78 Rydberg: Notes on Rosaceae 



This species is related to R. pisocarpa and R. uUramontana, but 

 differs from both in the large, thin, broadly oval leaflets and the 

 few slender prickles. It is almost unarmed except on the new 

 shoots. From R. pisocarpa it also differs in the non-glandular 

 sepals.

1904 



This was first described as R. calif arnica uUramofitana S. Wats.,* 

 but is not at all related to that species. It is closely related to 

 R. pisocarpa and distinguished from that mainly by the sepals 

 which are not at all glandular. It belongs to the Great Basin, is 

 rather common in Nevada as well as Idaho and eastern Oregon, 

 but not so common in California. The following specimens have 

 been seen.
