Discussion | Varieties 2 (2 in the flora). Castilleja hispida is likely related to C. chromosa, which replaces it geographically to the southeast. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Castilleja lassenensis is restricted to the Mt. Lassen area in Shasta and Tehama counties. See the discussion of 55. C. lemmonii for information on the relationship between these two species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
