INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear; 4–8 cm long. Primary panicle branches appressed; bearing spikelets almost to the base.

Spikelets solitary. Fertile spikelets pedicelled.

GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 3–3.5 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn 1.5–3 mm long. Upper glume lanceolate; 3–3.5 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex emarginate, or acute; muticous, or mucronate.

FLORETS Fertile lemma oblong; 3–3.5 mm long; cartilaginous; without keel; 3 -veined. Lemma margins involute; interlocking with palea keels. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn curved; 4–6 mm long overall. Palea with auriculate flaps; 1 length of lemma; cartilaginous; 2 -veined. Palea keels winged (below); narrowly winged.
