Inflorescence of 1[–3] spikelets, c. 2 cm long; lowest involucral bract 0.1–0.2 cm long. Spikelets narrow-ovate, acute, 1–3-flowered, Glumes 5–8, lowest 3–5 empty, ovate to narrow-ovate, acute, straw-coloured to red-brown or blackish, evenly coloured or patchy, ± shining, with margins usually ciliate at apex and glabrous below; fertile glumes 13–16 mm long; anthers 6.3–9 mm long excluding apical appendage 0.8–1.8 mm long. Hypogynous scales obtuse or rarely acute, very broad, scarcely reaching to top of stipe.
