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.

Castilleja lassenensis is restricted to the Mt. Lassen area in Shasta and Tehama counties. See the discussion of 55. C. lemmonii for information on the relationship between these two species.
