Description Rhizome subwoody. Culms tufted, lateral, 30-50 × 0.1-0.2 cm, trigonous, densely hairy, base with pale brown leafless sheaths. Leaves basal and cauline; basal leaves tufted, shorter than culms, narrowly elliptic to elliptic-linear, 25-35 × 2-3 cm, scabrid abaxially, glabrous adaxially, margins entire, apex acuminate; petiole 5-15 cm, glabrous; cauline leaves spathelike, lower part green, upper part pale brown, with dense brown spots and lines, margins ciliate and glabrescent later. Involucral bracts spathelike. Panicle compound, 2-6-branched; inflorescence branches subcorymbose, single or binate, slightly distant, triangular-ovate, 1.5-2 × 2-2.5 cm; peduncles of inflorescence branches tenuous, 2-4 cm, densely hairy; inflorescence axes densely hairy; bractlets glumelike, 3-3.5 mm, densely hairy. Spikes 20 or less, bisexual, androgynous, patent, oblong-cylindric, 7-10 × 2-2.5 mm; male part of spike longer than female part, oblong, with more than 10 flowers; female part ± densely 3-10-flowered; male glumes brown, oblong, ca. 3 mm, membranous, apex obtuse; female glumes brownish white with dense brown spots and short lines, ovate-oblong, 2.5-3 mm, membranous, 1-veined, apex obtuse. Utricles pale brownish white with dense brown spots and short lines, elliptic, obliquely or horizontally patent, trigonous, ca. 3 mm, with 2 lateral veins abaxially, base obtuse, apex contracted into beak of medium length, beak slightly shorter than 1/2 length of utricle, orifice obliquely truncate. Nutlets brown at maturity, ovate, trigonous, ca. 1.5 mm; style base thickened; stigmas 3. [details]
