--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>annual or perennial; cespitose. <b>Culms</b> 10-150 cm, herbaceous, glabrous, branching both at and above the base. <b>Sheaths</b> open; ligules membranous, ciliate. <b>Inflorescences</b> terminal, panicles of (1)2-20 non-disarticulating, spikelike branches, exceeding the upper leaves; branches 1-17 cm, all or most in a digitate cluster, sometimes 1(2) branch(es) attached immediately below the terminal whorl, axes flattened, terminating in a functional spikelet. <b>Spikelets</b> 3.5-11 mm, laterally compressed, with 2-15 bisexual florets; disarticulation above the glumes and between the florets (<i>E. coracana</i> not disarticulating). <b>Glumes</b> unequal, shorter than the lower lemmas; lower glumes 1-3-veined; upper glumes 3-5(7)-veined; lemmas 3-veined, glabrous, keeled, apices entire, neither mucronate nor awned; paleas sometimes with winged keels; anthers 3, 0.5-1 mm; ovaries glabrous. <b>Fruits</b> modified caryopses, pericarp thin, separating from the seed at an early stage in its development; seeds usually obtusely trigonous, the surfaces ornamented, x = 8, 9, 10.</span><!--

|discussion=<p>Eight of the nine species of <i>Eleusine</i> ate native to Africa, where they grow in mesic to xeric habitats; the exception, <i>E. tristachya</i>, is native to South America. Three species have become established in the Flora region. When moistened, the seeds of all species are easily freed from the thin pericarp.</p><!--
--><p><i>Eleusine coracana </i>subsp.<i> africana</i>, <i>E. indica</i>, and <i>E. tristachya</i> are widely distributed weeds. <i>Eleusine coracana </i>subsp.<i> coracana</i> was domesticated in East Africa and subsequently introduced to India and China. It is frequently grown for grain in India and Africa.</p>
