84 RYDBERG: NOTES ON ROSACEAE 
There are, in the collections examined, a few specimens from 
Nevada and the Klamath region of California which can not be 
referred to any of the species treated above. Some of these may 
be referred to R. Macounii, but the localities are out of the known 
range of that species. The rest may belong to two or three ap- 
parently undescribed species from the Columbia Valley and the 
Great Basin, but the limitations of these species are stiil unsettled.
