absence of the crown, and from the other remaining species it differs by the 

 sorus long covered by epidermis. 



The shape of the teleutospores approaches nearest to that o{ Piiccinia 

 glumaj-uvi from which our plant can easily be distinguished b}' the uredosori 

 provided with numerous clavate paraphyses. This fungus is often found 

 mixed with Puccinia Moliniae on the same leaf of the host-plant. 



22. Puccinia Isliikawai S. Ito n. sp. — (PI. XL Fig. 5) 



Uredosori, amphigenous ; very minute, oblong, scattered, on the dis- 

 colored spots, often arranged in lines, sometimes confluent, loosely covered 

 by the epidermis or naked, somewhat pulvinate, orange-colored. Urcdo- 

 spores, globose or subglobose, rarely broadly ellipsoidal, finely echinulatc, 

 22 — 32x20 — 28,«; epispore hyaline or yellowish; paraphj'ses numerous, 

 clavate, membrane thickened, hyaline, apex not thickened, 40 — So X 1 1 — i6,m. 



Tclcutosori. hypophyllous ; very minute, oblong or linear, scattered or 

 subgregarious, arranged in lines, sometimes confluent, long covered by the 

 epidermis, somewhat pulvinate, grey or blackish. Teleutospores, clavate, 

 oblong-clavate or cuneatc, apex truncate, obliquely pointed or wavy, 

 thickened (4—6//), base mostly attenuated, not or slightly constricted at the 

 septum, rusty or light brown, darker colored at apex, 28 — 48 x 12 — 20/<, 

 rarely 22 « in width ; epispore thin ; pedicels short, brown, subdeciduous.

Remarks. The present species resembles closely ruccinia pygiiiaca 

 Eriks, in general characters. But they can easily be distinguished from 

 each other by the color of the pedicel of the teleutospore. \\\ Puccinia 

 pygviaca the pedical is hyaline, while in our species it is brown.
