Discussion | Castilleja disticha is limited to the central and southern Sierra Nevada. Although similar to C. applegatei and C. martini, C. disticha is distinctive and unique in its long, colorful, and highly exserted corollas with the beak exceeding the tube in length, calyces more brightly colored than the often unlobed bracts, and tall, strongly distichous growth form.

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.
