Leaf-sheaths tubular for much of their length; with 0.8 of their length closed; glabrous on surface. Ligule an eciliate membrane. Leaf-blades filiform; conduplicate; elliptic in section; 20–25 cm long; 0.4–0.5 mm wide. Leaf-blade venation comprising 5 vascular bundles; with 1(–3) inner ridges; with 3 subepidermal sclerenchyma strands; without layer of subepidermal sclerenchyma masking vein striation. Leaf-blade surface glabrous.
INFLORESCENCE Inflorescence a panicle.
Panicle contracted; 5–6 cm long. Panicle axis scabrous. Panicle branches scabrous.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 4–5 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 5.5–6.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; chartaceous; without keels; 3 -veined. Upper glume apex acuminate.
FLORETS Fertile lemma oblong; 3.5–4 mm long; chartaceous; without keel; 5 -veined. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn 1.6–2 mm long overall. Palea 2 -veined. Palea keels scaberulous; adorned above; with 0.33 of their length adorned. Apical sterile florets resembling fertile though underdeveloped.
