Discussion | Variety steenensis is endemic to the upper elevations of Steens Mountain in Harney County. It appears distinct when seen in its dwarfed form on the highest slopes; some transitional plants exist at lower elevations where it encounters var. pilosa. Genetic studies of this complex are in progress. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
