Description Perennials. Stolons slender, often terminated by a tuber. Culms erect, grayish green, tufted, 15-60 cm tall, 1.5-3 mm thick, cylindric, smooth, glabrous, surface with transverse septa, nodes evident when dry. Leaf sheaths 2 or 3, greenish yellow, purplish red, or brown, 2-20 cm, mouth obliquely truncate, apex acute. Spikelet pale green, cylindric, 1.5-4 cm × 6-7 mm, many flowered. Basal 2 glumes empty, amplexicaul for whole spikelet base; fertile glumes grayish green, laxly imbricate, broadly oblong to ovate-oblong, 3-5 × 2.5-3.5(-4) mm, subleathery, pale brown puncticulate and finely striate, margin pale yellow and membranous, apex obtuse. Perianth bristles 7, ca. 1.5 × as long as nutlet, retrorsely spinulose. Stigmas 3. Nutlet brown when mature, broadly obovoid, ca. 2.5 × 1.8 mm, biconvex, essentially smooth but faintly and finely cancellate with hexagonal to oblong hexagonal epidermal cells, apex not constricted but with an annular thickening; persistent style base triangular-attenuate, flattened, not spongy, base ca. 1/2 as wide as nutlet. Fl. and fr. May-Oct. 2n = 38, ca. 108. [details]
