Discussion | Castilleja lineata is restricted to the mountains of northeastern Arizona, southern Colorado, and northwestern New Mexico. It is uncommon throughout its range and is without apparent close relatives. The Navajo used C. lineata as a medicinal plant and for its sweet nectar (D. E. Moerman 1998).

Castilleja oresbia is endemic to eastern Oregon and adjacent Idaho. It is easily confused with both varieties of C. pallescens, which also occur in sagebrush habitats. Castilleja oresbia has longer calyx lobes and softer pubescence than C. pallescens var. pallescens, although some transitional specimens are found. Castilleja oresbia has a combination of longer calyx lobes, longer pubescence, and obscurely nerved bracts, which usually serve to separate it from C. pallescens var. inverta. All three have different, though somewhat overlapping, ranges. Castilleja oresbia occasionally hybridizes with C. peckiana in Grant County, Oregon.
