Discussion | Castilleja xanthotricha is endemic to moderate elevations in the sagebrush hills of the John Day River drainage in north-central Oregon. N. H. Holmgren (1971) hypothesized that this tetraploid species is of allopolyploid hybrid origin between C. glandulifera and C. oresbia.

Castilleja cervina is found across northern Washington, from the eastern slope of the Cascade Range, east to northern Idaho and north to southern British Columbia. Plants at higher elevations are dwarfed. Reports from Montana need verification. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
