Calyces colored as bracts, (20–) 25–34 mm; abaxial and adaxial clefts (10–) 13–22 mm, 50–60% of calyx length, deeper than laterals, lateral 7–16 mm, 35–45% of calyx length; lobes broadly linear to long-triangular or oblong, apex acute to obtuse.

Discussion

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.
