Discussion | 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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Castilleja pulchella is a mostly alpine species of the mountains of western Montana and adjacent Idaho and northwestern Wyoming, as well as in the Uinta Mountains of northeastern Utah. It is similar to and likely shares ancestry with C. chrysantha of the mountains of northeastern Oregon. Castilleja pulchella is variable in color, with inflorescences ranging from pale yellow to purplish, often within the same population. Some lower elevation populations are known. These plants are considerably taller, and they tend to have only yellowish inflorescences. Where the two occur together, C. pulchella occasionally forms hybrids with C. nivea.
