--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>annual or perennial; aquatic, usually rooted in the substrate; sometimes rhizomatous or stoloniferous; monoecious. <b>Culms</b> to 5 m, erect and emergent or floating. <b>Leaves</b> concentrated on the lower portion of the stem or evenly distributed; sheaths open, not inflated; ligules membranous or scarious, glabrous; pseudopetioles absent; blades flat, aerial or floating, scabrous or smooth. <b>Inflorescences</b> terminal panicles; branches usually unisexual, lower branches staminate, upper branches pistillate, middle branches sometimes with staminate and pistillate spikelets intermixed; pedicel apices cupulate; disarticulation beneath the spikelets, in cultivated strains disarticulation delayed, the spikelets tending not to shatter until harvested. <b>Spikelets</b> unisexual, with 1 floret. <b>Glumes</b> absent; calluses inconspicuous; lemmas 5-veined; paleas 3-veined; lodicules 2, membranous. <b>Staminate</b> spikelets pendant, terete or appearing so; lemmas membranous; paleas membranous, loosely enclosing the stamens; anthers 6. <b>Pistillate</b> spikelets terete; lemmas chartaceous or coriaceous, margins involute and clasping the margins of the paleas, apices acute to acuminate, sometimes awned, awns terminal, slender, scabridulous; styles 2, bases not fused, stigmas laterally exserted, plumose. <b>Caryopses</b> cylindrical; embryos linear, often as long as the caryopses; hila linear, x = 15.</span><!--

|discussion=<p><i>Zizania</i> includes three North American and one eastern Asian species. <i>Zizania aquatica</i> and <i>Z. palustris</i> are important constituents of aquatic plant communities in North America, providing food and shelter for numerous animal species. <i>Zizania palustris</i> is also an important food source for humans. <i>Zizania texana</i> is federally listed as an endangered species in the United States. <i>Zizania latifolia</i>, an Asian species, is available through horticultural outlets despite its potential for harboring a fungus that would devastate the native species (for additional information, see the comment following the species description).</p>
