Much confusion exists concerning Castilleja angustifolia and the closely related C. chromosa. Sometimes C. chromosa is treated as a variety of C. angustifolia, using the name C. angustifolia var. dubia. The latter name is used here to represent a different assemblage of plants, not including C. chromosa. At other times, C. chromosa is synonymized completely under C. angustifolia. However, the two species are in most cases easily separable, and where they are sympatric there is little evidence of intergradation. Both C. angustifolia var. dubia and C. chromosa are accepted here. See additional comments under 3b. C. angustifolia var. dubia and 15. C. chromosa.

Castilleja cusickii includes two morphologically distinct variants. One variant has a wider inflorescence, broader bracts, and wider bract lobes. These bracts often have highly contrasting purple veins, and some populations also have a purplish wash on the bracts. These plants have a range on the western edge of typical C. cusickii, though overlapping with more typical forms in western Idaho and adjacent northeastern Oregon and southeastern Washington. The name C. lutea is available for these variants, and both consistent morphological differences and preliminary results from ongoing genetic research on the plants (D. C. Tank, pers. comm.) indicate its resurrection may be justified. A second variant is distinguished by a pale pink-purple wash on the bracts and a narrow distribution in the meadows of the Bear River Valley, bordering northwestern Utah and adjacent southeastern Idaho. Only bract coloration appears to distinguish this form from typical C. cusickii, and the distinctive bract coloration is only more or less consistent in these populations.

Typical Castilleja cusickii appears to hybridize with C. gracillima in the Logan Valley, Grant County, Oregon. It is also reported by M. Ownbey (1959) to hybridize with C. miniata and C. rhexiifolia.
