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.) |
Varieties 2 (2 in the flora). Castilleja campestris is sometimes confused with Triphysaria eriantha subsp. eriantha, but C. campestris has two-celled anthers and entire leaves, while T. eriantha has one pollen sac per stamen and strongly divided leaves.
