Discussion

Variety pinetorum is the most widespread and common representative of the Castilleja applegatei complex. It replaces var. breweri in the Sierra Nevada at low to moderate elevations. On the western flank of Steens Mountain, Harney County, Oregon, var. pinetorum occurs almost exclusively in a yellow-bracted form and has been confused with C. glandulifera. Variety pinetorum hybridizes with C. peckiana in Harney County, Oregon.
