ON THE UEEDINE AE PARASITIC ON THE JAPANESE GRAMINEAE. 1 8 1 
climate has also been studied by many scholars. Moreover, the question of 
the propagation of the rust fungi has been fully discussed by ERIKSSON, 
Marshall Ward, Klebahn and other botanists. 
In our country, very little has as yet been done in regard to the investiga- 
tions of the biological characters as well as of the preventive means of the 
rust fungi. But to carry out such investigations satisfactorily, the classification 
based on careful morphological studies must first be undertaken. 
Messers. Y. Takahashi (i)(2) and A. Mabe (i) made some systematic 
studies of the rust fungi of our cereals. Mr. S. HORI ( i)(2) published the 
result of his study on Puccinia corticioides Berk, et Br., Mr. K. YOSHINO(i) 
on the rust of Setaria italica Beauv. var. germanica Trin., and recently Prof. 
S. KUSANO ( 2 ) published a monogragh of Puccinia on the leaves of 
Bambuseae, in which he described two new species, Puccinia Phyllostachydis 
and Puccinia Sasae, and a new variety, Puccinia Kusanoi Diet. var. Azmna. 
Besides those works, there are none yet published in our country relating to 
the Uredineae on Gramineae. Most of our species were identified and des- 
cribed by European mycologists — Berkeley, Dietel, Sydow, P. Hennings 
and Magnus. 
A large number of the specimens of the Uredineae on the Japanese 
grasses preserved in the Herbarium of our University were kindly placed in 
my hand by Prof. K. Miyabe for the preparation of the present paper. 
Besides them, many interesting and valuable specimens were kindly sent at 
my request by Profs. M. SHIRAT, S. KUSANO and G. Yamada, Messers. Y. 
Takahashi, A. Ideta, T. Nishida, T. Kawakami, J. Hanzawa, T. Mi- 
yake, R. Suzuki, M. Miura, M. Kasai, N. Nambu, K. Yoshino, T. 
Yoshinaga and T. Kuriiiara. All these specimens are now preserved in 
our University Herbarium. 
The specimens have been collected from different parts of Japan, from 
Saghalien and Kurile Islands on the north, to Formosa on the south. The 
total number of specimens I have examined is about 800, in which six genera, 
73 species and 2 varieties are included. They are as follows : — 
Uromyces 4 sps., and 1 var., Puccinia 58 sps., and 1 var., Diorchidium 1 sps., 
Stereostratum 1 sps., Rostrupia 2 sps., and Uredo 7 sps.
