Description Rhizome short; culms tufted, 25–50 cm high, 1–2.5 mm wide, triquetrous, upper part scabrid, with purple or dark brown, leafless and fibrillose sheaths at base. Leaves shorter than culms, 2–3.5 mm wide, flat, acuminate.

Female glumes narrowly lanceolate, 3.5–4 x 1 mm, dark purple, 1-nerved; utricles narrowly oblong or narrowly elliptic, 3.2–4 mm long, membranous, yellowish green to dark purple, veinless or with 3 to 5 short veins, base contracted and shortly stiped, apices attenuate, acuminate, not forming beaks, utricle mouths obliquely truncate; stigmas 3. Nutlets included in the lower part of utricle, ovate, trigonous, tiny, ca. 1.5 mm long, castaneous, sessile. [details]
