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 haydenii is endemic to high-elevation slopes in the Rocky Mountains of southern Colorado and northern New Mexico. It is known in Utah from a single collection from high elevations in the La Sal Mountains. Reports of this species elsewhere are usually attributable to C. rhexiifolia. Its affinities are uncertain. Some features are shared with C. rhexiifolia, but in other ways it resembles species such as C. lemmonii of the Sierra Nevada. Plants in the northwestern portions of its range tend to have less divided leaves. Castilleja haydenii occasionally hybridizes with C. occidentalis where the two commingle in the lower alpine zone.
