INFLORESCENCE Inflorescence composed of racemes.

Racemes (1–)2–3; paired, or digitate; straight, or sinuous; unilateral; 4–9 cm long. Rhachis flattened, or angular; glabrous on margins, or ciliate on margins. Spikelet packing crowded; regular; 2 -rowed.

Spikelets appressed; solitary. Fertile spikelets pedicelled. Pedicels cuneate; flattened.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; compressed strongly; 2.5–3.5 mm long; falling entire. Spikelet callus glabrous to pilose; base truncate.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume elliptic; 1 length of spikelet; coriaceous; 1-keeled; winged on keel; winged narrowly; winged above; 3 -veined. Lower glume primary vein eciliate, or ciliate. Lower glume apex acute. Upper glume oblong; coriaceous; with hyaline margins; 1-keeled; winged on keel; winged all along; 3 -veined. Upper glume primary vein ciliate. Upper glume apex obtuse, or acute.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; 2.5 mm long; hyaline; ciliolate on margins. Fertile lemma elliptic; 2.5 mm long; without keel; 1 -veined. Lemma apex dentate; 2 -fid; muticous, or mucronate. Principal lemma awn from a sinus; straight; 0–3 mm long overall. Palea absent or minute.
