Discussion | Castilleja suksdorfii is endemic to wet habitats in the Cascade Range from the Goat Rocks Wilderness Area in Yakima County, Washington, south to the vicinity of Crater Lake National Park in Klamath County, Oregon. Reports of this species farther north in Washington and southern British Columbia are referable to C. rupicola. Castilleja suksdorfii is a polyploid species and may be of hybrid origin.

Castilleja aquariensis is endemic to the Aquarius Plateau in the mountains of south-central Utah. Its meadow habitats were severely degraded by livestock grazing, and at one time the species was a candidate for listing under the Endangered Species Act of the United States. It is still a species of management concern. Castilleja aquariensis is in the Center for Plant Conservation’s National Collection of Endangered Plants.
