Discussion

Variety scabrida inhabits sandstone-derived soils in high deserts and the surrounding mountains, in Utah and adjacent western Colorado as well as a handful of records from northeastern Arizona and northwestern New Mexico. Variety scabrida is related to, and often confused with, Castilleja chromosa, but the latter species is usually a sagebrush associate, while C. scabrida shows no special differences for Artemisia. Variety scabrida occasionally hybridizes with C. linariifolia.
