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.

As delimited here, Castilleja lemmonii is endemic to the highlands of the Sierra Nevada in California and in adjacent Washoe County, Nevada. It differs from C. lassenensis, a plant of volcanic highlands around Mt. Lassen, which has consistently white corollas. Corollas are usually pink to purplish in C. lemmonii. Castilleja lemmonii also tends to have somewhat shorter lateral calyx clefts, though the two species overlap slightly in this character.
