INFLORESCENCE Inflorescence composed of racemes. Peduncle pubescent above.

Racemes 8–10; digitate; 5–7.5 cm long. Rhachis tough; angular; glabrous on surface. Rhachis internodes filiform; 3–4 mm long.

Spikelets in pairs. Fertile spikelets pedicelled; 2 in the cluster. Pedicels filiform; unequal; 1–1.5 mm long, or 2.5–3 mm long; glabrous.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; 5–5.5 mm long; falling entire. Spikelet callus bearded; base truncate. Spikelet callus hairs white; 0.66 length of spikelet.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; chartaceous; much thinner above; without keels; 4 -veined. Lower glume lateral veins ribbed. Lower glume surface flat; villous. Lower glume hairs 3–3.5 mm long. Lower glume apex emarginate, or truncate. Upper glume lanceolate; chartaceous; 1-keeled; keeled above; 5 -veined. Upper glume primary vein ciliate. Upper glume apex obtuse.

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; ciliolate on margins; fringed above; erose; acute. Fertile lemma lanceolate; 2.5 mm long; hyaline; without keel; 1 -veined. Lemma margins ciliate; hairy above. Lemma apex entire, or dentate; 2 -fid; awned; 1 -awned. Principal lemma awn apical, or from a sinus; geniculate; 6–8 mm long overall; with a straight or slightly twisted column. Palea 3.5 mm long.
