JACKSON: UREDINALES OF OREGON 261 
This short-cycled form possesses teliospores which closely resemble 
the telia of the Carex rusts having aecia on Ribes (cf. P. Grossulariae, 
109) as has been pointed out by Holway (N. Am. Ured. 1: 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.
