Description
Soft, ± drooping, light green stoloniferous perennial tufts, c. 20–60 cm, rooting at nodes; branching extravaginal; leaf-blades persistent. Leaf-sheath light green to light brown, submembranous, distinctly ribbed, glabrous. Ligule 1–4.5 mm, entire, apically glabrous, gradually narrowed and subacute, abaxially slightly scabrid. Leaf-blade 7.5–25 cm × 2–4.5 mm, flat, soft, smooth almost throughout but minutely scabrid abaxially near straight-sided narrow acute tip and adaxially just above ligule. Culm (8)–18–50 cm, internodes glabrous. Panicle 5–15 cm, ± lax and usually open with spreading branches; rachis usually ± smooth, branches ± smooth to sparsely scabrid. Spikelets 4–6 mm, (2)–3–4-flowered, brownish green. Glumes ± unequal, narrow-lanceolate, acute to acuminate, glabrous, apart from a few prickle-teeth on midrib in upper ½; lower 1.5–3 mm, 1-nerved, upper 2–3.5 mm, 3-nerved. Lemma 2.5–5 mm, 3–(5)-nerved, ± elliptic, acute, with long hairs on lower ½ of midnerve and at base of lateral nerves and fine prickle-teeth on midnerve above, internerves glabrous or sometimes slightly scabrid near tip. Palea 2–4 mm, keels shortly ciliate-scabrid, interkeel glabrous. Callus with narrow tuft of long fine hairs. Rachilla 0.5 mm, glabrous; prolongation twice as long. Lodicules 0.4–0.5 mm. Anthers 0.5–1 mm, mainly pollen-sterile. Caryopsis not seen.
