Perennial with short rhizome. Stems tufted, com-pressed-trigonous, striate, glabrous or sparsely soft-hairy, few-leaved at the base, 30-40 cm by ½-1 mm. Leaves half as long as the stems, rather stiff, curved, flat, rather abruptly acuminate, densely hairy in the lower part, scabrid on the margins, 1½-2 mm wide; sheaths pale, densely hairy in the upper part; ligule a dense fringe of hairs. Inflorescence simple or compound, loose, with 4-10 spikelets, 2-5 cm long. Involucral bracts up to 5, the lowest shorter than to as long as the inflorescence. Primary rays few, compressed, smooth and glabrous, 2-4 cm. Spikelets solitary, oblong-ovoid, terete, acute, many-flowered, 7-10 (ultimately up to 14) by 2½-3 mm; rachilla narrowly winged. Glumes spiral, membranous, oblong-ovate, rather acute, apiculate or mucronulate, scarcely keeled, glabrous, distinctly many-nerved almost over the whole breadth, brown, 3-4½ by 1½-3 mm. Stamens 3; anthers linear, 1½-1¾ mm, with distinctly produced, papillose-setulose append-age of the connective. Style flat, rather broad, slightly dilated at the base, densely ciliate in the upper half, 2-2½ mm; stigmas 2, about as long as the style. Nut turgidly biconvex, with obtuse edges, oblong-obovate, broadly stipitate, umbonulate, re-ticulate by the roundish or transversely elliptic, slightly impressed epidermal cells superposed in 12-16 vertical rows on either face, greyish brown, 1¼-1½ by 7/10-9/10 mm.
