Description Rhizomes short, woody. Culms central, caespitose, 6.5–20 cm tall, obtusely
trigonous, smooth, base with yellow-brown or dark brown fibrous sheaths. Leaves
almost equal to or shorter than culms; blades flat, 0.7–1.5 mm wide, margin slightly
revolute, scabrous, apex curved or slightly circinate. Bracts spathe-like, shorter than
inflorescence, base with 0.3–1.2 cm long sheaths. Spikes 2–4, upper ones aggregated,
sometimes with lowest one exserted from basal culms; terminal spike staminate,
oblong or clavate-cylindrical, 1.1–2 cm long, 1.5–3 mm wide, base with 0.8–1.2 cm
long peduncles; lateral spikes pistillate, oblong or ovoid, 0.6–1 cm long, 3–3.5 mm
wide, densely 7–15-flowered, peduncles erect, exserted from sheaths, 0.5–1.9 cm
long. Staminate glumes obovate, purple-black or brown, 4–4.5 mm long, apex
acute or obtuse, with pale yellow 1-veined pubescent costa excurrent into a mucro.
Pistillate glumes ovate, purple-black or brown, 2.3–2.5 mm long, apex acute or obtuse,
with yellow-brown 1- or 3-veined pubescent costa excurrent into a 0.5–1 mm long
scabrous awn. Utricles pale yellow-brown, obovoid, obtusely trigonous, 3–3.3 mm
long, membranous, obliquely patent, puberulent on upper part, laterally 2-veined,
inconspicuously thinly veined, base cuneate and shortly curved stipitate, apex abruptly
contracted into a ca. 0.3 mm long beak, orifice emarginate or obliquely truncate.
Nutlets tightly enveloped, pale yellow, obovoid, trigonous, 2.2–2.3 mm long, base
shortly stipitate, apex beakless; style base not thickened; stigmas 3. [details]
