Leaf-blades lanceolate to oblong; (18–)25–40 cm long; (40–)60–100 mm wide. Leaf-blade venation with distinct cross veins. Leaf-blade apex acute.

INFLORESCENCE Synflorescence compound; linear (spiciform); 7–14 cm long. Inflorescence comprising only a few spikelets; comprising 1 fertile spikelets; terminal and axillary; subtended by a spatheole; enclosed. Spatheole lanceolate (enclosing a florescence of 1–5 spikelets, its branches each subtended by 2 bracts); 4.5–9 cm long; herbaceous (with cross-veins).

Spikelets solitary. Fertile spikelets pedicelled. Pedicels 7–15 mm long; tip pyriform.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets oblong; curved; laterally compressed; 10–15 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 3–4 mm long; truncate.

GLUMES Glumes one the lower absent or obscure; deciduous; shorter than spikelet; thinner than fertile lemma. Upper glume lanceolate; 10–15 mm long; 0.5 length of adjacent fertile lemma; herbaceous; without keels; 10–17 -veined. Upper glume lateral veins with cross-veins. Upper glume apex obtuse.

FLORETS Fertile lemma ovate; 9–13 mm long; coriaceous; much thinner above; pallid; without keel; 9–15 -veined. Lemma surface pubescent. Lemma margins convolute. Lemma apex caudate; with a conical beak (herbaceous, deciduous); with this appendage 13–18 mm long. Palea absent or minute.

FLOWER Lodicules represented by a ring of hairs. Anthers 4; 3–5 mm long. Stigmas 1; terminally exserted; papillose.
