HABIT Perennial; caespitose. Basal innovations intravaginal. Culms erect; 25–45 cm long. Lateral branches lacking. Leaf-sheaths open for most of their length. Ligule an eciliate membrane. Leaf-blades filiform; conduplicate; elliptic in section; 2–10 cm long; 0.6–1.1 mm wide; stiff; mid-green, or glaucous; without exudate. Leaf-blade venation comprising 7 vascular bundles; with 3 inner ridges; with 3 subepidermal sclerenchyma strands; without layer of subepidermal sclerenchyma masking vein striation, or with unevenly thickened subepidermal sclerenchyma layer on the underside, or with continuous uniform subepidermal sclerenchyma layer on the underside. Leaf-blade apex acute.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear; 3–5.5 cm long.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 3–5 fertile florets; with diminished florets at the apex. Spikelets elliptic, or oblong; laterally compressed; 5.6–7.5 mm long; breaking up at maturity; disarticulating below each fertile floret.

GLUMES Glumes persistent; dissimilar; shorter than spikelet. Lower glume lanceolate; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate, or ovate; chartaceous; without keels; 3 -veined. Upper glume apex acute.

FLORETS Fertile lemma lanceolate; 4–4.9 mm long; chartaceous; shiny; without keel; 5 -veined. Lemma surface glabrous. Lemma apex acute; muticous, or awned; 1 -awned. Principal lemma awn 0–0.8 mm long overall. Palea 2 -veined. Apical sterile florets resembling fertile though underdeveloped.
