--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial; cespitose or rhizomatous. <b>Culms</b> 60-400 cm, erect. <b>Leaves</b> not aromatic; basal and cauline; sheaths open, glabrous, margins scarious; auricles lacking; ligules membranous, ciliate; blades flat to conduplicate, glabrous or sparsely pubescent, margins scarious, sometimes scabrous. <b>Inflorescences</b> terminal and axillary, composed of a solitary, pedunculate rame; rames stout; disarticulation in the rames, below the sessile spikelets. <b>Spikelets</b> dorsally compressed, in heterogamous sessile-pedicellate pairs. <b>Sessile</b> spikelets embedded in the rame axes, ovate, with 2 florets, unawned; lower glumes indurate, smooth, rugose, or pitted, 7-11-veined, not keeled; upper glumes coriaceous, keeled, 1-veined; lower florets sterile; upper florets bisexual, unawned; anthers 3. <b>Pedicels</b> short, thick, appressed or partly fused to the side of the rame axes. <b>Pedicellate</b> spikelets 1-3 mm, usually reduced. <b>Caryopses</b> ellipsoid to broadly ellipsoid, yellow. <b>x</b> = 9.</span><!--

|discussion=<p><i>Coelorachis</i> is a tropical genus of approximately 20 species; four are native to the southeastern United States. Most species tend to favor damp soils. Veldkamp et al. (1986) recommended combining <i>Coelorachis</i> and <i>Hackelochloa</i> with some other small genera in Mnesithea Kunth, but these two seem to be sufficiently distinct to be maintained until more data are available.</p>
