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 heteranthus ranges from the Cascades in Oregon southward through the Sierra Nevada and eastward to Mono County, and disjunctly in the San Gabriel Mountains, in California, and is widespread over the western one-fourth of the intermountain region from Steens Mountain and eastern Lake County in Oregon eastward to Humboldt, Pershing, and Nye counties in Nevada. It grades in the northeast into var. utahensis and in the southeast into var. palmeri and var. argenteus in Idaho.

Variety heteranthus differs from var. utahensis by the more pronounced calyx spur and the more widely gaping flowers.
