Discussion | Varieties 4 (4 in the flora). Castilleja parviflora is a complex, geographically widespread, and often misunderstood species ranging from southeastern Alaska through much of British Columbia, southwestern Yukon, and the Rocky Mountains of extreme western Alberta and southward in the Cascade Range to central Oregon.

Castilleja nervata is a common and widespread Mexican species, from northern Chihuahua and Sonora south to central Oaxaca. It has medicinal value to indigenous peoples of the Sierra Madre. In the flora area, C. nervata is known from a single, presumably extant population in the Chiricahua Mountains in Cochise County, though there are historical records from the Rincon and Santa Rita mountains. The sole recently verified population is on private property and is endangered. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
