This perennial herb produces a flowering scape from a bulb up to 2 cm (3⁄4 in) long and wide. There are up to 5 bulbs, sometimes wrapped together in the brown or yellow-brown outer coat. There are two flat, smooth-edged, sickle-shaped leaves up to 26 cm (10 in) long. The scape is erect, up to 15 cm (6 in) tall, and flattened with winged edges. It bears an umbel of 15 to 35 flowers with two spathes at the base. The star-shaped flower is roughly 1 cm (1⁄3 in) wide with six greenish-veined pink tepals. The six stamens are tipped with yellow anthers bearing yellow pollen. Once the seeds mature the scape dies and breaks off, usually along with the leaves.[4][5]

The bulbs are edible and were a food source for the Northern Paiute, who roasted them and pressed them into cakes.[6]
