INFLORESCENCE Inflorescence composed of racemes.

Racemes 1; single; bilateral; 8–15 cm long; 10 mm wide. Rhachis tough; flattened. Spikelet packing broadside to rhachis. Rhachis internodes oblong.

Spikelets solitary. Fertile spikelets sessile.

FERTILE SPIKELETS Spikelets comprising 2 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 7–9 mm long; persistent on plant.

GLUMES Glumes similar; shorter than spikelet. Lower glume oblong; 7–9 mm long; 1 length of upper glume; coriaceous; 1-keeled; keeled above; 5–9 -veined. Lower glume apex awned; 1 -awned. Lower glume awn 10–30 mm long. Upper glume oblong; 7–9 mm long; 0.9–1 length of adjacent fertile lemma; coriaceous; 1-keeled; keeled above; 5–9 -veined. Upper glume lateral veins divergent at apex. Upper glume awned; 1 -awned. Upper glume awn 10–30 mm long.

FLORETS Fertile lemma elliptic; 7–9 mm long; coriaceous; without keel; 9–11 -veined. Lemma apex awned; 1 -awned. Principal lemma awn 30–50(–100) mm long overall. Palea 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.

FLOWER Anthers 3. Ovary with a fleshy appendage below style insertion; pubescent on apex.
