Caespitose, often stoloniferous, perennial, shrubby or decumbent and rooting at the nodes; culms up to 70 cm high, branching from the inferior nodes to form cushions; culm nodes mostly exposed and barbate, the uppermost glabrous; leaf sheaths glabrous except at the mouth, those of the basal leaves loose and open, the remainder clasping the culms; ligule membranous; leaf laminas 6–20 cm × 2–6 mm, linear-lanceolate, gradually tapering to a fine point.
Sessile spikelet 2.5–4 mm long, lanceolate; inferior glume firmly membranous, slightly concave on the back and pilose in the lower half; superior glume minutely hispid along the keel, acute at the apex; inferior floret empty, the lemma c. 3 mm long, oblong-linear, ciliolate at the apex; superior floret bisexual, epaleate, the lemma c. 1.5 mm long, stipitiform, glabrous, awned; awn c. 25 mm long, geniculate; anthers c. 1.5 mm long.
Inflorescence of 5–16 subdigitate racemes; main axis slender, shorter than the lowest racemes; racemes up to 70 mm long, 10–20-jointed, shortly pedunculate; rhachis internodes densely long-pilose.
Pedicelled spikelet neuter; inferior glume c. 3.5 mm long, oblong, with sparse long white hairs along the lateral keels and ciliolate towards the apex; superior glume c. 3 mm long, lanceolate, delicate, ciliate on the margins; inferior lemma c. 2 mm long, oblong, obtuse at the apex.
Sessile spikelet lanceolate, 2.5–4 mm. long; lower glume firmly membranous, pilose below the middle, not glossy, not pitted; awn 10–25 mm. long.
Inflorescence subdigitate or with a central axis up to 5 cm. long, bearing 5–16 sessile or shortly pedunculate racemes; racemes 3–7 cm. long, villous.
Leaf-blades 6–20 cm. long, 2–6 mm. wide.
Perennial with copious, often fasciculate, branching from lower nodes to form cushions; culms 25–100 cm. high, usually ascending, the nodes nearly always pubescent to bearded.
Perennial, often stoloniferous, up to 0.7 m high. Leaf blades 60-200 mm long, 2-6 mm wide. Spikelets (sessile) 3-5 mm long. Inflorescence axes shorter than racemes, racemes 5-16, lower glume of sessile spikelets sparsely hairy, glumes not pitted.
