    Inflorescences
    Inflorescence a panicle with branches tipped by a raceme. Panicle open. Primary panicle branches whorled at most nodes. Racemes bearing few fertile spikelets; 3-7 fertile spikelets on each. Rhachis fragile at the nodes; angular (1), or subterete (1). Rhachis internodes filiform. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels filiform.
    Spikelets
    Companion sterile spikelets well-developed; separately deciduous. Companion sterile spikelet glumes muticous. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 3.5-4.662-6 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pubescent; base obtuse; attached transversely.
    Sterile
    Companion sterile spikelets well-developed; separately deciduous. Companion sterile spikelet glumes muticous.

Lemma margins ciliolate. Lemma apex entire (1), or dentate; 2 -fid; muticous (1), or awned (1); 1 -awned (1/1). Principal lemma awn from a sinus (1/1); flexuous (1/1).
