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 cryptantha is endemic to the vicinity of Mt. Rainier in the Cascade Range, with most populations found within Mt. Rainier National Park. Unlike most species of Castilleja, it is apparently self-pollinating (W. J. Duffield 1972); the small flowers are entirely enclosed within the yellowish calyces, which tend to grow deep reddish as they age. The purplish brown bracts are also unusual in the genus.
