Allium anceps, known as twinleaf onion[1] and Kellogg's onion,[2] is a species of wild onion native to the western United States. It is widespread in Nevada, extending into adjacent parts of California, Idaho, and Oregon.[2] It grows in barren clay and rocky soils.[2] [3] [4]
This perennial herb produces a flowering scape from a bulb up to 2frac=4NaNfrac=4 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 26cm (10inches) long. The scape is erect, up to 150NaN0 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 1frac=3NaNfrac=3 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]
