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.) |
Castilleja revealii is a narrow endemic of limestone gravel barrens on the Markagunt and Paunsaugunt plateaus in and adjacent to the rim of Bryce Canyon National Park and Cedar Breaks National Monument in south-central Utah. It is also known from a single collection from the southwestern edge of the Aquarius Plateau. These xeric barrens have an extremely high amount of reflective sunlight and support few other plants.
