Castilleja lanata
Castilleja hyperborea
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.

Castilleja hyperborea is widespread across boreal, alpine, and arctic habitats in western Canada and Alaska, extending into the Russian Far East. A rare form with light purple bracts was named as C. kuschei. Another form with particularly long hairs found in the Kluane Lake region of the southern Yukon was described as C. villosissima and is usually found on calcareous substrates.
