Discussion | Castilleja lineata is restricted to the mountains of northeastern Arizona, southern Colorado, and northwestern New Mexico. It is uncommon throughout its range and is without apparent close relatives. The Navajo used C. lineata as a medicinal plant and for its sweet nectar (D. E. Moerman 1998).

Castilleja chambersii is limited to the summits of three volcanic peaks in the northern Coast Range of Clatsop County, Oregon, and at one similar area in nearby Pacific County, Washington. It is similar to C. rupicola, and the two likely share a common ancestor. Disturbance and erosion from logging and road construction represent significant threats to C. chambersii. Populations of C. chambersii often grow near and even alongside C. hispida, but hybrids are rare. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
