Description Root a rhizome, spreading, nodes dilated into hard tubers. Culms trigonous striate 0.3–0.9 mm. high, 2–3 mm. broad, margins scabrid above. Basal sheath pointed, brownish in older plants. Leaves cauline, grasslike, gradually tapering to a point, upper portions scabrid on midrib and margins, 2.5–4 mm. broad, 25–30 cm. long, upper leaves usually narrower than those below. Inflorescence a compact head of 3–5 spikelets with frequently 1–3 rays 10–25 mm. long subtended by 2–3 involucral bracts resembling the leaves, these bracts scabrid and unequal, the longest erect 10–22 cm. long, 1.5–2.5 mm. wide; others oblique. Spikelets ovoid to cylindric 10–20 mm. long, chestnut to brown, flowers numerous, glumes puberulent, tips cleft or lacerate, midrib produced into a somewhat scabrid awn somewhat recurved. Stamens 3, tips of anthers hispid, shortly apiculate. Styles long 2. Perianth bristles 6, unequal, retrorsely scabrid, the longest about half the nut. Achene 4 mm. long 2–3–2.5 mm. broad, lenticular or obovate, compressed, smooth, shining, shortly pointed, a depression on each side, ½ the glume, yellow to brown when ripe. [details]
