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.) |
Varieties 2 (2 in the flora). Castilleja campestris is sometimes confused with Triphysaria eriantha subsp. eriantha, but C. campestris has two-celled anthers and entire leaves, while T. eriantha has one pollen sac per stamen and strongly divided leaves.
