Discussion | Varieties 3 (3 in the flora). Castilleja affinis is highly variable and one of the more common paintbrushes at lower elevations in California, west of the Sierra Nevada, from the northern coast south to northern Baja California. Some recent authors (for example, M. Wetherwax et al. 2012) include C. litoralis of the Pacific Northwest coast as a subspecies of C. affinis, but due to the high polyploid nature of C. litoralis and its significantly closer morphological resemblance to C. miniata var. dixonii, that treatment is not followed here. Also see the comments under 62. C. litoralis. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Variety neglecta is endemic to Marin, Napa, and Santa Clara counties. Its habitat is threatened by urbanization and recreational uses. Within its limited range, it is the only representative of Castilleja affinis on serpentine substrates and is recognized by its relatively narrow, yellow inflorescences.
