    Inflorescences
    Inflorescence composed of racemes; terminal and axillary; subtended by a spatheole; exserted. Spatheole linear. Racemes 1; single; smoothly terete; 4-8 cm long. Rhachis fragile at the nodes; angular; 2-2.5 mm wide; glabrous on surface. Rhachis internodes cuneate; 3-4 mm long; with the lower often bearing triads. Rhachis internode tip transverse; crateriform; with simple rim. Spikelets appressed; in pairs, or in threes. Fertile spikelets sessile; 1-2 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels columnar; semiterete; 3.8 mm long; tip cupuliform.
    Sterile
    Companion sterile spikelets rudimentary; comprising 2 subequal glumes without lemmas; lanceolate; 0.6 mm long; shorter than fertile; persistent. Companion sterile spikelet glumes winged on keels.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 3.6 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pubescent; base truncate; with central peg; attached transversely. Companion sterile spikelets rudimentary; comprising 2 subequal glumes without lemmas; lanceolate; 0.6 mm long; shorter than fertile; persistent. Companion sterile spikelet glumes winged on keels.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets ovate; dorsally compressed; 3.6 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pubescent; base truncate; with central peg; attached transversely.
    Glume
    Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume ovate; asymmetrical; 1 length of spikelet; indurate; 2-keeled; winged on keel; winged narrowly; winged near apex; 6 -veined. Lower glume lateral veins ribbed. Lower glume surface tuberculate; pubescent; with tubercle-based hairs. Lower glume apex acute. Upper glume oblong; asymmetrical; chartaceous; 1-keeled; 3 -veined.
    Florets
    Basal sterile florets barren; with palea. Lemma of lower sterile floret oblong; 2.6 mm long; hyaline; 2 -veined. Palea of lower sterile floret 0.8 length of lemma. Fertile lemma elliptic; 2.4 mm long; hyaline; without keel; 3 -veined. Palea 0.66 length of lemma.
