Culms densely tufted, 7–15(–25) cm tall, pale, glabrous or slightly scabrid under the panicle, nodes 2, both near culm base. Shoots usually intravaginal. Leaf sheath usually slightly scabrid, uppermost 1/2 as long as internode; blade folded or inrolled to needle-shape, firm, usually up to 1/2 as long as sheath, 0.3–0.8(–1.5) mm wide, scabrid; ligule 1.5–2.5 mm. Panicle dense, contracted to spiciform, a bit more open at anthesis, 1.5–4 × 0.4–1 cm; branches 2 or 3 per node, 1/5–1/3 as long as panicle. Spikelets lanceolate, (2.5–)3–4.5(–5) mm, florets 2 or 3(–5); rachilla warty; glumes shorter than spikelet, usually equal to first lemma, lemma (2.5–)3–3.5 mm, keel shortly villous for 1/2 of length, marginal veins for 1/3, other parts glabrous; callus webbed or glabrous; palea glabrous between veins. Anthers 1.2–1.5 mm. Fl. Jun–Aug.
