--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial; strongly rhizomatous. <b>Culms</b> 20-130 cm, erect, glabrous. <b>Leaves</b> mostly basal; sheaths open; auricles absent; ligules membranous, sometimes ciliolate; blades 0.5-8 mm wide, involute or convolute. <b>Inflorescences</b> terminal panicles, dense, cylindrical; branches strongly ascending and overlapping. <b>Spikelets</b> pedicellate, laterally compressed, with 1 floret; rachillas prolonged beyond the florets, glabrous or hairy; disarticulation above the glumes, beneath the florets. <b>Glumes</b> equaling or exceeding the florets, subequal, linear-lanceolate, papery, keeled, acute to acuminate; lower glumes 1-veined; upper glumes 3-veined; calluses short, pilose; lemmas chartaceous, linear-lanceolate, obscurely 3-5-veined, keeled, sometimes slightly rounded at the base, apices entire or minutely bifid, unawned or awned, awns 0.2-0.5 mm, subterminal; paleas equaling the lemmas, often appearing 1-keeled, 2- or 4-veined, central veins close together; lodicules 2, free, membranous, ciliate or glabrous, not toothed; anthers 3, 3-7 mm; ovaries glabrous. <b>Caryopses</b> enclosed by the hardened lemma and palea, ellipsoid, longitudinally grooved; hila about 2/3 as long as the caryopses. <b>x</b> = 7.</span><!--

|discussion=<p><i>Ammophila</i> has two species, one native to the coast of Europe and northern Africa, and one to eastern North America. Both species are effective sand binders and dune stabilizers. They are sometimes mistaken for <i>Leymus arenarius</i> and <i>L. mollis</i>, which grow in the same habitats and have a similar habit, but species of <i>Leymus</i> have more than 1 floret per spikelet.</p>
