Castilleja lineata
Castilleja citrina
Castilleja lineata is restricted to the mountains of northeastern Arizona, southern Colorado, and northwestern New Mexico. It is uncommon throughout its range and is without apparent close relatives. The Navajo used C. lineata as a medicinal plant and for its sweet nectar (D. E. Moerman 1998).

Although the range of Castilleja citrina overlaps the range of its close relatives, C. lindheimeri and C. purpurea, in central Texas, C. citrina extends considerably farther to the west and northwest of the others (G. L. Nesom and J. M. Egger 2014). The inflorescences of C. citrina are mostly pale to bright lemon yellow or occasionally brassy yellow. The color and usually more elongate abaxial corolla lip separate it from C. lindheimeri and C. purpurea. Castilleja citrina is similar to some color forms of C. sessiliflora, but the more conspicuously curved corolla of C. sessiliflora is usually exserted far above the calyx and is often white to pale pink, rather than yellow.
