Description Plants colonial from long-creeping rhizomes. Culms to 100 cm × (0.8–)1–1.2 mm distally. Leaves: blades flat, tip trigonous, channeled in cross section, to 40 cm × 1.5–6(–8) mm; distal leaf blade much longer than sheath. Inflorescences: blade-bearing involucral bracts 1–3, proximally blade, often sheath black, leaflike, longest 1–12 cm. Spikelets (1–)2–10, in subumbels, patent or pendent, ovoid, 10–20 mm in flower, 20–50 mm in fruit; peduncles 5–60 mm, smooth or scabrous; scales lanceolate or ovate, 5–10 mm, with prominent midrib fading proximal to tip, apex ± acute; proximal scales without lateral ribs. Flowers: perianth bristles 10 or more, white or pale yellow brown, 15–30 mm, smooth; anthers 2–5 mm. Achenes black, oblanceoloid, 2–5 mm. [details]

Description Rhizomes extensive, long-creeping. Stems 15–75 cm 1–2 mm, rather distant, erect, smooth, nodose, subterete to trigonous near apex. Leaves basal and cauline; blade 2–60 cm 2–5(–7) mm, linear, channelled, gradually narrowed to a long triquetrous apex, otherwise flat to V-shaped in cross section, yellowish- to bluish-green; sheaths up to 27 cm long (up to 8 cm on cauline leaves), ± inflated, pale to mid brown (greenish on some cauline leaves), the uppermost with a well developed blade usually at least 1.5 times as long as sheath; ligule very short, rounded. Inflorescence terminal, comprising (1–)3–7 pedunculate spikelets, ± nodding in fruit; peduncles up to 8 cm long, slender, smooth; involucral bracts 1–2, leaf-like to glume-like, sheathing, the lowest ± equalling or exceeding the lowermost spikelet. Spikelets ovoid to ellipsoid when young, soon becoming obscured by the lengthening perianth bristles. Glumes 4–10 1.5–4 mm, spirally arranged, ovate to ovate-lanceolate or lanceolate, the upper narrower than the lower, ± obtuse, membranous, 1-nerved, reddish- to greyish-brown; margins hyaline.
