Open tufts, rather stiffly erect; leaves about ½ length of culms to only slightly shorter; new shoots extravaginal. Sheaths brownish or often purpled above, glabrous or long-hairy; collar hairs 1.5-2.5 mm long; ligule ± 0.2 mm long; lamina to 15-(20) cm long, usually folded, sometimes flat with inrolled margins, to 2 mm wide, glabrous or often with few scattered long hairs near collar, sometimes almost all leaves with some long hairs, margins occasionally finely scabrous. Culms up to 30-(50) cm tall, glabrous, minutely scabrous below inflorescence. Panicle usually erect, dark purple, up to 3.5—(8.5) cm long; rhachis and pedicels densely but shortly scabrous, often with very slightly longer hairs above branch axils. Spikelets 3-(4)-flowered, awns exserted from glumes. Glumes usually dark purpled centrally, lanceolate, acute to acuminate, 6.5-9 mm long, ± equal, 3-(5)-nerved. Lemma 1.5-2.5 mm long, 9-nerved, upper row of hairs continuous, > or ± = lemma lobes, lower row of marginal tufts and a few weak central tufts, or ± continuous, elsewhere predominantly glabrous, occasionally with some few isolated hairs between rows, margins hair-fringed; lemma lobes 2.7-3.5 mm long, tapering, awnless or very finely awn-tipped. Central awn 6-8.5 mm long; column 1-1.5 mm long, > or ± = palea, < upper lemma hairs. Palea 2.5-3 mm long, much < upper lemma hairs, glabrous or occasionally with 1-2 long hairs between keels and on margins. Callus 0.2-0.3- (0.5) mm long, with a few short scattered marginal hairs not, or barely, reaching lower lemma hairs. Rhachilla 0.8-1.2 mm long. Anthers 0.5-0.8- (1.1) mm long. Caryopsis 1.1-1.3 × 0.6 mm;embryo 0.5-0.7 mm long; hilum 0.2-0.3 mm long. Endemic.
