Discussion | Castilleja chlorotica is an uncommon to rare endemic on dry slopes in Deschutes, Klamath, Lake, and possibly Crook counties in central Oregon. The hooked corolla beak and greenish bracts, often aging purplish distally, help distinguish it from similar species such as C. glandulifera and yellow forms of C. applegatei var. pinetorum.

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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
