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.
