Castilleja puberula
Castilleja haydenii
Castilleja puberula is a near-endemic of alpine communities in the Rocky Mountains of Colorado in Boulder, Clear Creek, Gilpin, Grand, Larimer, and Park counties. A highly disjunct population occurs near the summit of Mt. Jefferson on the Continental Divide in Beaverhead County, Montana. Castilleja puberula appears to be a high-elevation isolate from the widespread C. flava, which is common at lower elevations in the Intermountain Region. A single case of hybridization with C. septentrionalis is known from Clear Creek County.

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.
