Discussion | Castilleja lineariloba is endemic to the western slope of the Sierra Nevada. Its chromosome number is 2n = 20, an apparent aneuploid reduction and documented by numerous counts. This diploid number is shared only with two very distantly related annual species endemic to central Mexico, C. gracilis Bentham and C. tenuifolia M. Martens & Galeotti.

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.) |
