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.) |
Variety acuta sporadically replaces var. hispida on the eastern slope of the Cascade Range and extends eastward from there to southwestern Montana and northeastern Oregon. Variety acuta hybridizes with Castilleja lutescens in Garfield County, Washington. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
