Discussion | Castilleja brevilobata is endemic to dry serpentine openings in the Siskiyou Mountains of southwestern Oregon and adjacent California. Although sometimes treated as part of C. applegatei or C. hispida, its morphology does not suggest a close connection with either. This species occasionally hybridizes with C. pruinosa in Del Norte County, California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Castilleja revealii is a narrow endemic of limestone gravel barrens on the Markagunt and Paunsaugunt plateaus in and adjacent to the rim of Bryce Canyon National Park and Cedar Breaks National Monument in south-central Utah. It is also known from a single collection from the southwestern edge of the Aquarius Plateau. These xeric barrens have an extremely high amount of reflective sunlight and support few other plants.
