Description Perennial herb, tufts stout, rigid, spreading; occasionally shortly rhizomatous. Culms (40-)150-300(-575) × 1.5-2.0 mm, stout, ascending to spreading, trigonous, striated, smooth, rarely scabrid above, longer than, similar to, or shorter than leaves when mature. Leaves (115-) 150-300(-3 80) × 2.5-6.0 mm; leaf sheaths loose, dull brown, becoming stringy with age, nerves distinct; leaf blades channelled, occasionally double-folded, stiff, green; leaf margins and keel thickened, scabrid; apex trigonous, scabrid, acuminate. Inflorescence of 4-6(-7) densely flowered separate male and female spikes, brown, erect, borne singly at nodes, mostly sessile, closely contiguous towards the top of the culm, often lower spike remote and sometimes on a short peduncle; terminal spike male, 7.0-30 × 2.0-3.7 mm, clavate, cylindrical, brown, occasionally distal part female; remaining spikes female 6.0-35 × 5.0-7.0 mm, stout, oblong, cylindrical, brown, sometimes with a few terminal male flowers above, particularly on upper female spike. Lowermost inflorescence bract leaf-like, 60-)100-200(-350) × 2.5-5.5 mm, longer than inflorescence. Male glumes 4.0-6.4 × 1.6-2.0 mm long, speckled brown, obovate, concavo-convex, subcoriaceous, mid-region 3-veined, green fading to white at maturity; margins membranous, entire, scabrid towards apex; apex emarginate, midvein often failing, sometimes mid-vein excurrent then apex acute or shortly awned, awn scabrid. Female glumes 2.1—4.0 × 1.6-2.2 mm, shorter or similar length to utricles, speckled brown, ovate, concavoconvex, subcoriaceous, mid-region green fading
to white; margins membranous, fimbriate towards apex; apex acute sometimes shortly awned. Stamens 3, anthers 1.5-2.5 mm long. Utricles 2.5-3.7 x 1.2-2.3 mm, spreading at maturity, trigonous to subtrigonous, obovate to elliptic, sometimes slightly winged, abruptly narrowed to a distinct white beak, speckled brown to dark brown above (except for beak), usually with distinct broad, pale nerves; beak 0.4-0.5(-0.7) mm long, bidentate, white, margins occasionally scabrid; orifice slightly oblique, scabrid. Stigmas 3, 0.8-1.2 mm long. Nut 1.3-1.6 x 0.9—1.2 mm, trigonous, brown. Chromosome number 2n = c. 68 [details]
