Genus Hordeum

Plants annual or perennial . Culms usually erect . Leaf sheath of cauline leaves split almost to base ; ligule membranous or leathery-membranous; auricles present or absent; leaf blade usually flat. Spike dense, usually without a terminal spikelet ; rachis short, brittle, rarely flexible . Spikelets usually 3 per node, in regular rows , with 1(or 2) florets ; lateral spikelets usually pedicellate , rarely sessile, often reduced and much smaller than central spikelet; central spikelet usually sessile, rarely pedicellate, perfect . Glumes narrow, subulate-setaceous, sometimes lanceolate dilated at base, inconspicuously 1-3-veined, not keeled . Lemma subrounded abaxially, leathery, rarely leathery-membranous, 5-veined, not keeled, awned or awnless. Palea almost equaling lemma, glabrous , scabrous , or ciliate along keels. Lodicules broadly lanceolate or lanceolate-ovate. Caryopsis usually adnate to lemma and palea, rarely free , oblong , concave furrowed on inner side, apex hairy . x = 7.

Between 30 and 40 species: temperate regions , also on subtropical mountains; ten species (one endemic, two introduced ) in China.

All species when young are used for forage .[1]
