Arth. from Muhlenbergia mexicana. On May 5 a few spermo¬ 
gonia appeared and a few days later the numerous clusters be¬ 
came very conspicuous. Hfcidia in fair numbers appeared May 
15. This experiment seemed from the first appearance of the 
spermogonia to be conclusive, yet it was deemed best to repeat 
it on a larger scale. Accordingly three thrifty large plants and 
two transplanted somewhat later and only pushing out the shoots 
half an inch, the leaves not yet unfolded, were carefully inoculated 
(Exp. No. 161) with teleutosporic material similar to that used 
in the first experiment. On May 13 the spermogonia appeared 
and at this writing all of the leaves of the five plants inoculated 
are highly colored with the myriads of spermogonia and secidia, 
and a few of them are partially aborted from the presence of the 
parasite. 
Cseoma ^Ecidium hibisciatum was described by Schweinitz 
in 1834 (Trans. Am. Phil. Soc. Philadelphia, 4:239). The Puc- 
cinia in question, rather common throughout Eastern United 
States, was called Puccinia windsorias and Puccinia dochmia. 
Dr. Arthur has shown that these two names apply to different 
species of Rusts—the former designating a Puccinia that be¬ 
longs to Tricuspis (Triodia), and the latter having as its host the 
species of Muhlenbergia. But he separated the Rust in question 
from Puccinia dochmia and proposed the name Puccinia 
muhlengergiae Arth., Bull. Lab- Nat. Hist. State Univ. Iowa, 
5:317. Oct. 1902. 
It therefore becomes necessary to make a new combination 
as shown in the following paragraph which also recapitulates the 
synonomy:
