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 still unsettled.
