Discussion

Castilleja lutescens is found east of the Cascade Range in Oregon and Washington and ranges east to western Montana and the adjacent interior of western Canada. Its inflorescences vary in color from entirely greenish to white or yellowish, and the stature of the plants is also variable, trending from moderate and compact in grasslands to taller in more forested situations. In the Blue Mountains of Garfield County, Washington, occasional hybrids form between C. lutescens and C. hispida var. acuta, which often both occur in the same vicinity.

L. R. Heckard (1968) reported a chromosome count of ca. 2n = 120 from a population in Montana.

Castilleja cinerea is endemic to the higher elevations of the San Bernardino Mountains, San Bernardino County. Most plants are upright to ascending and have yellow to yellow-orange inflorescences, with occasional plants ranging to dull red, especially with age. On Sugarloaf Mountain, mostly above 2700 m, is a distinctive form with consistently reddish purple to burgundy inflorescences and a strongly decumbent growth form.

Castilleja cinerea is most often associated with and likely parasitic on Artemisia nova and Eriogonum species. Castilleja cinerea is known from few populations and is threatened by livestock grazing, development, and vehicle use. It is listed as a threatened species under the Endangered Species Act of the United States.

The crystalline exudate associated with the stipitate-glandular pubescence of the distal portion of the bracts is unique in the genus.
