INFLORESCENCE Synflorescence compound; linear; 10–40 cm long. Inflorescence comprising only a few spikelets; comprising 1 fertile spikelets; terminal and axillary; subtended by a spatheole; enclosed. Spatheole linear; 2–3 cm long; scarious.

Spikelets in threes. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 2 in the cluster. Pedicels filiform; 2.5 mm long; ciliate; with red hairs.

STERILE SPIKELETS Companion sterile spikelets represented by barren pedicels.

FERTILE SPIKELETS Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets linear; subterete; 10–11 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus linear; 2 mm long; pubescent; base pungent; attached obliquely. Spikelet callus hairs red.

GLUMES Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 0.9 length of spikelet; coriaceous; dark brown; without keels; 6–7 -veined. Lower glume lateral veins obscure. Lower glume surface puberulous; hairy above. Lower glume apex entire; emarginate. Upper glume oblong; coriaceous; without keels. Upper glume apex entire; acute; muticous, or awned; 1 -awned. Upper glume awn 8–15 mm long.

FLORETS Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; hyaline; 2 -veined; ciliate on margins. Fertile lemma linear; 4 mm long; hyaline; without keel; 1 -veined. Lemma apex lobed; 2 -fid; incised 0.25 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 100–120 mm long overall; with twisted column (black). Column of lemma awn 75–90 mm long; glabrous. Palea absent or minute.
