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.

Castilleja lindheimeri is endemic to the Edwards Plateau region. Unlike its close relatives, C. citrina and C. purpurea, most plants of C. lindheimeri have orange to reddish orange inflorescences, with smaller numbers varying to red. The leaves are also often less divided than in either C. citrina or C. purpurea. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
