Discussion | 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 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.) |
