Castilleja lineata
Castilleja pruinosa
Castilleja lineata is restricted to the mountains of northeastern Arizona, southern Colorado, and northwestern New Mexico. It is uncommon throughout its range and is without apparent close relatives. The Navajo used C. lineata as a medicinal plant and for its sweet nectar (D. E. Moerman 1998).

Castilleja pruinosa is a common and variable paintbrush at moderate elevations in the southern half of the Cascade Range, occurring westward in Oregon and in adjacent northwestern California. It is also found in the northern Sierra Nevada. The often dense pubescence of branched hairs distinguishes it from other similar species within its range. Castilleja gleasoni was sometimes included within C. pruinosa, but C. gleasoni is likely of hybrid origin and occurs only in the San Gabriel Mountains of southern California. There are significant morphological differences between C. gleasoni and C. pruinosa. Castilleja pruinosa forms occasional hybrids with C. applegatei var. pinetorum and with C. brevilobata. In some populations in Douglas and eastern Lane counties, Oregon, C. pruinosa forms introgressive swarms with C. hispida var. hispida.
