Description Rhizomes short, with loosely tufted shoots; roots pale buff-brown and grey-brown scales. Stems 20–80 cm, trigonous, solid, rough below the spikes. Leaves 10–40 cm × 1.2–3.5(–5.4) mm, usually only 1/3–1/2 as long as the stem, keeled, ± abruptly narrowed to a rough, blunt, trigonous point, mid- to yellow-green, becoming bleached straw colour and not overwintering; hypostomous; sheaths hyaline, ribbed, becoming pink-brown and fibrous, apex of inner face ± straight; ligule 1 mm, rounded, tubular. Inflorescence 1/10–1/4 the length of the stem, with bracts leaf-like or the upper glumaceous, occasionally reflexed and exceeding the inflorescence. Male spike 1, 10–20 mm, often on a conspicuous peduncle up to 28 mm long set at an angle to the flowering stem; male glumes 3–3.5 mm, lanceolate-elliptic, orange- or red-brown with green midrib, apex subacute. Female spikes 1–3(–4), densely clustered to slightly distant, 8–15 mm, ovoid to cylindrical, sessile or with the lowermost on a short ensheathed peduncle; female glumes 2.5–4 mm, ovate-lanceolate, orange- or red-brown with green midrib and often hyaline margin, apex acute, falling before the utricle. Utricles 3–5.5 mm, obovoid-trigonous, ribbed, yellow-green, patent, the lower deflexed; beak 1.5–2 mm, split, arcuate or deflexed in side view; stigmas 3; nut obovoid, trigonous. [details]
