- Synflorescence compound; paniculate; 30-60 cm long; dense. Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; embraced at base by subtending leaf. Spatheole lanceolate; 2.5-3.5 cm long; scarious; green; without tubercles; glabrous. Racemes 1; single; oblong; bearing few fertile spikelets; bearing 2-4 fertile spikelets on each. Rhachis fragile at the nodes. Rhachis internodes linear. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels oblong; 0.5 mm long.

- Basal sterile spikelets well-developed; 4 in number; forming an involucre about the fertile; subsessile; lanceolate; 5-13 mm long; larger than fertile. Basal sterile spikelet glumes smooth, or tuberculate; pubescent; smooth on margins, or ciliate on margins (rufously); lower glume muticous. Companion sterile spikelets well-developed; male; lanceolate; 10-12 mm long; longer than fertile; separately deciduous. Companion sterile spikelet callus linear. Companion sterile spikelet glumes smooth; glabrous. Companion sterile spikelet lemmas 2; enclosed by glumes.
- Morphology Reproductive morphology Inflorescences Spikelets
- Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; compressed slightly; 7-8 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus cuneate; bearded; base acute; attached obliquely. Spikelet callus hairs red.

- Morphology Reproductive morphology Inflorescences Bracts Glume
- Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; coriaceous; without keels. Lower glume surface pubescent. Lower glume hairs red. Lower glume apex obtuse. Upper glume oblong.
- Morphology Reproductive morphology Flowers Florets
- Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; hyaline. Fertile lemma lanceolate; hyaline; without keel; 1 -veined. Lemma apex entire; muticous, or awned; 1 -awned. Principal lemma awn apical; geniculate; 0-10 mm long overall; with twisted column. Column of lemma awn puberulous. Palea absent or minute.
