Description Rhizome caespitose or not, with short to very long internodes, moderately stout, dark-brown. Flowering culms (4.5)15–50(75) cm long, acutely, more rarely, obtusely trigonous, slightly scabrous at least to the apex, more rarely smooth, leafy up to ⅔ of its length, (0.4)0.6–1(1.4) mm wide at the middle. Leaves (0.4)1.5–3(5) mm wide, shorter, more rarely longer, than the inflorescence, soft to slightly rigid, straight to slightly curved at the apex, light green, flat, more rarely, scarcely carinate, in cross-section, scabrous along the margins and along the abaxial midrib to the apex; adaxial surface smooth to scarcely aculeate in some veins; ligule (0.5)1–2.5(3.5) mm long. Basal sheaths with lamina, more rarely, the lowermost bladeless, usually densely fibrous. Lowest bract of the inflorescence leaf-like, shorter, rarely longer, than the inflorescence, with a sheath (9)13–45 mm long. Inflorescence up to the upper ¾(⅘) of the length of the culm, branching up to 3 times; partial inflorescences (3)5–7(8), the (3)4–5(6) lowermost distant, pedunculate and erect, the (1)2–3 uppermost overlapping, subsessile, rarely all sessile and overlapping (in dwarf individuals). Glumiform perigynia and glumiform cladoprophylls absent. Tubular cladoprophylls always present. Utriculiform cladoprophylls rarely present. Male glumes 2–3.2 × (1.2)1.5–2.2 mm, ovate-lanceolate to widely ovate, straw-coloured to yellowish-brown, with a green central band, acute to ending in an aculeate mucro up to 0.3(0.5) mm long. Female glumes (1.9)2–3.2(3.7) × (1)1.3–1.9(2) mm, ovate, yellowish-brown, pale reddish brown or straw coloured, with a green central band, acute to ending in an aculeate mucro up to 2(6) mm long. Unisexual utricles (2)2.5–3.3(4.1) × (0.9)1.1–1.5(1.8) mm, widely ovoid to elipsoid, stipitate, straight, more rarely slightly curved, straw-coloured to brownish when mature, smooth, with conspicuous prominent veins over the entire surface, suberect to erecto-patent, abruptly contracted, very rarely attenuate, into a smooth, occasionally (some individuals from Eastern Cape) with a few, very disperse, minute prickless, asymmetrically bidentate or irregularly truncate beak (0.2)0.5–0.8(1) mm long; rachilla usually reaching the apex of the utricle, rarely protruding from it up to 0.2(0.4) mm. Bisexual utricles frequently present, widely and obliquely truncate at the apex. Achenes (1.8)1.9–2.6(2.9) × (0.8)1–1.2(1.4) mm, ellipsoid-trigonous, more or less straw-coloured to brown when mature, tipped by a very short, obtusely trigonous, sometimes slightly and shortly neck-like, rarely asymmetric, persistent style base.
