Discussion | Varieties 3 (1 in the flora). Castilleja tenuiflora is common and widespread across the mountains of Mexico, especially in pine-oak-madrone communities at middle elevations, as far south as Oaxaca, where it is found west and north of the Tehuantepec lowlands. There are two varieties of C. tenuiflora endemic to Mexico, while the typical variety crosses into the mountains of southeast Arizona and southwest New Mexico. Considerable local and regional variation exists in C. tenuiflora, but most of this appears to be racial in nature, and additional named varieties are likely not justified. While also commonly herbaceous, C. tenuiflora often forms large, multi-stemmed, subshrub plants with a woody base and ascending to strongly erect and often branched stems. It is valued in Mexican traditional medicine and is under study for potentially useful compounds (M. Jiménez et al. 1995; P. M. Sanchez et al. 2013).

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.) |
