78 RYDBERG: NOTES ON ROSACEAE 
This species is related to R. pisocarpa and R. ultramontana, 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. californica ultramontana 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.
