Discussion | Castilleja lutescens is found east of the Cascade Range in Oregon and Washington and ranges east to western Montana and the adjacent interior of western Canada. Its inflorescences vary in color from entirely greenish to white or yellowish, and the stature of the plants is also variable, trending from moderate and compact in grasslands to taller in more forested situations. In the Blue Mountains of Garfield County, Washington, occasional hybrids form between C. lutescens and C. hispida var. acuta, which often both occur in the same vicinity. L. R. Heckard (1968) reported a chromosome count of ca. 2n = 120 from a population in Montana. (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.
