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.

Castilleja sessiliflora ranges across the Great Plains from southern Canada to northern Mexico, where it is apparently rare. In Texas and northern Mexico, its range overlaps with the similar C. mexicana. Most populations of C. sessiliflora, especially north of Texas, have white to pale yellow inflorescences; in southwestern Texas they are more variable in color, with pink-purple plants often predominating locally. Those plants with pink-purple inflorescences were named forma purpurina by F. W. Pennell. In the limestone deserts of southern New Mexico and southeastern Arizona, the inflorescences are often a pale pink-orange, but these are intermingled with more typical greenish white plants. Occasional hybrids between C. angustifolia var. dubia and C. sessiliflora are known from northeastern Wyoming.
