7. Puccinia pertsnuis S. Itö n. sp. — (PL X. Fig. 9.) 
Teleutosori, hypophyllous, rarely epiphyllous ; minute, oblong or linear, 
densely scattered over the discolored portion, sometimes confluent, naked or 
loosely covered by the epidermis, pulvinate, compact, conspicuous, black. 
Uredospores mixed in the sori. 
Uredospores ellipsoidal to globose, echinulate, 16-24 x 16-18/*; epispore 
thin, light yellowish ; paraphyses short, obovate-clavate, light 'brownish-col- 
ored, apex not thickened, 30-55 X 20-26/*. 
Teleutospores cylindrical, linear or oblong clavate, apex thickened, 
coronate with numerous blunt somewhat long processes, base attenuated, 
scarcely constricted at the septum, ferruginous, darker at apex, 40-72 x 10- 
16/* ; epispore very thin ; pedicels brown, short, subdeciduous.

Remarks. This species resembles Puccinia coronata in the position 
and macroscopical appearance of their teleutosori, but they can easily be 
distinguished from each other microscopically. 
In the general lorm of the teleutospores, our plant resembles Puccinia 
Epigejos , from which it differs, however, in the position of its teleutosori and 
in the smaller size of its uredospores. 
8. Puccinia Hierochlose S. Itö n. sp. — (PI. X. Figs. 10, 11.) 
Uredosori, amphigenous, mostly epiphyllous, or on the sheath ; small 
oblong or linear, densely or loosely scattered over the surface, often con- 
fluent, naked or loosely covered by the epidermis, pulverulent, orange-col- 
ored. Uredospores ellipsoidal to globose, echinulate, 16-26.5 x 12-18/*; 
epispore comparatively thick, hyaline or yellowish ; paraphyses sometimes 
present, clavate or capitate, hyaline, apex not thickened, 50-72 x 10-15/*. 
Teleutosori, amphigenous, mostly epiphyllous or on the sheath ; small 
or medium in size, oblong or linear, scattered or gregarious, often confluent 
(2-4 mm.), loosely covered by the epidermis, becoming soon naked with 
ruptured remains, pulvinate, compact, conspicuous, black. Teleutospores 
cylindrical, oblong-clavate or linear-clavate, apex thickened, with the nu-
