Discussion | 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.) |
Castilleja parvula is limited to the upper elevations of the Tushar Mountains. Morphologically, it appears to be a species derived from the widespread Rocky Mountains species C. rhexiifolia. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
