Description

Habit: Perennial; caespitose. Culms erect, or geniculately ascending; 30-75 cm long. Culm-nodes pubescent. Leaf-sheaths outer margin hairy. Leaf-sheath oral hairs lacking. Ligule an eciliate membrane, or a ciliolate membrane; 0.2-1.5 mm long. Collar pilose, or bearded. Leaf-blades flat, or convolute; 7-20 cm long; 2-6(-8) mm wide. Leaf-blade surface hispid; hairy adaxially, or on both sides. Inflorescences: Inflorescence a panicle. Panicle contracted; linear; 6-15 cm long. Primary panicle branches bearing spikelets almost to the base. Spikelets in pairs. Fertile spikelets pedicelled. Pedicels unequal. Spikelets: Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 3-4.5 mm long; falling entire. Spikelet callus pilose; base obtuse. Spikelet callus hairs 0.3-1 mm long. Fertile Spikelets: Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 3-4.5 mm long; falling entire. Spikelet callus pilose; base obtuse. Spikelet callus hairs 0.3-1 mm long. Glumes: Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 3-4.5 mm long; 1.1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume surface scabrous; rough on veins. Lower glume apex acute, or acuminate; muticous, or awned; 1 -awned. Lower glume awn 0-7 mm long. Upper glume lanceolate; 2.8-4.2 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute, or acuminate; muticous, or awned; 1 -awned. Upper glume awn 0.7 mm long. Florets: Fertile lemma oblong; 2.8-4.2 mm long; cartilaginous; without keel; 3 -veined. Lemma surface glabrous, or pubescent; hairy at base. Lemma margins involute; interlocking with palea keels. Lemma apex awned; 1 -awned. Principal lemma awn straight, or flexuous; 6-15(-20) mm long overall; without a column. Palea with auriculate flaps; 1 length of lemma; cartilaginous; 2 -veined. Palea keels winged (below); narrowly winged. Flowers: Lodicules 2; cuneate; fleshy. Distribution: Asia-temperate: China and eastern Asia. Asia-tropical: India and Malesia. Pacific: north-central.

Perennials; culms tufted, erect or decumbent, 3-5 dm tall, glabrous. Sheaths glabrous or villous on margins and sparsely so at throat and on collar; ligule a ciliolate membrane less than 1 mm long; blades flat, becoming involute toward apex upon drying, 5-15 cm long, less than 5 mm wide, upper surface sparsely scabrous, lower surface glabrous, apex long-acuminate, base narrowed. Panicles narrow, moderately dense, 7-15 cm long, the branches appressed; spikelets subterete, in pairs appressed along the branches, pedicels angled, scabrous, thickened upward, the shorter pedicel 1-2 mm long, the other pedicel 2-4 mm long, the base of the spikelet stiffly pubescent with hairs ca. 0.5 mm long; glumes firm, ca. 4 mm long, 3- nerved, scaberulous on the nerves and somewhat so on the back, first glume with an awn ca. 5 mm long, second glume depressed or flat on the back, with an awn ca. 2 mm long; lemma firm, 3-4 mm long, slightly shorter than glumes, nerves faint, glabrous, rounded and somewhat depressed on the back, sparsely pilose near margins at base, apex prolonged into a scabrous awn ca. 10 mm long; palea about as long as lemma, faintly 2-nerved, hyaline, apex with a minute tuft of hairs. Caryopsis pale brown, narrowly ovoid to fusiform, slightly dorsally compressed, 1.3-1.8 mm long. [2n = 20.]
