Branch complement one; solitary; as thick as stem. Leaves 3–5 per branch. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs setose; spreading. Ligule an eciliate membrane. Leaf-blade base with a brief petiole-like connection to sheath. Leaf-blades oblong; 5–10 cm long; 10–25 mm wide; dark green and light green; discolorous with last colour beneath.

INFLORESCENCE Inflorescence a panicle.
Panicle open; oblong, or ovate; 6–9 cm long.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 3–7 fertile florets; with diminished florets at the apex. Spikelets linear, or oblong; laterally compressed; 25–40 mm long; 9–18 mm wide; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes eventually visible between lemmas; pilose.
GLUMES Glumes persistent; dissimilar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate. Lower glume apex acute. Upper glume ovate. Upper glume apex acute.
FLORETS Fertile lemma ovate; 6–11 mm long; chartaceous; without keel. Lemma margins ciliolate. Lemma apex acute. Palea 5–10 mm long. Palea keels ciliolate. Palea apex dentate; 2 -fid. Apical sterile florets resembling fertile though underdeveloped.
