Discussion | Castilleja nelsonii is fairly common in the upper elevations of the so-called sky island ranges from central and eastern Arizona to adjacent New Mexico, southward into the Sierra Madre Occidental, at least as far south as southern Chihuahua, where the type collection was obtained on Cerro Mohinora. Although it was long known in the United States as C. austromontana, the name C. nelsonii has priority. Some specimens from southern Coconino County, Arizona, approach C. miniata, but most material is easily separable. Castilleja nelsonii occasionally hybridizes with C. mogollonica in Apache County, Arizona, near the border of the range of the former.

Castilleja chrymactis is restricted to the coast of southeastern Alaska, from Glacier Bay to Yakutat. In some respects, it resembles a hybrid swarm between C. miniata and C. unalaschcensis. If C. chrymactis originated as a hybrid, at present it has formed a number of populations and has a stable morphology that differs from both putative parents, especially in calyx structure. Reports of its introduction to Point Reyes, California (T. I. Chuang and L. R. Heckard 1993b), are based on C. leschkeana, a distinctive species known only from two records near the type locality and presumed to be extinct.
