Description Loosely cespitose from short, ascending rhizomes 2–3.5 mm thick, rhizomes ca. 0.5–2 cm long between shoots, rhizome scales brown, disintegrating into coarse fibers; culms 20–90 cm tall, stiffly erect, bluntly trigonous, very finely papillose, 0.6–1.1 mm wide immediately below the inflorescence; phyllopodic, cataphylls and basal sheaths brown, the youngest usually reddish-purple. Leaves ca. 6–12, essentially basal; blades 3.5–48 cm long, 1.5–4 mm wide, much shorter than culms, ±folded, margins and midrib smooth to finely antrorsely scabrous distally, ±smooth adaxially, papillose abaxially; leaf sheaths 1.5–15 cm long, glabrous, ventrally whitish or pale brown, hyaline, thin, concave at the apex; ligules ca. 0.8–5.5(–7.5) mm long, acute to rounded, slightly shorter than to longer than wide, the free portion whitish to pale brown. Inflorescences 3–9.5 cm long, with 3–5(–6) spikes, terminal staminate or sometimes gynaecandrous, laterals pistillate; upper lateral spikes ±overlapping, lower sometimes separate, lower two spikes 0.7–4.5 cm distant, lowermost ±sessile or on a ±smooth peduncle up to 14.2 mm long; lowest bracts ±bristle-like up to 7.5 cm long and 1.5 mm wide, sheathless, upper bracts abruptly reduced. Terminal spike (6.5–)11.5–27 mm long, pistillate portion (0–)2.5–10 mm long, 4.5–7.2 mm wide, ca. (0–)1–28-flowered, staminate portion 4.5–26.5 mm long, 1.8–3.5 mm wide, ca. 10–65-flowered, peduncle 1.8–38 mm long. Lateral spikes 4–22 mm long, 4–6.8 mm wide, short-cylindric, densely flowered with ca. 5–45 spreading-ascending perigynia. Staminate scales 2.5–4.1 mm long, 1.4–2.4 mm wide, ovate to obovate, reddish-brown with broad hyaline margins, apex obtuse to rounded, with a green, 1–3-nerved center. Pistillate scales 1.6–2.5 mm long, 1.5–2.2 mm wide, reddish-brown to reddish-purple, with broad hyaline margins, broadly ovate to ±circular, obtuse to rounded, green 1–3-nerved center rarely prolonged into a scabrous-ciliate apiculus or awn up to 0.4 mm long. Perigynia 2.5–3.3 mm long, 1.5–2.3 mm wide, rounded trigonous to plumply biconvex, broadly obovate, essentially filled by the achene, coriaceous, finely papillose distally, green to reddish-brown distally, greenish proximally, 2-nerved and sometimes with a few faint nerves on the faces, rounded-tapering to a ±sessile base, contracted into a well-defined cylindrical beak; beaks 0.25–0.5 mm long, finely papillose and sometimes setulose, green to brown, the apex ±erose to obscurely bidentulate with teeth up to 0.2 mm long. Achenes 1.7–2.4 mm long, 1.3–1.6 mm wide, concavely tapering to a thick stipe 0.1–0.2 mm long, flattened-trigonous in cross section; convex sides narrowly elliptic to obovate, brown, smooth; apex usually apiculate with an apiculus up to 0.2 mm formed by the persistent style base; style deciduous; stigmas 3. Anthers 3, 1.7–3 mm long, with an apiculus ca. 0.1 mm long. [details]
