Rhachis narrowly winged; angular; scaberulous on margins. Spikelets solitary, or in pairs. Fertile spikelets pedicelled. Pedicels oblong; 1-3 mm long; scabrous; bearing a few hairs; hairy at tip; with 1-4 mm long hairs.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; acuminate; 5-7 mm long; falling entire. Spikelet callus globular; incorporating lowest rhachilla internode with adnate lower glume; glabrous.
    Fertile

    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret similar to upper glume; elliptic; 0.9 length of spikelet; 5 -veined; pilose; hairy below; acuminate. Fertile lemma elliptic; 3 mm long; indurate; without keel. Lemma margins involute. Lemma apex acute; pubescent; mucronate. Principal lemma awn 1.5 mm long overall. Palea involute; indurate.
