Cool season, annual reeds. Stems scattered or in dense stands, rooting in mud, 1–3 m; sheath essentially hairless with overlapping margins; collar hairy; ligule membranous, 10–15 mm long. Leaves: blades 1–4 cm broad, flat and ascending. Inflorescences of large open panicles, 4–6 dm in length, the lower branches bearing pendulous staminate spikelets, the upper bearing appressed-ascending pistillate spikelets. Spikelets with one floret; staminate 6–8 mm long, pistillate 10–15 mm long (to 20 mm long in fruit), nearly round in cross-section, glumes of both spikelet types minute and consisting of a small cup just below point of disarticulation. Lemmas of pistillate spikelet hispid toward tip and tapered to an awn 6–40 mm long. Lemmas of staminate spikelets thin-textured and ephemeral. Disarticulation above glumes; unit of disarticulation the floret and fruit (Lavin in Lesica et al. 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
