Discussion | 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.) |
Castilleja genevieveana is known from eight counties in southwestern Texas and from a small area of adjacent Coahuila, Mexico. The species is likely related to the widespread C. integra and geographically replaces it. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
