Lax, partly sprawling and stoloniferous perennials, 18-35 cm, with sparse, narrow, soft, bright green leaves; branching extravaginal. Leaf-sheath membranous, distinctly ribbed, glabrous. Ligule 3-5 mm, oblong, erose, abaxially finely scabrid. Leaf-blade 4-15 cm × 1.5-2.5 mm, flat, thin, abaxially smooth, adaxially finely scabrid on ribs; margins finely scabrid, tip fine, subacute. Culm 7-25 cm, usually included within uppermost leaf-sheath, internodes finely scabrid below panicle. Panicle 5-20 × 1-6 cm, contracted, later spreading; branches filiform, finely scabrid, bearing few spikelets towards tip on long delicate pedicels. Spikelets 3-3.8 mm, light green. Glumes subequal, ovate-elliptic, rarely with scattered prickle-teeth near scabrid midnerve; margins hyaline, scabrid near acute tip. Lemma 1.8-2.5 mm, ± ⅔ length of glumes, faintly 3-5-nerved, glabrous, apex ± truncate and erose, lateral nerves hardly excurrent; awn 0-1.2 mm, straight, from just below lemma apex. Palea ≈ lemma, nerves very close set, apex hardly bifid. Callus hairs few, c. 0.1 mm or 0. Rachilla prolongation 0.3-0.5 mm, tipped by a few hairs to c. 0.8 mm. Lodicules linear, acute.
