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.

Varieties 4 (4 in the flora).

Castilleja applegatei is a widespread and often common species, with complex patterns of variation and several common but inconstant color forms, especially in var. pinetorum. Castilleja disticha and C. martini, although sometimes included as subspecies within C. applegatei, are treated as species here. Both are more morphologically divergent and more easily distinguished from typical C. applegatei than are the four varieties accepted here. Variety pinetorum is the most widespread form and also occurs over a wider range of elevations than the other three varieties, which are primarily montane to subalpine and occasionally alpine.
