PUCCINI A HIBISCIATA (Schw.) Kellerm. from MUHLEN- 
BERGIA MEXICANA (L.) Trim, M. DIFFUSA 
•Willd., and M. RACEMOSA (Mx.) B. S. P. 
The connection established between the teleutosporic stage 
of this Rust — originally called Puccinia windsorise but latterly 
designated by Arthur and Holway as P. muhlenbergise — and 
the Aecidium hibisciatum Schw. occurring on Hibiscus moscheu- 
tos, was published immediately on the conclusion of two sets of 
satisfactory experiments. See Jour. Mycol. 9:109-110, May 
1903. But the report there printed does not cover the entire 
work with the species in question — dealing as may be recalled 
only with the Rust from one species only of Muhlenbergia, and 
with one species only of Hibiscus as the aecidial host. 
It is to be added that with similar care and well grounded 
hopes of success, inoculations were attempted with teleutospores 
from Muhlenbergia diffusa Willd. This had been collected No¬ 
vember 1, 1902, the same day on which the Muhlenbergia mexi- 
cana was obtained, and kept exposed all winter in suitable sacks 
by the side of the latter. Muhlenbergia mexicana was collected 
on the north shore of Buckeye Lake, Licking Co., Ohio, and M. 
diffusa was taken a mile distant where (on the south side of the 
lake) it was common though not abundant. 
Aecidium hibisciatum has been for years occurring in great 
abundance on Hibiscus moscheutos at both of the places just 
mentioned. No infections were secured, the host plants used
