Stem erect, short. Leaves 2, flat-winged, flat sickle-shaped, twice as long as flowering stem, curving to one side. Flowers deep pink, 30–90, opening widely, with lance-shaped petals ending in pointed lighter-colored tips that flare or curl back. Stamens extend beyond petals. In seed a narrow constriction is just above ovary. Grows in rocky soils at mid to high elevations. Very similar are the coast flatstem onion, A. falcifolium, and Siskiyou onion, A. siskiyouense.
