ON THE UREDINEAE PARASITIC ON THE JAPANESE GRAMINEAE. 
(Jredospores, ellipsoidal to globose, densely echinnlate, 16-22 x 15-18/i ; 
epispore thick (about 2 pi), yellowish or brownish-colored ; germ-pores 4, 
scattered. 
Teletitos pores, clavate or oblong- clavate, apex acutely conical or rounded, 
thickened (6-12 /a), rarely not thickened, slightly or markedly constricted 
at the septum, chestnut-brown, somewhat lighter colored at apex, 30-58 x 
16-22 fi] pedicels hyaline or subhyaline, as long as the spores or Sop in 
length, persistent. Mesospores occasionally mixed in the sori.

REMARKS. There are many species of Puccinia already known to be 
parasitic on Stipa. They are : — Puccinia graminella (Speg.) Diet, et Holw., 
P. graminella var. chilensis Neger., P. graminella var. Neesiana Speg., P. 
\Stipce (Opiz.) Arth., P. flavescens McAlp., P. Burnetti Griff., P. substerilis 
Ell. et Ev., and P. wolgensis Nawasch. Among them there are no species 
which are known to infect Stipa sibirica. The uredospores of this species 
s very small in size. Puccinia Stipcz approaches it in the point of smallness 
of the uredospore. But they differ from each other in the position of the 
teleutosori, and in the length' of the teleutospore and its pedicel. The length 
of teleutospore in ours is longer, while that of pedicel is considerably shorter. 
From other species, the present fungus differs so evidently that there is no 
need of stating the differences between them.
