Discussion | Castilleja brevilobata is endemic to dry serpentine openings in the Siskiyou Mountains of southwestern Oregon and adjacent California. Although sometimes treated as part of C. applegatei or C. hispida, its morphology does not suggest a close connection with either. This species occasionally hybridizes with C. pruinosa in Del Norte County, California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Varieties 2 (2 in the flora). Castilleja pallescens occurs from valleys to alpine ridges and summits throughout its range, usually in sagebrush communities, but at higher elevations it is also found on dry sites associated with other plant species. The alpine plants are greatly reduced in stature. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
