ox TIIK UREDINEAE PARASITIC ON THE JAPANESE GRAMINEAE. 211 



blackish ; surrounded by the brown paraphyses. Teleutospores, cylindrical 

 or oblong-clavate, apex truncate or obliquely pointed, slightly thickened. 

 (4 — 8 ,«), base attenuated or angular, not or slightly constricted at the septum, 

 smooth, ferruginous, 44—58 x 15 — i//-«; epispore thin; pedicels short, 

 brown, subdeciduous.

Remarks. There are two species of Puccinia which have been known 

 to grow on Antlioxanthuvi. They are Puccinia Antlioxanthi Fuck, and P. 

 borealis IvittX. Puccinia Anthoxanthi oi Europe is distinguished macroscopi- 

 cally from the present species by its naked sorus. From Puccinia borealis of 

 America it differs in the form and size of the teleutospores. In P. borealis 

 the spore is clavate or subclavate, and smaller (35 — 45 x 13 — 20,«). 



This species approaches in its spore-shape to Puccinia dispersa. But 

 the attenuation of the lower cell of the teleutospore in this species is not so 

 abrupt as in the latter species. The general form of the spore is rather 

 cylindrical than oblong-clavate in our species. Its septum is located in a 

 lower position than that of/', dispersa. 



I have not yet seen any specimen of its uredostage, which I believe will 

 be found after a careful search. This fact makes the identification still more 

 difficult. At any rate, the points of difference from the related species, which 

 I ha\-e discussed, would justify us in considering this plant as a new species. 



b. Teleutosorus naked.
