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).

Castilleja pulchella is a mostly alpine species of the mountains of western Montana and adjacent Idaho and northwestern Wyoming, as well as in the Uinta Mountains of northeastern Utah. It is similar to and likely shares ancestry with C. chrysantha of the mountains of northeastern Oregon. Castilleja pulchella is variable in color, with inflorescences ranging from pale yellow to purplish, often within the same population. Some lower elevation populations are known. These plants are considerably taller, and they tend to have only yellowish inflorescences. Where the two occur together, C. pulchella occasionally forms hybrids with C. nivea.
