--><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>Coelorachis 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 Coelorachis and Hackelochloa 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>
