This species was formerly confused with P. canaliculata (Schw.) Lagerh., 
which has aecia occurring on Ambrosia and Xanthium. The Indiana speci- 
mens listed above were in part included with that species as No. 48 of the 
1915 list. Kern (Mycologia 11 :134-147. 1919) has recently pointed out the 
distinction between the two species. 
The aecidium of this species is unknown.

On POLEMONIUM REPTANS L. 
In a low flat woods on the south side of Half Moon Pond, about 10 miles 
southwest of Mt. Vernon, Posey Co., April 19, 1919, C. C. Deam 26992. 
A second collection was made by Mr. Deam in the same spot, Sept. 26, 
1920, (Deam 33050), 
This species, at the time the first collection listed above was made, was 
otherwise known only from the type collection made on P. caeruleum L. (P. 
occidentale Greene?), Kootenai Co., Idaho, J. H. Sandberg, July 1892. An- 
other collection has since been made on P. occidentale at Lake Tahoe, Cal- 
ifornia, Aug, 23, 1920, E. Bethel. The sori in the specimens collected by 
Deam occur on the petioles and leaf blades, often at the margin and are 
cinereous from the abundant germination of the teliospores. It is a lepto- 
Puccinia. No pycina were observed.
