The Rocky Mountain element consists of a considerable number of 

 species, including some genera which otherwise do not occur in 

 Washington or Oregon. Most of these are confined to the higher 

 granitic peaks, very fcAV occurring within Washington limits. The 

 presence of this Rocky Mountain element is undoubtedly a direct 

 result of immediate contiguity, though the species may have been 

 isohited on these remote peaks for a long j^eriod. It is noteworthy 

 that a number of the list reach the Sierra Nevada but not the Cas- 

 cades. The species are as follows :
