Discussion | Varieties 3 (3 in the flora). Much confusion exists concerning Castilleja angustifolia and the closely related C. chromosa. Sometimes C. chromosa is treated as a variety of C. angustifolia, using the name C. angustifolia var. dubia. The latter name is used here to represent a different assemblage of plants, not including C. chromosa. At other times, C. chromosa is synonymized completely under C. angustifolia. However, the two species are in most cases easily separable, and where they are sympatric there is little evidence of intergradation. Both C. angustifolia var. dubia and C. chromosa are accepted here. See additional comments under 3b. C. angustifolia var. dubia and 15. C. chromosa.

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.
