Description Rhizome short, indurate. Culms loosely tufted, 15-30 cm tall, obtusely trigonous, smooth, stiff, with nodes, thickened to bulbous at base, clothed with dark brown sheaths disintegrating into fibers. Leaves longer than culm, blades narrowly linear, 2.5-3 mm wide, flattish plicate, rather stiff, slightly scabrous on margins, long sheathing. Lowest involucral bract leaflike, much surpassing inflorescence. Inflorescence long cylindric, 5-9.5 cm; spikes numerous, androgynous, ovate, 5-7 × 3-4 mm. Female glumes pale ferruginous, with brownish spots, ovate, 2.5-2.8 mm, margins white hyaline, green 3-veined costa forming a short mucro at acute apex. Utricles pale brown with dark spots, equaling or slightly longer than glume, ovate or ovate-elliptic, plano-convex, 2-2.5 × 1.8-2.5 mm, subleathery, narrowly winged, serrulate above, finely many veined abaxially, apex gradually narrowed into a beak ca. 0.3 mm, serrulate on upper margins, orifice 2-toothed. Nutlets brown, tightly enveloped, oblong-ovate, plano-convex, ca. 1.2 mm; stigmas 2. Fl. and fr. Apr-Aug. [details]
