Castilleja lineata
Castilleja unalaschcensis
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 unalaschcensis is a characteristic meadow species across much of the southern Alaskan coast, including the Aleutian Islands, as well as on the Queen Charlotte Islands (Haida Gwaii) and the mainland of western British Columbia and southern Yukon. It is common in the coastal littoral zone and ascends to lower alpine meadow communities. Morphologically, it appears to be a sister species to C. septentrionalis of the Rocky Mountains and boreal sites in eastern North America. A weakly differentiated interior form was described as subsp. transnivalis Pennell.
