Castilleja disticha
Castilleja haydenii
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.

Castilleja haydenii is endemic to high-elevation slopes in the Rocky Mountains of southern Colorado and northern New Mexico. It is known in Utah from a single collection from high elevations in the La Sal Mountains. Reports of this species elsewhere are usually attributable to C. rhexiifolia. Its affinities are uncertain. Some features are shared with C. rhexiifolia, but in other ways it resembles species such as C. lemmonii of the Sierra Nevada. Plants in the northwestern portions of its range tend to have less divided leaves. Castilleja haydenii occasionally hybridizes with C. occidentalis where the two commingle in the lower alpine zone.
