ON THE UREDINEAE PARASITIC ON TIIE JAPANESE GRAMINEAE. 2 \y 
On Agropyrmn semicostatum Nees ? 
Honshu. — Prov. Rikuchü : Morioka (III. Nov. 12, 1905. G. Yamada). 
Distrib. Japan. 
Remarks. Dietel (9) described this species from the specimen col- 
lected by Prof. S. Kusano in Tokyo. It differs from other Puccinia on 
Br achy podium by the naked teleutosori and non-coronate teleutospores and 
by the invariable occurrence of the sori on the culm. 
I have found among the specimens sent to me from Prof. G. Yam ADA, a 
species of Puccinia on Agropyrum semicostatum? which coincides closely with 
the type specimen of this species on Brachypodium. 
30. Puccinia stichosora Diet., in Engl., Bot. Jahrb., 37, 1906, (100). 
Hab. On Calamagrostis arundinacea Roth. var. sciuroides Hack. 
Honshu. — Prov. Musashi: Tokyo (II. Sept. 15, 1904. N. Nambu). 
Distrib. Japan. 
REMARKS. By the kindness of Mr. N. NAMBU, I have been able to 
examine the type specimen of this species in its uredostage. The uredospores 
of this species differ from those on Calamagrostis by the darker color of 
their epispore.

REMARKS. No account concerning the occurrence of this species in our 
country, except a short note by Prof. S. KUSANO (2), has yet been published. 
In 1899, P- Magnus (2) remarked that there are two kinds of uredo- 
spores in this species. One kind has a thin echinulate wall with numerous 
germ-pores (to 9) located at the upper portion of the spore. Another kind
