Most of the above collections were made in connection with a national 
investigation of overwintering of stem rust. No overwintering of uredin- 
iospores was found to occur in Indiana during 1919. 
In the 1915 report only a single collection of the aecidium of this species 
on Berberis vulgaris was recorded. In connection with the barberry eradi- 
eation campaign for the control of stem rust, which is being conducted co- 
operatively between Purdue University and the U. 8S. Dept. of Agriculture, a 
large number of collections and observations have been made showing that 
this aecidium may develop in abundance on the barberry in all parts of 
the state. Specimens collected in 1918 and 1919 are now preserved in the 
Arthur herbarium from the following counties in Indiana: Allen, Franklin, 
Henry, Jay, Lagrange, Laporte, Noble, St. Joseph, Vanderburgh, Wabash 
and Wayne.

This was previously recorded as Dicaeoma Saniculae (Grev.) Kuntze 
(Puccinia Saniculae Grey.) and has been commonly referred to that species 
by American authors. P. Saniculae, however; is not an American species. 
Collections have been made on NSanicula canadensis l.? in Montgomery
