Allium nevii
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.[3][4] DescriptionAllium 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.[3][5] 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.[6] 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.[7] TaxonomyHistorically, Allium nevii was treated as part of the Allium douglasii alliance.[8] Both A. douglasii and A. nevii were placed in the Ownbey Allium falcifolium alliance[9] and subsequently by Traub in subsection Falcifolia, section Lophioprason, subgenus Amerallium (see Taxonomy of Allium).[10] It was formerly considered a variety of Allium douglasii.[7] References
