Discussion | Castilleja christii is endemic to subalpine meadows near the summit of Mt. Harrison in the Albion Mountains, Cassia County. Morphologically, it most closely resembles the widespread C. hispida var. acuta, but a recent molecular study (D. L. Clay et al. 2012) presents clear evidence for a homoploid hybrid origin for the species, incorporating portions of the genomes of C. linariifolia and C. miniata. This is the first documented case of homoploid origin in Castilleja. Castilleja christii is in the Center for Plant Conservation’s National Collection of Endangered Plants.

Most populations of Castilleja lasiorhyncha are in the San Bernardino Mountains, with a few records in the adjacent Peninsular Ranges immediately to the south. The distal tufts of soft, pale hairs on the immature bracts are apparently unique in the genus. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
