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.

Castilleja nana is limited to high elevations in the Sierra Nevada of California and the Great Basin ranges in central Nevada and western Utah. Plants with pink to purple inflorescences were described as C. lapidicola. Localized hybrid swarms between C. nana and C. viscidula are known from several mountain ranges in central and northern Nevada. Castilleja nana is sometimes confused with higher elevation forms of C. pilosa but can usually be distinguished from that species by the blackish patches on the sides of the corolla tube. Divergent populations in the central Sierra Nevada and adjacent White Mountains deserve further study. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
