Corollas 27–32 mm.


Phenology: Flowering (Mar–)Apr–Jul.
Habitat: Dry sagebrush slopes and flats, often rocky.
Elevation: 2100–3100 m.

Discussion

Most plants of var. flavescens have yellow to pale orange inflorescences, but in some populations, such as near Wells, Nevada, the inflorescence can vary to pink, reddish pink, white, or magenta. Variety flavescens is associated with Artemisia arbuscula, its likely host plant, and is often found at higher elevations than Castilleja chromosa (N. H. Holmgren 1984). The variety is found in southeastern Idaho, eastern Nevada, and western Utah. Recent collections from extreme eastern Mono and Modoc counties suggest that var. flavescens may also occur in California, but the identity of these populations has yet to be fully verified.
