Discussion | Castilleja mendocinensis is a coastal plant from Mendocino County, California, northward to Curry County, Oregon. Its close relative, C. latifolia, occurs in similar habitats south of San Francisco Bay. There is one known population in Oregon, and a number of California localities are threatened by coastal development. (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.
