Description Perennial evergreen herbs. Rhizomes short, densely caespitose. Culms 15–60 cm tall, slightly longer than leaves, acutely trigonous, smooth. Leaves basal and cauline; blades flat, 1.5–3 mm wide, stiff, smooth; basal sheaths with leaf blades, dark brown, fibrillose. Flowers September to October. Inflorescence terminal, racemose, with 3–6 spikes on upper 1/5 to 1/3 of the culm, solitary (rarely 2) at node; spikes androgynous, staminate section shorter than
pistillate one, lower spikes sometimes branching, narrowly cylindrical, 1–2.5 cm long, ca. 2 mm wide, subdensely many-flowered. Bracts leaf like, with sheaths, upper blades short, lower blades longer than spikes. Pistillate scales elliptic, shorter than perigynia, 1.5–2 mm long, obtuse to acute, brownish. Perigynia erect to ascending, elliptic, biconvex, 2.5–3 mm long, ca. 1 mm wide, membranaceous, finely several veined, glabrous, shortly stipitate, stipe ca. 0.3 mm long, suddenly narrowed apically to beak, beak to 1 mm long, apex bidentate. Achenes tightly enveloped in the perigynia, elliptic, biconvex, ca. 1.5 mm long, ca. 0.8 mm wide, dark brown or black at maturity. Styles to 1 mm long, base thickened. Stigmas 2, 2–3 mm long, caducose. [details]
