Castilleja lemmonii
Castilleja rigida
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.

Castilleja rigida is endemic to desert scrub on limestone deposits in the Chihuahuan Desert region and the adjacent western edge of the Edwards Plateau. It is almost always closely associated with, and most likely parasitic on, Agave lechuguilla. The majority of its range is in the Mexican states of Chihuahua, east of the Sierra Madre Occidental, as well as in Coahuila and Nuevo León, where it is a characteristic component of the regional flora, but also extends into a few counties in southwestern Texas. It is sometimes confused with the similar species, C. nervata, which is widespread in the sierras of western Mexico and is known from a single extant population in the western Chiricahua Mountains of southeastern Arizona. Castilleja nervata and C. rigida are largely parapatric in Mexico.
