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.) |
Castilleja collegiorum is endemic to a large meadow system in the southern Cascade Range of Klamath County. It is similar to C. cryptantha in Washington and C. lemmonii in California but differs from both in structural details of the inflorescence, calyx, bracts, and leaves.
