--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial; sometimes stoloniferous, sometimes also rhizomatous, often forming dense turf. <b>Culms</b> 4-100 cm. <b>Sheaths</b> open; auricles absent; ligules of hairs or membranous; blades flat, conduplicate, convolute, or involute, sometimes disarticulating. <b>Inflorescences</b> terminal, digitate or subdigitate panicles of spikelike branches; branches (1)2-20, 1-sided, with 2 rows of solitary, subsessile, appressed, imbricate spikelets. <b>Spikelets</b> laterally compressed, with 1(-3) florets, only the lowest floret functional; rachilla extension usually present, sometimes terminating in a reduced floret; disarticulation above the glumes. <b>Glumes</b> usually shorter than the lemmas, membranous, keeled, usually muticous; lower glumes 1-veined; upper glumes 1-3-veined, occasionally shortly awned; lemmas membranous to cartilaginous, 3-veined, keeled, keels with hairs, occasionally winged, apices mucronate or muticous; paleas about as long as the lemmas, 2-keeled; anthers 3; style branches 2, plumose; lodicules 2. <b>x</b> = 9.</span><!--

|discussion=<p><i>Cynodon</i> is a genus of nine species, all of which are native to tropical regions of the Eastern Hemisphere. Several species are used as lawn and forage grasses in tropical and warm-temperate regions. The most widespread species, <i>Cynodon dactylon</i>, is also the most frequently encountered species in the Flora region. It is used for lawns, putting greens, and pastures in southern portions of the region, but is generally considered a weed in other parts.</p><!--
--><p>The status of several species in the Flora region is unclear. Species other than <i>C. dactylon</i> usually grow only under cultivation, but there are scattered records of populations of other species from the southern United States that appear to have become established. Cultivars of <i>C. aethiopicus</i> and C. nlemfuënsis are used for pasture primarily in tropical Florida. <i>Cynodon transvaalensis</i> has had limited commercial distribution as a turf grass.</p><!--
--><p>Many cultivars of <i>Cynodon</i> have been developed, some from hybrids between it and other species such as <i>C. transvaalensis</i>, <i>C. aethiopicus</i>, and C. nlemfuënsis. The cultivars may exhibit combinations of features that are not found in the wild species, making it difficult to accommodate them in a key.</p>
