Description Perennial; rhizomes short, ligneous. Culms lateral, 17–25 cm tall, trigonous, glabrous, smooth, with brown coriaceous
sheaths at base. Leaves slightly shorter or longer than culms, 2.5–4 mm wide, glabrous on both surfaces, smooth, involute
at margins, glaucous abaxially. Bracts shortly leaf-like, shorter than inflorescence, sheathed at base; sheaths 5–10 mm
long. Spikes 3 or 4, upper spikes crowed, the lowest one rarely exserted at base of culms; terminal one staminate,
clavate-cylindrical, 2–2.5 cm long, ca. 4 mm wide, densely flowered, nearly sessile; lateral spikes androgynous, 1.5
2.3 cm long, slightly densely flowered, with 4–9 staminate flowers at apex, with peduncles enclosed in bract sheaths.
Staminate scales oblanceolate-elliptic, 7.5–8 mm long, acute at apex, yellowish brown at margins, brown costa 1
veined on dorsal surface. Pistillate scales ovate, 5–5.5 mm long, acuminate at apex, pale yellowish brown at margins,
green costa 3-veined on dorsal surface, exserting into a short awn at apex. Perigynia longer than pistillate scales, 7.5–8
mm long, obovoid or ellipsoid, trigonous, membranous, greenish yellow, nearly glabrous, distinctly veined, shortly
stipitate at base, contracted into a ca. 3 mm long beak at apex; orifice shortly 2-lobed with long teeth, sparsely pilose at
margins. Achenes loosely enveloped, ovoid, trigonous, castaneous, 3.2–3.5 mm long, shortly stipitate at base, abruptly
contracted into a short curved beak at apex; styles glabrous, slightly thickened at base; stigmas 3. [details]
