--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial; cespitose, sometimes rhizomatous. <b>Culms</b> 20-203 cm, solitary or clustered, often rooting at the lower nodes, usually glabrous. <b>Sheaths</b> open, glabrous; auricles absent; ligules scarious; blades flat, margins scabrous, surfaces scabrous or smooth. <b>Inflorescences</b> panicles; branches spreading to ascending, some branches longer than 1 cm; pedicels slightly flared, scabrous or smooth; disarticulation below the glumes. <b>Spikelets</b> laterally compressed, with 1 floret, rarely with a second rudimentary or fertile floret; rachillas usually prolonged beyond the base of the floret as a minute stub or bristle, smooth or scabridulous, sometimes not prolonged. <b>Glumes</b> from slightly shorter than to slightly longer than the floret, 1- or 3-veined, margins hyaline, keeled, keels scabrous, apices acute, sometimes minutely awn-tipped; lower glumes from somewhat shorter than to equaling the upper glumes, florets sessile or stipitate; calluses short, glabrous; lemmas 3- or 5-veined, sometimes obscurely so, apices acute, minutely bifid, usually awned, awns subterminal, sometimes unawned; paleas 3/4 to nearly as long as the lemmas, 1-veined or with 2 closely spaced veins; anthers 1 or 2. <b>Caryopses</b> shorter than the lemmas, concealed at maturity, often beaked, x = 7.</span><!--

|discussion=<p><i>Cinna</i> is a genus of four species, all of which generally grow in damp woods, along streams, or in wet meadows. One species, <i>C. latifolia</i>, is northern temperate and circumboreal. The other three species are restricted to the Western Hemisphere. <i>Cinna</i> poaeformis (Kunth) Scribn. & Merr. extends from Mexico to Venezuela and Bolivia.</p><!--
--><p>The reduction of <i>Limnodea</i> to synonymy under <i>Cinna</i> by Tucker (1996) introduced a markedly discordant element into <i>Cinna</i> (Brandenburg and Thieret 2000), and has not been followed here.</p>
