Discussion | Castilleja chromosa is sometimes confused with 3b. C. angustifolia var. dubia (see discussion there). Castilleja chromosa retains its distinctive morphology across its wide range and is a characteristic species of much of the southwestern United States. Where it overlaps with C. angustifolia, the two are distinguished by inflorescence color and width and by the lengths of the calyx, corolla, and corolla beak. In the broad region of their sympatry, there is little evidence of intergradation, except in a few sites in Elko County, Nevada, and in southern Wyoming. Throughout southern Idaho and northeastern Nevada the range of the two overlap with little or no intergradation. At high elevations in Montrose County, Colorado, C. chromosa has narrower leaves and a longer and silkier pubescence, especially in the inflorescence. Apparent hybrids between C. chromosa and C. flava var. rustica are known from Custer County, Idaho, and hybrids with C. linariifolia are known from Montrose County, Colorado.

Castilleja cervina is found across northern Washington, from the eastern slope of the Cascade Range, east to northern Idaho and north to southern British Columbia. Plants at higher elevations are dwarfed. Reports from Montana need verification. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
