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 rubricaulis ranges from British Columbia to Montana, southward into northeastern Nevada, the Uinta and Wasatch mountains in Utah, Apache and Coconino counties in Arizona, and western Colorado. It is very similar to var. argenteus but found in more moist or mesic habitats.
