INFLORESCENCE Inflorescence a panicle.

Panicle open; pyramidal; effuse. Panicle branches capillary.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; laterally compressed; 1.5–2 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus pubescent; obtuse.

GLUMES Glumes persistent; exceeding apex of florets; thinner than fertile lemma; gaping. Lower glume lanceolate, or ovate; 1.5–2 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate, or ovate; 1.5–2 mm long; membranous; 1-keeled; 1 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins absent. Upper glume apex acute.

FLORETS Basal sterile florets male, or barren; with palea; persisting on inflorescence. Lemma of lower sterile floret similar to upper glume; lanceolate; 1–1.25 mm long; chartaceous; 1-keeled; 3 -veined; scaberulous; dentate; 2 -fid; mucronate. Palea of lower sterile floret 0.75 mm long. Fertile lemma lanceolate; 1.8 mm long; coriaceous; without keel. Lemma margins involute; interlocking with palea keels. Lemma apex lobed; 2 -fid; incised 0.5 of lemma length; setaceously attenuate; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 2.5 mm long overall; with twisted column. Column of lemma awn 1 mm long. Palea with auriculate flaps; 1 mm long; coriaceous; 2 -veined.
