Castilleja brevilobata
Castilleja tomentosa
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.

In the United States, Castilleja tomentosa is known from a number of recently discovered populations in and near the southern Animas Valley, Hidalgo County, where it is found in Bouteloua gracilis and Sporobolus airoides grasslands. All known populations are small, and this species should be considered globally endangered. The only recorded Mexican station was the type locality from 1851 near Mabibi in adjacent northern Sonora. A. Eastwood (1909) believed C. tomentosa was a synonym of C. integra, but that species has mostly entire bracts, while the bracts of C. tomentosa are deeply lobed; the two also have different patterns of coloration and pubescence. T. I. Chuang annotated the holotype sheet of C. tomentosa as C. lanata, but C. tomentosa calyces have fairly deep lateral lobes, unlike the emarginate to very shallowly notched lobes of C. lanata.
