Plants perennial or annual; aquatic, rooted and emergent; rhizomatous; monoecious. Culms 1-4 m, erect or decumbent, sometimes rooting at the nodes. Leaves basal and cauline; sheaths open, somewhat laterally compressed; ligules scarious; pseudopetioles absent; blades flat or folded at the base, lanceolate. Inflorescences terminal panicles, staminate and pistillate spikelets on the same branches, staminate spikelets proximal, pistillate spikelets distal; disarticulation beneath the spikelets; pedicel apices cupulate. Spikelets unisexual, laterally compressed to subterete, lemma margins not clasping the paleas, with 1 floret. Glumes absent; calluses glabrous. Staminate lemmas membranous, 5-7-veined, acuminate or terminally awned; paleas similar to the lemmas, 3-veined; lodicules 2; anthers 6. Pistillate lemmas membranous, 7-veined, terminally awned; paleas similar to the lemmas, 3-veined, awned or unawned; styles 2, bases fused, stigmas terminally exserted, plumose. Fruits achenes, ellipsoid or obovoid, beaked by the persistent style base; pericarps shell-like, partially free from the seed, smooth, coriaceous or crustaceous; seeds oblong, subterete, or 2-angled; embryos basal; hila linear, x = 12.
