--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial; synoecious; rhizomatous, rhizomes short or elongate. <b>Culms</b> 50-250 cm, solitary or few. <b>Leaves</b> cauline; sheaths open; ligules of hairs, dense, short; blades elongate, long tapering. <b>Inflorescences</b> terminal, simple panicles, usually exserted and exceeding the upper leaves, open to contracted; panicles 8-80 cm long, to 60 cm wide, simple, flexible, branches not spikelike, not disarticulating. <b>Spikelets</b> with 1 floret, laterally compressed, unawned; rachillas not prolonged; disarticulation above the glumes, achenes falling with the lemmas and paleas. <b>Glumes</b> subequal to unequal, 1-veined, acute; calluses evidently hairy, hairs 1/4 - 7/8 as long as the lemmas; lemmas similar to the glumes, from shorter than to longer than the upper glumes, 1-veined, acute, unawned; paleas longitudinally grooved; anthers 3, 2.4-5.5 mm; ovaries glabrous. <b>Fruit</b> an achene, pericarp free from the seed, x = 10.</span><!--
