INFLORESCENCE Inflorescence a panicle.

Panicle open; linear; 8–15 cm long. Primary panicle branches indistinct the panicle almost racemose.

Spikelets solitary. Fertile spikelets pedicelled.

Upper glume lanceolate; 10 mm long; membranous; without keels. Upper glume apex acute; awned; 1 -awned. Upper glume awn 3 mm long.

FLORETS Fertile lemma lanceolate; 12 mm long; chartaceous; without keel. Lemma apex acute; awned; 1 -awned. Principal lemma awn 3 mm long overall. Palea 1 length of lemma. Apical sterile florets resembling fertile though underdeveloped.
