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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Varieties 3 (3 in the flora). In addition to the characters in the key, Castilleja exserta is distinguished from the similar C. densiflora by its conspicuously hairy and apically hooked beak. As a result, the capitate stigma is exserted more or less horizontally from the corolla beak. In contrast, C. densiflora has an unhooked, inconspicuously puberulent beak, from which the stigma emerges more vertically. Castilleja exserta hybridizes with C. attenuata in southern California and with C. lineariloba in central California, and it reportedly crosses occasionally with C. densiflora in southern California.
