Habit | Herbs, perennial, 0.9–3.8(–4) dm; from a woody caudex; with a taproot. | Subshrubs or herbs, perennial, 1.8–9(–10) dm; from a woody caudex; with a thick, woody taproot or system to thick, branched roots. | ||||||||

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.

Most records of Castilleja lanata are from the southern third of Arizona, New Mexico, and southwestern Texas. Plants sometimes referred to C. lanata from the Channel Islands of California are assigned here to C. hololeuca, an insular endemic. In northern Mexico, C. lanata extends from San Luis Potosí and Nuevo León westward to Sonora, with a disjunct distribution in central Baja California, where it overlaps the southern limits of a related species, C. foliolosa. Castilleja lanata inhabits a wide spectrum of soils and elevations and does not co-occur with the closely related C. galehintoniae in Nuevo León, where the latter is limited to limestone and gypsum substrates in a narrow elevational range. Hybrids of C. lanata with C. sessiliflora are known from Pecos County, Texas. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
