Ligule an eciliate membrane; 1.5–2 mm long; 0.5 mm long on basal shoots. Leaf-blades flat, or involute; 13–20 cm long; 1–3 mm wide. Leaf-blade venation comprising 7 vascular bundles; with 7 inner ridges; with 9 subepidermal sclerenchyma strands.
INFLORESCENCE Inflorescence a panicle.
Panicle open; ovate; 7–9 cm long. Primary panicle branches 2.5–5 cm long. Panicle branches scabrous.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 8–10 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 17–18 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1 mm long; smooth.
GLUMES Glumes persistent; shorter than spikelet. Lower glume lanceolate; 2.5 mm long; 0.7–0.8 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate, or oblong; 3.5 mm long; 0.5 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume apex acuminate.
FLORETS Fertile lemma lanceolate; 6.5–7 mm long; chartaceous; without keel; 5 -veined. Lemma apex acuminate; muticous. Palea 1 length of lemma; 2 -veined. Palea keels smooth. Palea apex dentate; 2 -fid. Apical sterile florets resembling fertile though underdeveloped.
