 2 15 



Remarks. Busse (i. 2.) described this species most fully in his 

 papers on sorghum-rust in German East Africa, and supplemented thereby 

 the incomplete description of CoOKE (i). 



The host-plants of this species hitherto known are Ajidropogon Sor- 

 ghiiiii, A. Halcpensis, Zea Mays and Pcnnisetwn typhoidetmi. The occur- 

 rence of this rust fungus on the first mentioned host-plant in our country, 

 P. Hennings (i) asserts by examining the specimen collected in Tokyo, but 

 DiETEL (8) is of opinion that Pitccinia purpurea of P. Hennings may not be 

 different from his Pitccinia Nakanishikii.

Re.\i.-\RKS. Dietel (9) regarded this species as a new one, separating 

 it from Pucciuia Arundinellae Barcl., by its slender teleutospores. He based 

 this determination on the specimen collected by Prof. S. KusANO in Tokyo 

 in 1904. 



Previous to this period DiETEL (6) identified the specimen on the same 

 host-plant collected by Prof S. KuSANO in 1899 at Mt. Myogi, Prov. Kozuke, 

 to be Pucciuia graminis. 



In 1902, P. Hennings (3) also noticed the occurrence of Puccinia 

 grauiinis on Arjindinclla anomala, which was collected by Mr. T. YOSHI- 

 NAGA in icoi, at Akatouchi-toge, Prov. Tosa. 



Thus according to the European authorities, there seem to exist two
