Calyces colored as bracts, 16.5–22 (–27) mm; abaxial and adaxial clefts (8–) 10–15 (–18) mm, 33–40% of calyx length, deeper than laterals, lateral (1.5–) 3–6 (–8) mm, 20–30% of calyx length; lobes narrowly lanceolate to elliptic, apex acute, sometimes obtuse.

Discussion

Castilleja revealii is a narrow endemic of limestone gravel barrens on the Markagunt and Paunsaugunt plateaus in and adjacent to the rim of Bryce Canyon National Park and Cedar Breaks National Monument in south-central Utah. It is also known from a single collection from the southwestern edge of the Aquarius Plateau. These xeric barrens have an extremely high amount of reflective sunlight and support few other plants.
