Culms loosely tufted, (25–)30–50(–70) cm tall, erect or obliquely ascending, soft and slender, scabrid, rarely smooth below inflorescence, nodes (2–)3 or 4, uppermost up to 1/3(–1/2) way up culm. Shoots extravaginal. Leaf sheaths scabrid, long, the uppermost only 2–5 cm shorter than internode and usually shorter than blade; leaf blades flat, very thin and soft, (4–)6–12 × 0.1–0.15(–0.2) cm; ligule (2–)3–5(–8) mm. Panicle narrow, congested to loose, (4–)6–12 × 1–1.5(–2) cm, branches erect, 2–5 per node, basal ones 1/3–1/2 as long as panicle with spikelets distally crowded. Spikelets lanceolate, sometimes very narrow and elongated, green or bluish, 3.5–5(–8) mm long, florets 2–5; rachilla glabrous or pubescent; glumes narrowly lanceolate, unequal, 2.5–4(–4.5) mm; lemma lanceolate, sometimes very narrow, (2.5–)3–4 mm, rarely pubescent between veins, apex membranous; callus sparsely webbed (rarely glabrous).
