Flowers 6–9 per involucre; perianth usually magenta, occasionally creamy white, bell-shaped, 1.5–1.8 cm. Fruits mottled olive green, with 10 slender, tan ribs, ellipsoid, 5.5–7 mm, rugulose, glabrous, secreting thick, heavy mucilage when wetted.

Calif., Colo., Nev., Utah.

Discussion

Hermidium was once maintained as a genus based on discrete involucral bracts. As discussed by G. E. Pilz (1978), distinct bracts are typical, but involucres with the five outermost bracts united to one-half their length are common.
