Distribution: Upper Sonoran and Transition zones of the 

 Sierra Nevada from Butte county southward. In southern Cal- 

 ifornia it is found through the Transition and Upper Sonoran 

 zones of the mountains and on the foothills and sandy plains as 

 far south as Riverside and Orange counties. Along the south- 

 ern border of its range, especially in the San Jacinto and Cuia- 

 maca mountains, intergradation between the typical form and 

 the variety becomes evident.
