Discussion

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.

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.
