Castilleja chlorotica
Castilleja mexicana
Castilleja chlorotica is an uncommon to rare endemic on dry slopes in Deschutes, Klamath, Lake, and possibly Crook counties in central Oregon. The hooked corolla beak and greenish bracts, often aging purplish distally, help distinguish it from similar species such as C. glandulifera and yellow forms of C. applegatei var. pinetorum.

Castilleja mexicana occurs in the northern third of Mexico and reaches the flora area only in southwestern Texas. Its conspicuous corollas can be either yellow or, less commonly, white. In both cases, the flowers turn soft pink-purple with age. Texas populations of this species are yellow flowered, and the white-flowered morph appears to occur only in northeastern Mexico. There is some indication of additional morphological differences between these color morphs that may justify varietal segregation. Castilleja mexicana is sometimes confused with the closely related C. sessiliflora, due to their conspicuous, distally curved, usually strongly exserted corollas, but the two species remain distinct.
