Sheaths light green to very light brown, membranous to ± coriaceous, distinctly nerved, smooth, or slightly shortscabrous to shortly hairy near ligule; ligule 0.2- 0.5 mm long, truncate in lower leaves and often very short-ciliate across top and abaxially, 1-2 mm long, smooth and rounded across top in upper leaves; lamina (1.5)-10-20-(35) cm × (1.5)-2- 4 mm, flat or folded, subcoriaceous, glabrous or sparsely finely hairy adaxially, or on both surfaces especially near ligule, margins sparsely scabrous to smooth, sometimes sparsely finely hairy near ligule, midrib scabrous near blunt, curved tip. Culms (5)-20-55cm tall, smooth. Panicle (2)-5-10- (15) cm long, ovate to pyramidal, or oblong, erect or nodding, loose and open to somewhat dense and contracted; rachis smooth, branches in clusters of 3-5, spreading, filiform, flexuous, smooth or finely scabrous with spikelets clustered at tips. Spikelets 4-6 mm long, (2)-3-6-flowered, light green or purplish. Glumes + unequal, acute, membranous, midnerve scabrous; lower glume 1.5-3 mm long, 1-3-nerved, narrow-ovate, upper 2-3.5-(4)mm long, 3-nerved, ovate-elliptic. Lemma 2.5-4 mm long, 5-(7)-nerved, ovate-oblong, subobtuse to acute, midnerve and marginal nerves thinly to densely hairy to about ½ length, finely scabrous on remainder of midnerve, internerves smooth and glabrous. Palea 2-3 mm long, smooth between finely scabrous keels. Lodicules 0.6-0.8 mm long. Callus with tuft of long crinkled hairs. Rachilla c. 0.5 mm long, smooth or very minutely sparsely papillose, projection twice as long. Anthers 1.2- 1.7 mm long. Caryopsis c. 1.5 × 0.5 mm, tightly enclosed by lemma and palea.

Rather narrow, loose to compact perennial tufts c. 10-50 cm from slender rhizomes with ± soft, bright green to greyish green leaves < culms; branching extravaginal at plant base, sometimes intravaginal above; leaf-blades persistent. Leaf-sheath light green to very light brown, membranous to ± coriaceous, distinctly ribbed, glabrous, or slightly short-scabrid to shortly hairy near ligule. Ligule in lower leaves 0.2-0.5 mm, truncate, often very short-ciliate, and abaxially minutely hairy, in upper leaves 1-2 mm, apically glabrous, entire and rounded. Leaf-blade (1.5)-10-20-(35) cm × (1.5)-2-4 mm, flat or folded, subcoriaceous, glabrous or sparsely finely hairy especially near ligule or only adaxially; margins sparsely scabrid to smooth, sometimes hairy near ligule; midrib scabrid near blunt, curved tip. Culm (5)-20-55 cm, internodes glabrous. Panicle (2)-5-10-(15) cm, ovate to pyramidal, or oblong, erect or nodding, loose and open to somewhat dense and contracted; rachis glabrous, branches in clusters of 3-5, spreading, filiform, flexuous, smooth or finely scabrid with spikelets clustered at tips. Spikelets 4-6 mm, (2)-3-6-flowered, light green or purplish. Glumes ± unequal, acute, membranous, midnerve scabrid; lower 1.5-3 mm, 1-3-nerved, narrow-ovate, upper 2-3.5-(4) mm, 3-nerved, ovate-elliptic. Lemma 2.5-4 mm, 5-(7)-nerved, ovate-oblong, subobtuse to acute, midnerve and marginal nerves thinly to densely hairy in lower ½, midnerve finely scabrid above hairs, internerves glabrous. Palea 2-3 mm, keels finely scabrid, interkeel glabrous. Callus with tuft of long crinkled hairs. Rachilla c. 0.5 mm, glabrous or very minutely sparsely papillose; prolongation twice as long. Lodicules 0.6-0.8 mm. Anthers 1.2-1.7 mm. Caryopsis c. 1.5 × 0.5 mm, tightly enclosed by anthoecium.
