Discussion | Varieties 3 (3 in the flora). 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.

Varieties 2 (2 in the flora). Castilleja scabrida consists of two varieties distinguished by range and habitat differences, as well as by the morphological characters of the key. Both varieties are often confused with the similar and broadly sympatric C. chromosa but can be differentiated from the latter most easily by the presence of scalelike vestigial leaves on the proximal stems of C. scabrida.
