|discussion=<p><i>Castilleja unalaschcensis</i> 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 <i>C. septentrionalis</i> of the Rocky Mountains and boreal sites in eastern North America. A weakly differentiated interior form was described as subsp. transnivalis Pennell.</p>
