Plants perennial; emergent aquatic or terrestrial, rooting at the lower nodes. Culms 100-150 cm, erect, succulent, with short innovations; nodes glabrous; internodes glabrous. Sheaths compressed, not keeled, overlapping but narrow, exposing the nodes, bladeless and glabrous or sparsely pilose below the water; ligules 1-2 mm, membranous, ciliate; blades 1-30 cm long, 2-4 mm wide, narrow, linear, flat or folded, abaxial surfaces sparsely pubescent, adaxial surfaces sparsely pilose. Panicles 10-30 cm, open, with many spikelets; primary branches fascicled at the base of the panicles, solitary and distant distally; pedicels 1-4 mm, sharply 3-angled, appressed. Spikelets 2-2.2 mm, glabrous. Lower glumes truncate to broadly triangular, 1/4 as long as the spikelets, 3-veined; lower paleas absent; upper glumes and lower lemmas equal, slightly exceeding the upper florets, 5- or 7-veined, pointed; lower florets sterile; upper florets relatively thin, smooth. 2n = unknown.
