Discussion | Castilleja xanthotricha is endemic to moderate elevations in the sagebrush hills of the John Day River drainage in north-central Oregon. N. H. Holmgren (1971) hypothesized that this tetraploid species is of allopolyploid hybrid origin between C. glandulifera and C. oresbia.

Castilleja wootonii is endemic to the White Mountains (Sierra Blanca) in south-central New Mexico and to the Mt. Livermore massif of western Texas. It should be sought in the intervening Guadalupe Mountains. Based on morphology, C. wootonii appears to be a southern derivative of C. linariifolia.
