Discussion | Castilleja peirsonii is endemic to the higher elevations in the Sierra Nevada of California and in Tahoe Meadows in adjacent Washoe County, Nevada. Plants with yellow bracts in the southern portion of the range were named C. carterae. Castilleja peirsonii has shorter, wider corolla beaks than the related C. parviflora. In addition to the corolla shape differences, C. peirsonii also has red to yellow bracts and fairly bright yellow corollas, especially on the beaks, while C. parviflora has purple, pink, or white bracts and greenish corolla tubes and dorsal beak surfaces, with the beak margins pink, purple, or white. Reports from outside the Sierra Nevada in California and immediately adjacent Nevada are misidentifications. Castilleja peirsonii sometimes hybridizes with C. lemmonii in meadows where both species often occur in large numbers. (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.
