Discussion | Castilleja salsuginosa is endemic to a single site in White Pine County, where it is limited to the harsh alkaline soils of travertine hot springs. This population is threatened by habitat degradation from livestock, as well as by water developments affecting the hydrology of the hot spring system. Castilleja salsuginosa is closely related to C. nana and C. pilosa, but genetic studies of the trio are inconclusive so far. Two populations of very similar but slightly smaller-flowered plants occur around other hot springs in adjacent Eureka County. While they resemble C. salsuginosa superficially, recent morphometric studies of one of these populations indicate that they may be worthy of nomenclatural recognition, separate from C. salsuginosa. Castilleja salsuginosa is in the Center for Plant Conservation’s National Collection of Endangered Plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Castilleja wootonii is endemic to the White Mountains (Sierra Blanca) in south-central New Mexico and to the Mt. Livermore massif of western Texas. It should be sought in the intervening Guadalupe Mountains. Based on morphology, C. wootonii appears to be a southern derivative of C. linariifolia.
