JACKSON: UREDINALES OF OREGON 261 



This short-cycled form possesses teUospores which closely resemble 

 the telia of the Carex rusts having aecia on Ribes (cf. P. Grossidariae, 

 109) as has been pointed out by Holway (N. Am. Ured. i : 53. 1906). 

 It is not to be confused with the rust having a similar life history 

 in the eastern United States, P. Ribis DC. The latter has verrucose 

 spores, while in the one under discussion the spores are smooth.

The above collections are referred somewhat doubtfully to this 

 species as no aecia have been collected in the Pacific northwest. 



The aecia occur on Onagraceae as was first shown by Kellerman 

 (1. c.) and later by Arthur (Bot. Gaz. 33: 13. 1903; Jour. Myc. 8: 52. 

 1902; 11: 58. 1905; 12: 15. 1906; 13: 195. 1907; Mycol. i: 233.
