INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear; 6–15 cm long. Primary panicle branches appressed; bearing spikelets almost to the base.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 3.5–4 mm long; falling entire. Spikelet callus glabrous; base obtuse.

GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 3.5–4 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume apex acuminate; muticous, or mucronate. Upper glume lanceolate; 3.5–4 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute, or acuminate.

FLORETS Fertile lemma oblong; 3.5–4 mm long; cartilaginous; without keel; 3 -veined. Lemma margins involute; interlocking with palea keels. Lemma apex acuminate; muticous, or awned; 1 -awned. Principal lemma awn straight; 0–1.8 mm long overall. Palea with auriculate flaps; 1 length of lemma; cartilaginous; 2 -veined. Palea keels winged (below); narrowly winged.
