INFLORESCENCE Inflorescence a panicle with branches tipped by a raceme. Peduncle hirsute above.

Panicle open; lanceolate; 10–20 cm long; 2–3 cm wide.

Racemes 1.5–7.5 cm long. Rhachis fragile at the nodes; subterete; villous on surface. Rhachis internodes filiform.

Spikelets in pairs. Fertile spikelets sessile and pedicelled; 2 in the cluster; subequal. Pedicels filiform; villous.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 4.5–8 mm long; falling entire; deciduous from the base, or with accessory branch structures. Spikelet callus bearded; base truncate. Spikelet callus hairs white; 4.5–5.5 mm long; 0.75–1 length of spikelet.

GLUMES Glumes similar; firmer than fertile lemma. Lower glume elliptic, or oblong; 4–6 mm long; 0.75–0.9 length of spikelet; coriaceous; much thinner above; 2-keeled. Lower glume surface flat. Lower glume margins ciliate. Lower glume apex acute, or acuminate. Upper glume lanceolate; 5–8 mm long; 1 length of spikelet; coriaceous; much thinner above; without keels. Upper glume margins ciliate. Upper glume apex setaceously attenuate, or caudate.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret elliptic; hyaline; 0–1 -veined; without midvein, or with evident midvein; without lateral veins; ciliolate on margins; acute; muticous, or mucronate. Fertile lemma linear, or lanceolate; hyaline. Lemma margins ciliate. Palea absent or minute.
