Ligule an eciliate membrane; 2–4 mm long; truncate. Leaf-blades 10–18 cm long; 3–6 mm wide. Leaf-blade surface scabrous; rough abaxially; pilose; sparsely hairy; hairy adaxially. Leaf-blade apex acuminate.

INFLORESCENCE Inflorescence a panicle. Peduncle scaberulous above.

Panicle open; lanceolate, or ovate; 9–18 cm long; 3.5–6 cm wide. Primary panicle branches ascending, or spreading; 2–3 -nate; 7–8 cm long. Panicle branches capillary.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; curved; 3–7 mm long.

FERTILE SPIKELETS Spikelets comprising 2–3 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 8–12 mm long; falling entire.

GLUMES Glumes similar; with lower wider than upper; shorter than spikelet; thinner than fertile lemma. Lower glume oblong, or ovate; 8–11 mm long; 1 length of upper glume; scarious; much thinner above; much thinner on margins; without keels; 5–7 -veined. Lower glume apex obtuse. Upper glume oblong, or ovate; 8–11 mm long; 1 length of adjacent fertile lemma; scarious; much thinner above; with hyaline margins; without keels; 5–7 -veined. Upper glume apex obtuse.

FLORETS Fertile lemma ovate; 9–11 mm long; chartaceous; much thinner above; much thinner on margins; without keel; 7–9 -veined. Lemma surface hispid; hairy below. Lemma apex obtuse. Palea 2 -veined. Palea keels eciliate, or ciliolate. Apical sterile florets barren; in a clump; ovate; 2 mm long. Apical sterile lemmas acute.

FLOWER Lodicules 2; united; oblong; fleshy; truncate. Anthers 3; 1.5–2 mm long.

FRUIT Caryopsis with adherent pericarp. Hilum linear; 0.66–0.75 length of caryopsis.
