Discussion | Castilleja attenuata is a common and widespread species, ranging from southwestern Canada to northern Baja California, with several disjunct populations in central Chile. It is sensitive to competition from weeds. Disjunct populations in the Rincon Mountains in Pima County, Arizona, often have pink bracts but are otherwise typical.

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.
