    Inflorescences
    Inflorescence composed of racemes. Racemes 5-8; digitate; 5-7 cm long. Rhachis fragile at the nodes; flattened; ciliate on margins. Rhachis internodes linear; 2 mm long. Rhachis internode tip transverse. Raceme-bases filiform; simple, or dichotomously branched; 13-20 mm long; pilose; hairy at base. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels linear; flattened; 2 mm long; without a translucent median line; ciliate.
    Spikelets
    Companion sterile spikelets well-developed; containing empty lemmas; lanceolate; 3.5-4 mm long; longer than fertile. Companion sterile spikelet glumes 9 -veined. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 3-3.5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus bearded; base obtuse; attached transversely.
    Sterile
    Companion sterile spikelets well-developed; containing empty lemmas; lanceolate; 3.5-4 mm long; longer than fertile. Companion sterile spikelet glumes 9 -veined.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 3-3.5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus bearded; base obtuse; attached transversely.
    Glume
    Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume elliptic; 1 length of spikelet; chartaceous; without keels; keel-less except near apex; 7-9 -veined. Lower glume surface flat. Lower glume margins ciliate. Upper glume lanceolate; 1 length of spikelet; 1-keeled; 3 -veined. Upper glume apex acuminate; mucronate.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; hyaline; 0 -veined; without midvein; without lateral veins; acute. Fertile lemma linear; 2.5 mm long; hyaline; without keel. Lemma apex entire; awned; 1 -awned. Principal lemma awn apical; geniculate; 15-20 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.
