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 levisecta is listed as threatened in the United States and endangered in Canada, where it is extremely rare. Most of its grassland habitat has been altered by development in the Puget Trough, and there are historical stations in the metro areas of what are now Victoria, Portland, and Seattle. For several decades, C. levisecta was considered extirpated from Oregon. However, recent reintroduction programs in Oregon and Washington have been very successful at reestablishing this species at several sites in the Willamette Valley. The bright yellow inflorescences often gradually age to a golden yellow color, unique in the genus. Castilleja levisecta is in the Center for Plant Conservation’s National Collection of Endangered Plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
