Discussion | Varieties 4 (4 in the flora). Castilleja miniata is widely recognized as the common scarlet paintbrush. It is highly variable and has five levels of polyploidy. Nonetheless, it remains fairly well defined morphologically across its wide range. Native Americans use it medicinally. A probable hybrid with C. septentrionalis from southern Nevada was named C. ×porterae Cockerell. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Castilleja kaibabensis is endemic to a few large meadow systems on the Kaibab Plateau, north of the North Rim of the Grand Canyon in Coconino County. Recreational activity, grazing, and road construction remain concerns for the management of this species. Castilleja kaibabensis is in the Center for Plant Conservation’s National Collection of Endangered Plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
