Castilleja thompsonii
Castilleja patriotica
Castilleja thompsonii is a characteristic species of the sagebrush communities on the eastern slope of the Cascade Range in Washington, and in the high deserts of the Columbia Basin. Historically, its range approached but apparently never entered Idaho in the Spokane River valley, but much of its habitat in that area is now converted to agriculture or suburban development or overwhelmed by non-native, invasive plants. Castilleja thompsonii occurs in a few sites in the Okanogan Valley region of southern British Columbia and at one site on the eastern slopes of the Cascade Range in Wasco County, Oregon. A distinctive form from the subalpine and alpine zones of Mt. Adams, in the southern Cascade Range of Washington, was named C. villicaulis. This form may merit varietal status under C. thompsonii. While both names were described in the same paper, C. thompsonii is the name used in all regional floras since their publication, after C. villicaulis was reduced to synonymy by M. Ownbey (1959).

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.
