Discussion | Castilleja brevilobata is endemic to dry serpentine openings in the Siskiyou Mountains of southwestern Oregon and adjacent California. Although sometimes treated as part of C. applegatei or C. hispida, its morphology does not suggest a close connection with either. This species occasionally hybridizes with C. pruinosa in Del Norte County, California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Castilleja glandulifera is endemic to the upper elevations of the Blue and Strawberry mountains of northeastern Oregon, as well as a few adjacent minor ranges. It is related to C. applegatei and C. viscidula, which are the source of reports of C. glandulifera in the Wallowa Mountains and on Steens Mountain. Inflorescences of C. glandulifera are usually white to pale yellow, but in the area around Marble Creek Pass in Baker County, they are multicolored, with a variety of reddish shades mixed in among the yellowish plants. Castilleja glandulifera and C. viscidula share a glandular pubescence, divided leaves, and usually yellowish inflorescences. Castilleja glandulifera is distinguished from C. viscidula by its taller stature, longer corolla beak, and more deeply divided leaves and bracts with linear to linear-lanceolate lobes. Castilleja glandulifera differs from C. applegatei by its unusual leaves and bracts as well as by its habitat and narrower and somewhat shorter corolla beak.
