--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>annual; synoecious. <b>Culms</b> 1-75 cm, erect to geniculately ascending, sometimes branching above the base; nodes usually exposed. <b>Sheaths</b> open, often becoming inflated, junction with the blades evident; ligules of hairs; auricles absent; blades often disarticulating. <b>Inflorescences</b> terminal or terminal and axillary, spikelike or capitate panicles subtended by, and often partially enclosed in, 1 or more of the uppermost leaf sheaths, additional panicles often present in the axils of the leaves below. <b>Spikelets</b> 2-6 mm, strongly laterally compressed, with 1 floret; florets bisexua; disarticulation above or below the glumes. <b>Glumes</b> 1-veined, strongly keeled; lemmas membranous, glabrous, 1-veined, strongly keeled, not lobed, unawned, sometimes mucronate; paleas hyaline, 1-2-veined; lodicules absent; anthers 2 or 3; ovaries glabrous. <b>Fruits</b> oblong, pericarp loosely enclosing the seed and easily removed when wet; hila punctate, x = 8.</span><!--

|discussion=<p><i>Crypsis</i>, a genus of eight species, is native from the Mediterranean region to northern China. Its species tend to occur in moist soils, often in areas subject to winter flooding. The three species found in the Flora region are very plastic in the lengths of their culms and leaves, e.g., the culms of <i>C. schoenoides</i> vary from 2 cm in dry sites to 75 cm under optimal conditions.</p>
