Discussion

Varieties 2 (2 in the flora).

Castilleja pallescens occurs from valleys to alpine ridges and summits throughout its range, usually in sagebrush communities, but at higher elevations it is also found on dry sites associated with other plant species. The alpine plants are greatly reduced in stature.
