Erect, bluish green or light green to pale brownish green, stiff, dense, very leafy tufts, (6)-10-50 cm, with uppermost leaves usually overtopping culms; branching intravaginal. Leaf-sheaths smooth, firmly membranous, finely nerved; ligule 0.6-3 mm, obtuse or truncate, or sometimes tapered at centre and acute, smooth, entire; leaf-blades 5-25 cm long, folded and then 5—10 mm wide, or sometimes almost flat, abaxially smooth, adaxially shallowly ridged and sparsely scabrous on ridges, margins scabrous, tip smooth, ± firmly acute, sometimes subobtuse and ± apiculate. Culms smooth, usually enclosed by sheaths. Panicle ± overtopped by leaves, linear-lanceolate, erect, contracted, dense; branches stiff, erect, sometimes ± spreading at maturity. Spikelets (3)-5— 9 mm, 2—5-flowered, bluish green or sometimes purplish. Glumes ± unequal, narrow-lanceolate to elliptic-oblong, subacute; lower glume 1.5—3.6-(4.2) mm, 1—3-nerved; upper glume 2-4.5—(5) mm, 3—5- nerved. Lemma 3—5 mm, 5—7-nerved, elliptic-oblong, usually with a few hairs at base and on nerves near base, sometimes with hairs on nerves to c. ½ way. Palea < or occasionally = lemma. Rachilla 0.8- 1.5-(1.8)mm. Anthers (0.6)-0.8-1.5 mm. Caryopsis (1.5)-1.8-2.6 × 0.4-0.8 mm. Endemic.

Erect, bluish green or light green to pale brownish green, stiff, dense, very leafy tufts, (6)-10-50 cm, with uppermost leaves usually overtopping culms; branching intravaginal.
