Discussion | Varieties 4 (4 in the flora). Castilleja parviflora is a complex, geographically widespread, and often misunderstood species ranging from southeastern Alaska through much of British Columbia, southwestern Yukon, and the Rocky Mountains of extreme western Alberta and southward in the Cascade Range to central Oregon. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
