Leaf-sheaths without keel, or keeled; outer margin hairy. Leaf-sheath oral hairs lacking, or ciliate. Ligule a ciliate membrane. Leaf-blades conduplicate, or involute; 20–60 cm long; 2–4 mm wide.

INFLORESCENCE Inflorescence a panicle.

Panicle contracted; linear, or lanceolate; 25–90 cm long. Primary panicle branches appressed; bearing spikelets almost to the base. Panicle branches stiff.

Spikelets solitary. Fertile spikelets pedicelled.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 4–7 mm long; falling entire. Spikelet callus pilose; base obtuse. Spikelet callus hairs 0.5–1 mm long.

GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 4–7 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume apex acute to setaceously attenuate. Upper glume lanceolate; 4–7 mm long; 2 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute to setaceously attenuate.

FLORETS Fertile lemma oblong; 2–4 mm long; cartilaginous; dark green, or dark brown; without keel; 3 -veined. Lemma margins involute; interlocking with palea keels. Lemma apex dentate; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 5–8 mm long overall; with twisted column. Palea with auriculate flaps; 1 length of lemma; cartilaginous; 2 -veined. Palea keels winged (below); narrowly winged.
