Discussion | 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 purpurea is a common species of eastern Oklahoma and central Texas, with a few records from adjacent southeastern Kansas and southwestern Missouri. It often provides beautiful, multicolored displays in the meadows within its range. Castilleja citrina and C. lindheimeri are closely related species sometimes regarded as varieties of C. purpurea. Hybrids and hybrid swarms between C. indivisa and C. purpurea have been observed at some localities where they are sympatric.
