Ligule an eciliate membrane. Leaf-blades 10–25 cm long; 3–6 mm wide. Leaf-blade surface pubescent; hairy on both sides.

INFLORESCENCE Inflorescence a panicle.

Panicle open; linear; 10–18 cm long. Primary panicle branches indistinct the panicle almost racemose; bearing 1 fertile spikelets on each lower branch.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 7–11 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or oblong; laterally compressed; (15–)20–25 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.

GLUMES Glumes persistent; shorter than spikelet. Lower glume lanceolate; 7–10 mm long; 0.75 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface pubescent. Lower glume apex acute. Upper glume lanceolate; 9–14.5 mm long; 0.8 length of adjacent fertile lemma; membranous; without keels; 3–5 -veined. Upper glume surface pubescent. Upper glume apex acute.

FLORETS Fertile florets divergent. Fertile lemma lanceolate, or oblong; 11–16 mm long; chartaceous; without keel; 5–7 -veined. Lemma surface pubescent. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn subapical; 1.5–6 mm long overall. Palea 1 length of lemma. Palea keels ciliolate. Palea surface pubescent; hairy on back. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Lodicules 2; membranous. Anthers 3; 3–7 mm long. Ovary with a fleshy appendage above style insertion; pubescent on apex.

FRUIT Caryopsis with adherent pericarp; hairy at apex; apex fleshy. Hilum linear.
