Description Rhizoma repens circiter 1.5 mm. crassum squamis tenuibus brunneis opacis tenuiter striatis obtectum. Culmi approximati vel laxe caespitosi, circiter 20–25 cm. alti, graciles flaccidulique, acute triquetri admodum compressi, scabri. Folia pauca culmum superantia, inferiora ad vaginas brunneas integras redacta, 3–4 superiora laminifera; laminae acutae, usque ad 20 cm. longae, 2–2.5 mm. latae, planae, glabrae, inferne laeves sursum nervis marginibusque scabrae, carinatae ceterum obscure nervosae. Spica unica, erecta, androgynacea, ebracteata, 10–12 mm. longa, 5 mm. crassa, oblonga, pluri- et densiflora, variegata, pars mascula linearis circiter 4–5 mm. longa. Glumae femineae ovatae acute acuminatae, 3.5–4 mm. longae, glabrae, dorso obtuse carinato 3-nerves, lateribus rubro-brunneae. Utriculi suberecti, 4.5 mm. longi, 1.2 mm. lati, membranacei, pallide viridescentes, elliptici, rostrati, acutiusculae triquetri, glabri laevesque, prominule circiter 15-nerves, basin versus angustiati brevissime stipitati, sursum in rostrum circiter 1.5 mm. longum gracile lineare triquetrum glabrum laeve ore firmo bidentatum (dentibus strictis acutis) subsensim contracti. Nux utriculo brevior et subaequilata, 1.8 mm. longa, 1.2 mm. lata, oblonga subobovoidea, obtusissima sed brevissime acuminato-apiculata, basi subacuta, valde triquetra angulis prominulis, lateribus fere plana. Stylus basi haud incrassatus; stigmata 3. [details]

Stylus basi haud incrassatus; stigmata 3. [details]Translation Rhizome creeping, about 1.5 mm thick, covered with thin, brown, opaque, finely striate scales. Culms approximate or loosely tufted, about 20–25 cm tall, slender and somewhat flaccid, sharply triquetrous, much compressed, rough. Leaves few, exceeding the culm; the lower reduced to entire brown sheaths, the upper 3–4 with blades; blades acute, up to 20 cm long, 2–2.5 mm wide, flat, glabrous, smooth below, upward rough along the nerves and margins, keeled, otherwise obscurely nerved. Spike solitary, erect, androgynous, ebracteate, 10–12 mm long, 5 mm thick, oblong, many- and densely flowered, variegated; male part linear, about 4–5 mm long. Female glumes ovate, sharply acuminate, 3.5–4 mm long, glabrous, dorsally obtusely keeled and 3-nerved, reddish brown on the sides. Utricles suberect, 4.5 mm long, 1.2 mm wide, membranous, pale greenish, elliptic, rostrate, somewhat sharply triquetrous, glabrous and smooth, prominently about 15-nerved, narrowed toward the base, very shortly stipitate, gradually contracting upward into a beak about 1.5 mm long, slender, linear, triquetrous, glabrous, smooth, with a firm, bidentate mouth (the teeth straight and acute). Nut shorter and nearly equaling the utricle, 1.8 mm long, 1.2 mm wide, oblong to subobovoid, very obtuse but shortly apiculate, base somewhat acute, strongly triquetrous with prominent angles, the sides nearly flat. Style not thickened at the base; stigmas 3. [details]
