Castilleja pruinosa
Castilleja patriotica
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.

Castilleja patriotica is broadly distributed in the northern Sierra Madre Occidental in Mexico, south to northern Durango and Sinaloa. It is replaced in central and southern Mexico by a related species, C. pectinata M. Martens & Galeotti. Castilleja patriotica reaches the Chiricahua and Huachuca mountains of southeastern Arizona and the adjacent Animas Mountains of southwestern New Mexico. A report from the Atascosa Mountains of southern Arizona needs verification. The numerous, narrow axillary leaves and the narrow leaf lobes combine to give this plant a curious frilly appearance. The narrow, widely divaricate lateral leaf lobes are unique in the flora area. Short, compact plants with smaller flowers were named C. blumeri. Castilleja patriotica has medicinal value to native peoples of the northern Sierra Madre.
