Castilleja rupicola
Castilleja cinerea
Castilleja rupicola is usually found in the subalpine and lower alpine zones in the Cascade Range from extreme southern British Columbia south to northern Douglas County, Oregon. Though it can be numerous where it occurs, the species as a whole is uncommon. One atypical population occurs in a moist, shaded, mossy, north-facing ravine on the Oregon side of the Columbia River Gorge, at less than 250 m. These plants often bear secondary divisions on deeply dissected leaves and bracts.

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.
