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 praeterita is endemic to subalpine, sagebrush-dominated meadows in the southeastern Sierra Nevada of Inyo and Tulare counties. It is closely associated with and likely parasitic on Artemisia rothrockii. Inflorescence coloration varies by population, with some having only yellow-bracted plants, while others are pale orange to pale red with occasional pale yellow variants. Yet other populations have only pale salmon-colored bracts. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
