Description Perennial, with long rhizomes. Stems 19–25 cm long, 0.6 mm wide below the inflorescence, obscurely trigonous, almost cylindrical, sulcate, smooth. Leaves basal and cauline, shorter than stems, the uppermost ones up to 7.5–15 cm long, the widest ones 2.6–4.3 mm wide, flat or slightly incurved outwards, apparently hypostomatic, antrorsely scabrid on edges; ligule of cauline leaves 2–12 mm, pale orangey to yellowish or whitish, acute; basal sheaths creamy, sometimes red-brownish tinged, bladeless, splitting in fibers. Inflorescence 4–10 cm, with 3–5 (often 4) spikes, the uppermost gynecandrous, the other female, loosely disposed at the top of the stems; lowermost bract shortly leafy to setaceous, shorter than the inflorescence 1.3–5.5 cm × 0.5–1 mm, flattish, with a sheath (0.5)1–2 cm long; second owermost bract setaceous, shorter than its spike, sheathless. Uppermost spike 17–25 × 6–7 mm, subclavate, with the male and female parts subequal in length, with a peduncle 2–8 mm long. Lateral spikes 12–33 × 3–5 mm, narrowly obovate, dense, the lowermost with a peduncle 2.2–3 cm long, flexuous or suberect, utricles ascending, 15–45. Glumes 3.5–4.5 × 1.2 mm, obovate to narrowly obovate, dark purplish with a greenish midrib, obtuse, scabrid at the tip on the margins and midrib. Stigmas 2. Utricles 4.5–5 × 1.2–1.5 mm, elliptical, flattish, with only the two lateral nerves prominent, sparsely hairy, yellowish, progressively becoming purplish on the abaxial side from the upper half or the upper third up to the beak, but keeping lateral nerves always yellowish, gradually attenuated into a beak 1.2–1.5 mm
long, linear, flattish, scabrid, bidentate. No ripe achenes found, the inmature achenes studied conspicuously stipitate, with a stipe ca. 0.5 mm long. [details]
