Tufted perennial with or without short rhizomes. Culms erect, new shoots occasionally arising from lower nodes, to c. 50 cm high. Leaves cauline; blade hollow, with inconspicuous transverse septa when fresh, but more obvious when dry, shorter or longer than culms, slightly to distinctly compressed, c. 1–3 mm wide, apex acute or obtuse; auricles usually obtuse, to c. 2 mm long. Inflorescence of 2–55 close or distant clusters of 3–40 flowers, c. 6–15 mm wide in fruit; primary bract shorter or longer than the inflorescence; prophylls absent. Tepal midrib turning light brown, margins pale, membranous, reddish tinged towards apex; outer tepals (2.5–)3–4.5 mm long, acute; inner equal to or longer than outer, acute; stamens 6, anthers 0.5–0.8 mm long. Capsules light brown to golden-brown, trigonous-ovoid, c. 3.5–6.5 mm long, at maturity exceeding the tepals by at least 1 mm, tapering gradually to an acute apex; seeds 0.4–0.5 mm long, slightly asymmetrical, finely reticulate-patterned discernible at moderately high magnification, minutely apiculate at each end. Flowers mostly Nov.–Jan., seeds shed mostly Jan.–Apr.
