▪ plant genus
      the genus and common name for a poisonous annual weed, belonging to the amaranth family (Amaranthaceae), native to southwestern Siberia and northwestern China. There are nine species in the genus. H. sativus yields an ash rich in bases. H. glomeratus, introduced into Nevada about 1930, has since spread widely in the northwestern United States. It is confined to semidesert, salty lands, primarily in disturbed areas such as abandoned fields, abused ranges, and roadsides.

      Halogeton, with reddish stems, varies from a few inches to 2 feet (about 60 cm) tall. The bluish-green leaves, sausage-shaped and bearing a hairlike spine at the tip, are very high in water content. The true flowers are inconspicuous, but the very abundant seeds bear five winglike, whitish bracts; after midsummer the plant is a mass of these showy, flowerlike seeds.

      The high content of oxalates (the dried plants have 5–25 percent of these) makes halogeton poisonous to sheep and cattle. Fortunately, animals do not eat the plant in quantity when other forage is available. Ranges with large amounts of halogeton ordinarily can be safely grazed if livestock are prevented from concentrating on pure stands of the plant. Elimination of the weed by spraying is feasible only in small areas.
