Allium nevii, known by the common name Nevius' onion or Nevius' garlic, is a plant species native to central Washington (Klickitat, Yakima, Kittitas and Chelan Counties) and north-central Oregon (Wasco and Hood River Counties) in the United States. It grows in wet meadows and along stream banks at elevations up to 2000 m.[http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=242101379 Flora of North America v 26 p 267, Allium nevii][http://bonap.net/MapGallery/County/Allium%20nevii.png BONAP (Biota of North America Program) floristic synthesis, Allium nevii]
Description
Allium nevii produces egg-shaped bulbs up to 2 cm across. One plant will generally have 1-3 scapes, each round or slightly flattened and up to 25 cm tall. Flowers are in umbels of as many as 30 flowers, each bell-shaped and about 7 mm across. Tepals are rose-colored; anthers and pollen blue.[https://www.biodiversitylibrary.org/page/8714524#page/241/mode/1up Watson, Sereno. 1879. Proceedings of the American Academy of Arts and Sciences 14: 231.] The inner coats range from reddish to white. The outer coats range from gray and brown. The thin membrane has a unique network pattern. The flowers bloom period is between May and June.{{Cite web |title=Allium nevii - Burke Herbarium Image Collection |url=https://burkeherbarium.org/imagecollection/taxon.php?Taxon=Allium%20nevii |access-date=2023-08-19 |website=burkeherbarium.org}} It has two basal leaves, one leaf-less scape, and a cluster of flowers at its tip. The six tepals are narrowly lanceolate with pointed tips. The tepals are usually pink, and rarely white.{{Cite web |title=Nevius' Garlic, Nevius' Onion: Allium nevii (Synonym: Allium douglasii var. nevii) |url=http://science.halleyhosting.com/nature/basin/3petal/lily/allium/nevii.htm |access-date=2023-08-19 |website=science.halleyhosting.com}}
Taxonomy
Historically, Allium nevii was treated as part of the Allium douglasii alliance.{{sfn|Rieseberg et al|1987}} Both A. douglasii and A. nevii were placed in the Ownbey Allium falcifolium alliance{{sfn|Saghir et al|1966}} and subsequently by Traub in subsection Falcifolia, section Lophioprason, subgenus Amerallium (see Taxonomy of Allium).{{sfn|Traub|1968}} It was formerly considered a variety of Allium douglasii.
