Discussion

Variety fulvomaculatus is known from the Abajo and La Sal mountains in southeastern Utah, mountainous Colorado, in the Santa Fe National Forest and vicinity in New Mexico, and in northeastern Apache County, Arizona, where it is rare.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Variety montigenus is found along the eastern face of the Sierra Nevada from the Rock Creek Basin in Inyo County, California, to Washoe County, Nevada.

Variety montigenus can be differentiated by its long-petioled basal leaves at flowering, absence of a calyx spur, and open large flowers with banners that are hairy abaxially.
