Discussion
Variety rustica is almost always closely associated with Artemisia tridentata, which is very likely its primary host species. It is found in central Idaho, Montana, and northeastern Oregon. Reports of var. rustica from British Columbia are referred to Castilleja cervina. Apparent hybrids between this variety and C. chromosa are known from Custer County, Idaho.
