    Glume
    Glumes similar; shorter than spikelet. Lower glume lanceolate; 4-5.5 mm long; 0.75 length of upper glume; coriaceous; much thinner on margins; without keels; 3-5 -veined. Lower glume surface puberulous; hairy on veins. Lower glume apex acute, or acuminate. Upper glume lanceolate; 5.5-8 mm long; 0.66-0.9 length of adjacent fertile lemma; coriaceous; with scarious margins; without keels; 3-5 -veined. Upper glume surface puberulous; hairy on veins. Upper glume apex acute, or acuminate.
    Florets
    Fertile lemma lanceolate; 8-9 mm long; coriaceous; mid-green, or mid-green and purple; suffused with last colour; keeled; keeled above; 5 -veined. Lemma surface puberulous.

Palea surface puberulous; hairy on back. Palea apex emarginate, or truncate. Apical sterile florets resembling fertile though underdeveloped.
