Discussion

Castilleja lineata is restricted to the mountains of northeastern Arizona, southern Colorado, and northwestern New Mexico. It is uncommon throughout its range and is without apparent close relatives. The Navajo used C. lineata as a medicinal plant and for its sweet nectar (D. E. Moerman 1998).

Castilleja tenuis is restricted to the east side of the Cascade Range in British Columbia and Washington and also occurs west of the Cascade-Sierra axis in the more arid terrain of California and Oregon. Plants in the Umpqua and Willamette valleys of western Oregon are often taller, more robust, and with slightly larger flowers than is typical in other regions. There are two color forms, with white or yellow corollas, but most individual populations are consistently unicolored. More investigation is needed to determine if corolla color is influenced by genetic and/or environmental factors. There is some evidence (T. I. Chuang and L. R. Heckard 1982) that the colors are correlated to chromosome number, with the white-flowered plants being diploid, while the yellow-flowered plants are tetraploid; however, there are exceptions. D. D. Keck (1927) cited some evidence for seasonal change, with yellow flowers occurring early, replaced with white flowers later in the season. However, no unequivocal evidence exists to support this hypothesis, and the apparently complete absence of yellow-flowered plants in Oregon makes this an unlikely explanation. Cropping by grazing animals results in occasional plants that branch. Plants with slightly curved corolla beaks were described as Orthocarpus falcatus but have no geographic integrity or taxonomic significance. Castilleja tenuis was collected as a waif in Skagway, Alaska, a century ago.
