Styli basis incrassata, persistens. Stigmata 3. [details]Translation Plant apparently shortly stoloniferous, with thick woody stolons. Central culm about 70 cm tall, stout below (3 mm thick), more slender above (1.5 mm thick), distinctly though obtusely trigonous, with concave faces, straight, erect, rigid, striate, smooth, leafy except in the lower third, surrounded at the base by a few bladeless sheaths (up to 10 cm long), membranous, withered but entire, sparsely pubescent. Leaves elliptic, acuminate, shortly subpetiolate at the base, 17–22 cm long, 3–3.7 cm wide, spreading, flat, sheathing; the upper 1–4 exceeding the inflorescence, sometimes very crowded, the uppermost 1–2 bearing the lower branches of the inflorescence in their axils; many-nerved, but with the midrib and two lateral nerves stronger and more prominent, these equidistant from the midrib and margins and prominently raised together with the finer nerves; the midrib raised only on the lower surface, flat or narrowly channelled above; surfaces smooth above (except towards the apex, especially on the two lateral nerves, where scabrous), beneath all nerves appressed-hispidulous; sheaths 1.5–2 cm long, ribbed, becoming glabrescent below, hispidulous above, the mouth furnished with a thin brown ligule-like appendage. Inflorescence a compound panicle, 10–15 cm long, rather slender, erect; secondary panicles suberect, somewhat oblong, bracteate, the lower nearly fastigiate, the upper smaller, peduncles sparsely hispidulous on the angles. Rachis glabrous or sparsely hispidulous on the angles. Androgynous spikes sessile to subsessile, spreading, 8–10 mm long, few-flowered, the male part as long as the female part, at the base furnished with a rudimentary ligulate cladoprophyll about 1 mm long and ciliate. Bracts much shorter than the leaves, the lower somewhat leaf-like or herbaceous, the upper scale-like but with long scabrid awns, all usually shorter than their secondary panicles, sheathing; bracteoles scale-like, varying in size and shape, often oblong or ovate-oblong, apex usually obtuse and emarginate, margins whitish-hyaline, glabrous on the inner surface, sparsely hispidulous on the back, awned; awn hispidulous. Female scales 2–2.5 mm long, 1–1.5 mm wide, ovate or ovate-lanceolate, boat-shaped, apex somewhat acute, glabrous, finely striate, whitish-straw-colored or brownish-white, margins whitish-hyaline, erose, often mucronulate (with the midrib shortly excurrent). Utricles 4–4.5 mm long, about 1.25–1.75 mm wide, broadly ellipsoid, trigonous, spreading, glabrous, smooth, about 15–18-nerved, narrowly margined above, margins hispidulous, pale greenish-brown or bright straw-colored, very shortly stipitate, gradually contracted into a 1.5–2 mm long beak, somewhat flattened, deflexed at the base, often slightly twisted, margined, hispidulous on the margins, mouth obliquely cut and bidentate (with straight teeth). Nut tightly enclosed, rhomboid-elliptic, triquetrous, faces somewhat concave especially below, golden or light brown, very shortly stipitate, abruptly constricted below the discoid apex. Style base thickened, persistent. Stigmas 3. [details]
