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.. Leaf-blades 6–20 cm. long, 2–6 mm. wide.. 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.. 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.. Pedicelled spikelet glabrous.
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.
Perennial 300-700 mm high, often stoloniferous; aromatic. Leaf blade 60-200 x 2-6 mm; ligule a fringed membrane, hairs shorter than membrane. Inflorescence axis shorter than racemes, racemes 5-16. Sessile spikelet 2.5-5.0 mm long; lower glume sparsely hairy, without pits; anthers 1.0-1.5 mm long. Pedicelled spikelet 3.0-3.5 mm long.
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.
Perennial; up to 0.7 m high; often stoloniferous. Leaf blades 60-200 x 2-6 mm. Flowers: inflorescence subdigitate; axis shorter than racemes; racemes 5-16; spikelets (sessile) 3-5 mm long; lower glume of sessile spikelets sparsely hairy; not pitted.
