Discussion | Varieties 3 (3 in the flora). Castilleja subinclusa is divided into three varieties with somewhat discontinuous ranges. Identification of the varieties is often difficult when comparing only a single trait but is more easily accomplished when the characters are considered in a suite. The three varieties are also separable by range and habitat. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Castilleja gleasoni is an uncommon plant endemic to the upper elevations of the San Gabriel Mountains of Los Angeles County. It was treated as a polyploid derivative of C. affinis var. affinis (as subsp. affinis) × C. foliolosa (T. I. Chuang and L. R. Heckard 1993b), a hypothetical ancestry supported by a chromosome number of 2n = 72. Others have placed it as a subspecies of C. pruinosa, a similar species. However, the morphology of C. gleasoni also suggests it could have originated as a cross between the diploid C. foliolosa and a tetraploid form of C. martini; careful morphological and molecular analyses are needed to determine its true ancestry. Castilleja gleasoni is in the Center for Plant Conservation’s National Collection of Endangered Plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
