Discussion | 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.

Varieties 4 (4 in the flora). Castilleja parviflora is a complex, geographically widespread, and often misunderstood species ranging from southeastern Alaska through much of British Columbia, southwestern Yukon, and the Rocky Mountains of extreme western Alberta and southward in the Cascade Range to central Oregon.
