ON THE UREDINEAE PARASITIC ON THE JAPANKSE GRAMINEAE. 205 



All these relations remain unsettled so long as the infection experiments 

 are not carefully performed. Meanwhile, I am compelled to adopt the old 

 collective name o'i Piiccinia scssilis in this paper.

Remarks. Dietel (6) regarded this species to be a new one remarking 

 on the shortness of the teleutosori, on their arrangement in lines and on the 

 larger size of the uredospore. 



From the related species Puccinia hijna/cnsis, this fungus may easily be 

 distinguished by the absence of a crown at the apex of its teleutospore. 

 From Puccinia cnlniicola, it is distinguished at once by the naked sori of 

 the former. 



Dietel (6) describes the uredosori as hypophyllous, and the teleutosori 

 as epiphyllous ; but by examining the same type specimen, I observed that 

 uredosori are epiphyllous and the teleutosori are hypophyllous. 



19. Puccinia Bromi-japoiiicae S. Ito. n. sp. — (PI. XL F^ig. 4.) 

 Uredosori, epiphyllous ; minute, oblong or linear, scattered or gregarious, 



often confluent, j-ellowish brown. Uredospores globose, subglobose or 

 ellipsoidal, densely echinulate, yellowish, 22 — 30x18 — 25//; epispore thin ; 

 germ-pores numerous, inconspicuous ; paraphyses absent. 



Teleutosori, h}'pophyllou': or on the sheath ; small, oblong or linear, 

 scattered or gregarious, often confluent, always covered by the 

 epidermis, somewhat pulvmate, compact, conspicuous, blackish ; surrounded 

 by the thick bed of brown paraphyses. Teleutospores oblong-clavate, or 

 oblong, apex thickened (8—10/-/), obtusely pointed or rounded, rarely
