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 attenuata is a common and widespread species, ranging from southwestern Canada to northern Baja California, with several disjunct populations in central Chile. It is sensitive to competition from weeds. Disjunct populations in the Rincon Mountains in Pima County, Arizona, often have pink bracts but are otherwise typical.
