It was stated in the 1915 list that the specimen on which this record was 

 based (Lafayette. Tippecanoe Co., May 22, 1902. Wm. Stuart) was not 

 available and the determination was doubtful. The specimen has since been 

 located and deposited in the Arthur herbarium. It is found to be correctly 

 determined. An earlier collection, which was overlooked, was made at 

 Lafayette, July 11, 1900, by Wm. Stuart and distributed in Arthur & Hol- 

 way's Uredineae Exsiccati et Icones, No. 58a and 58d. 



Collections were also made by the writer in 1920 at two different points on 

 Wea Creek, south of Lafayette, on Sept. 15 and Oct. 23.

105. The rust on Potentilla canadensis L. so common throughout the state 

 and recorded as Knehneola ohtusa (Strauss) Arth. in the 1915 list has been 

 restudied and its affinities determined to be with Phragmidium rather than 

 Kuehneola. It is a brachy-Phragmidium and on this account, Dr. Arthur 

 has erected the genus Frommea (Bull. Torrey Club 44:503. 1917) to in- 

 clude this and one other species. The name is written Frommea obtusa 

 (Strauss) Arth. {Phraomidium TormentiUae Fckl.). European authors in 

 general do not consider the American species identical with the European. 

 Those who accept this view should write the name of the American species 

 Phragmidium triarticulatum (B. & C.) Farl. (Arcgma triarticulatum B. & 

 0.).
