Discussion | 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.

Although the range of Castilleja citrina overlaps the range of its close relatives, C. lindheimeri and C. purpurea, in central Texas, C. citrina extends considerably farther to the west and northwest of the others (G. L. Nesom and J. M. Egger 2014). The inflorescences of C. citrina are mostly pale to bright lemon yellow or occasionally brassy yellow. The color and usually more elongate abaxial corolla lip separate it from C. lindheimeri and C. purpurea. Castilleja citrina is similar to some color forms of C. sessiliflora, but the more conspicuously curved corolla of C. sessiliflora is usually exserted far above the calyx and is often white to pale pink, rather than yellow.
