Discussion | Castilleja montigena is endemic to the northeastern portion of the San Bernardino Mountains of southern California. In the field, this species is consistently and relatively easily distinguished from nearby populations of C. martini var. martini, which it essentially replaces in the northeastern portion of the San Bernardino Mountains. It is apparently of allopolyploid hybrid origin between C. martini var. martini and C. chromosa, which approaches its range from the adjacent Mojave Desert.

Varieties 2 (2 in the flora). Castilleja scabrida consists of two varieties distinguished by range and habitat differences, as well as by the morphological characters of the key. Both varieties are often confused with the similar and broadly sympatric C. chromosa but can be differentiated from the latter most easily by the presence of scalelike vestigial leaves on the proximal stems of C. scabrida.
