Inflorescences 1–20(–60)-flowered, 0.5–7 cm diam. Flowers: hypanthium campanulate, ± as deep as wide; petals yellow; anthers 0.6–1 mm.
Phenology: Flowering summer.
Habitat: Dry, rocky outcrops of calcareous or volcanic origin, usually in crevices of more or less vertical protected cliffs or large boulders, in sagebrush communities, conifer woodlands
Elevation: 1200–2400(–3400) m
Distribution
Ariz., Calif., Nev., Utah.
Discussion
Of conservation concern.
Variety arizonica occurs as isolated populations from the Funeral and Grapevine mountains, Inyo County, California, to the Kolob Plateau of Washington County, Utah, and on the walls of the Grand Canyon and in the Oak Creek Canyon area of northern Arizona. Significant variation in vestiture, hypanthium depth, and other features occurs among these widely scattered population clusters. High-elevation plants (3100–3400 m) from the Troy Peak area of the Grant Range in northeastern Nye County, Nevada, are notably depauperate (0.2–0.5 dm) with leaflets 2–5 mm and petals 1.6–2.5 mm. All other populations occur below 2400 m.
