lected May 16, 1899, and has been repeatedly collected there, especially from 
1902 to 1908, by different people. About 12 different collections are depos- 
ited in the Arthur herbarium from this locality. During the past 12 years, 
however, no collections haye been made, though it has been repeatedly 
searched for, and we have feared that the species was extinct in this 
locality. It was, therefore, with considerable interest that the writer 
made collections of this rust on July 5 and Sept. 2, 1920 in a small swamp 
about one-half mile northeast of Dayton in Tippecanoe Co.
