Discussion | Castilleja lineariloba is endemic to the western slope of the Sierra Nevada. Its chromosome number is 2n = 20, an apparent aneuploid reduction and documented by numerous counts. This diploid number is shared only with two very distantly related annual species endemic to central Mexico, C. gracilis Bentham and C. tenuifolia M. Martens & Galeotti.

Castilleja schizotricha is a rare species restricted to high elevations in the mountains in Siskiyou and Trinity counties in northwestern California and in Jackson and western Klamath counties in southwestern Oregon. See the discussion of 6. C. arachnoidea for morphological differences between it and C. schizotricha, as the two are sometimes confused. Though their ranges overlap, they do not appear to hybridize.
