    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; oblong; 1-1.3 cm long; bearing few fertile spikelets; bearing 1 fertile spikelets on each. Rhachis obsolete (raceme capitate). Spikelets in threes. Fertile spikelets pedicelled; 1 in the cluster. Companion sterile spikelets sessile; 2 in the cluster. Pedicels 3-3.2 mm long.
    Spikelets
    Companion sterile spikelets well-developed; male; oblong; dorsally compressed; 10-11 mm long; longer than fertile; persistent. Companion sterile spikelet glumes coriaceous; 7-9 -veined (lower); dentate (lateral teeth 1-3.5mm long); truncate; muticous. Companion sterile spikelet lemmas 1; enclosed by glumes; 8-10 mm long; entire; muticous. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 6-7 mm long; falling entire. Spikelet callus linear; 2 mm long; base pungent; attached obliquely.
    Sterile

Companion sterile spikelet lemmas 1; enclosed by glumes; 8-10 mm long; entire; muticous.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 6-7 mm long; falling entire. Spikelet callus linear; 2 mm long; base pungent; attached obliquely.
    Glume
    Glumes similar; reaching apex of florets; firmer than fertile lemma. Lower glume lanceolate, or ovate; 6-7 mm long; 1.2 length of upper glume; 1 length of spikelet; chartaceous; without keels; 3 -veined. Lower glume apex truncate, or obtuse. Upper glume lanceolate, or ovate; 5-6.5 mm long; chartaceous; without keels; 3 -veined. Upper glume apex truncate, or obtuse.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret oblong; 3 mm long; hyaline. Fertile lemma linear; hyaline; without keel. Lemma apex entire; awned; 1 -awned. Principal lemma awn geniculate; 65 mm long overall; with twisted column. Column of lemma awn pubescent. Palea absent or minute.
