Discussion | 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.

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.
