Discussion | Varieties 3 (3 in the flora). Much confusion exists concerning Castilleja angustifolia and the closely related C. chromosa. Sometimes C. chromosa is treated as a variety of C. angustifolia, using the name C. angustifolia var. dubia. The latter name is used here to represent a different assemblage of plants, not including C. chromosa. At other times, C. chromosa is synonymized completely under C. angustifolia. However, the two species are in most cases easily separable, and where they are sympatric there is little evidence of intergradation. Both C. angustifolia var. dubia and C. chromosa are accepted here. See additional comments under 3b. C. angustifolia var. dubia and 15. C. chromosa.

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.) |
