INFLORESCENCE Inflorescence composed of racemes. Peduncle pilose above.

Racemes 5–8; digitate; 5–9 cm long. Rhachis fragile at the nodes; ciliate on margins. Rhachis internodes linear; 3.5–5 mm long. Rhachis internode tip transverse.

Spikelets in pairs. Fertile spikelets sessile and pedicelled; 2 in the cluster. Pedicels linear; angular; 3–4 mm long; ciliate.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 4.5 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus bearded; base obtuse; attached transversely.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume elliptic; 1 length of spikelet; chartaceous; 2-keeled; keeled above; 2 -veined. Lower glume surface flat, or concave; pilose; hairy below. Lower glume hairs yellow. Lower glume apex acute. Upper glume oblong; 1 length of spikelet; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume awned; 1 -awned. Upper glume awn 12 mm long.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 4 mm long; hyaline; 0 -veined; without midvein; without lateral veins; ciliate on margins; obtuse. Fertile lemma oblong; 4 mm long; hyaline; without keel; 1 -veined. Lemma apex lobed; 2 -fid; with lobes 2 mm long; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 21 mm long overall; with twisted column. Column of lemma awn 4–5 mm long; glabrous. Palea 2 mm long.
