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 schizotricha is a rare species restricted to high elevations in the mountains in Siskiyou and Trinity counties in northwestern California and in Jackson and western Klamath counties in southwestern Oregon. See the discussion of 6. C. arachnoidea for morphological differences between it and C. schizotricha, as the two are sometimes confused. Though their ranges overlap, they do not appear to hybridize.
