New Species of Uredineae — I 



- 



By J. C. Arthur 



In the examination of material sent by various collectors for 

 identification, and of other material that has been in the author's 

 herbarium for a time, some forms of Uredineae have come to light 

 that seem worthy of description as new species. The collections 

 were made at various localities in the United States west of the 

 Mississippi river. The type specimen is in each case preserved in 

 the author's herbarium, but other specimens of the type collection, 

 which may be identified by data attached, especially by time of col- 

 lection, have been freely distributed as far as material permitted.
