Discussion
Variety pilosa is found in sagebrush steppes and communities in the surrounding mountains from northeastern California through much of eastern Oregon, and northwestern Nevada. The inflorescences are almost always pale yellowish white when young and often turn dull reddish purple with age, especially proximally. This variety is sometimes confused with the high-elevation species Castilleja nana; it can usually be distinguished by the absence of blackish patches on the sides of the corolla tube, which are present in C. nana.
