Description Medium-sized perennial herb, up to c. 65 cm height. Culm 25–30 cm × 2.5–3 mm. Basal leaves distichous; leaf sheaths 6–7 (–9) × c. 2 cm, brownish-purple, very wide compared to the leaf blades; leaf blades usually enrolled and thus appearing much narrower than the leaf sheaths, one to four mm wide when enrolled, up to c. seven mm when flattened, leathery, margins scabrid. Cauline leaves 1–2, five to seven mm wide margins scabrid, sheaths brownish. Inflorescence a panicle 10–35 cm long, quite tight, narrow; inflorescence bracts 5–10, brown to dark purple. Peduncles longest four to five cm, erect to arching downwards, flattened, margins scabrid. Pedicels of the spikelets erect, two to six mm, margins scabrid. Spikelets lanceolate, 6–7.5 × 1.5–2.3 mm. Glumes 5–8, the largest 5–6.5 mm long, dark purplish-brown to nearly black, the lower three to six empty, ovate, scabrid on the keel, ciliolate at the apex, increasing in length; two upper flowering glumes ovate-lanceolate. Flowers 2, lower male, upper bisexual. Perianth bristles 6, much longer than the nutlet, plumose, long ciliate. Stamens 3; anthers linear, shortly apiculate. Style trifid, long; style base hispidulous, triangular, persistent. Nutlet broad obovoid triangular, somewhat rugulose, 1.75 mm; beak one mm, almost as wide as the nutlet. [details]
