Discussion | Castilleja suksdorfii is endemic to wet habitats in the Cascade Range from the Goat Rocks Wilderness Area in Yakima County, Washington, south to the vicinity of Crater Lake National Park in Klamath County, Oregon. Reports of this species farther north in Washington and southern British Columbia are referable to C. rupicola. Castilleja suksdorfii is a polyploid species and may be of hybrid origin.

Castilleja christii is endemic to subalpine meadows near the summit of Mt. Harrison in the Albion Mountains, Cassia County. Morphologically, it most closely resembles the widespread C. hispida var. acuta, but a recent molecular study (D. L. Clay et al. 2012) presents clear evidence for a homoploid hybrid origin for the species, incorporating portions of the genomes of C. linariifolia and C. miniata. This is the first documented case of homoploid origin in Castilleja. Castilleja christii is in the Center for Plant Conservation’s National Collection of Endangered Plants.
