This very important wheat rust was first found in the United 
States, May 21, 1915, at Sacaton, Arizona, by Dr. F. K. Ravn, the 
eminent Danish cereal pathologist, who at that time was making a 
tour of investigation of cereal diseases in company with pathologists 
of the Department of Agriculture (Carleton, Science N. S. 42: 58. 
1916). A few weeks later the rust was found by Dr. Ravn and party 
at Medford and Corvallis and later was detected at Moro, Oregon. 
There is every evidence that this rust has been present in the western 
states for some years. Several collections reported above were made 
in 1914 but were confused with P. Clematidis. The writer is indebted 
to Dr. H. B. Humphrey for examining most of the collections and for 
the detection of several specimens belonging here, previously referred 
to other species.
