Discussion | 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.

Castilleja martini is sometimes treated as a subspecies of C. applegatei, but there are relatively consistent morphological discontinuities between these two variable complexes. See notes under 4. C. applegatei. Varieties 2 (2 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
