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 nelsonii is fairly common in the upper elevations of the so-called sky island ranges from central and eastern Arizona to adjacent New Mexico, southward into the Sierra Madre Occidental, at least as far south as southern Chihuahua, where the type collection was obtained on Cerro Mohinora. Although it was long known in the United States as C. austromontana, the name C. nelsonii has priority. Some specimens from southern Coconino County, Arizona, approach C. miniata, but most material is easily separable. Castilleja nelsonii occasionally hybridizes with C. mogollonica in Apache County, Arizona, near the border of the range of the former.
