Depth range Perennial herbs. Rhizomes tufted rarely shortly ascending in large plant. Culms central and lateral, many, obtusely trigonous, 30–55 cm tall, 1–2 mm thick. Leaves linear as long as culms, (3–)3.5–5 mm wide, basal sheaths light brown. Inflorescence racemose; terminal spike staminate and lateral spikes pistillate with leafy bract sheathing at the base. Staminate spike solitary, linear, (10–)15–25 mm long, 1 mm thick, pale green. Staminate scales 3-nerved, pale green with greenish center, oblong, acute, (3.3–)3.5–4.5(–4.7) mm long. Stamens 3. Pistillate spikes (3–)4–5, oblong to linear 152 (12–)15–30(–35) mm long, 2 mm thick, Full green. Pistillate scales 3-nerved, pale green with greenish center, obovate, shortly aristate, (1.9–) 2.0–2.5(–2.6) mm long excluding awn (awn 0.2–0.5 mm long). Perigynia obovate, glabrous, 10–13-nerved, membranous, subabruptly tapering to shortly bidentate beak, 2.5–3.2 mm long, dull green. Achenes light brown, three ridged, oblong, wrinkled at the middle of three faces, 1.6–2.0(–2.1) mm long, 0.8–0.9 mm wide; stipes usually straight to the base; base of style
with an appendage; silica bodies on epidermal cells concave with well developed central body and sinuate anticlinal wall. Stigmas 3 [details]
