Lower glume elliptic; 6-7.5 mm long; 0.8-0.9 length of upper glume; scarious; light brown; without keels; 5-7 -veined. Lower glume apex acute. Upper glume elliptic; 6.5-8 mm long; 0.6 length of adjacent fertile lemma; scarious; light brown; without keels; 5-7 -veined. Upper glume apex acute.
    Florets
    Fertile florets female. Fertile lemma elliptic; subterete; 11.5-13.5 mm long; 2-3 mm wide; coriaceous; light brown; without keel; 7 -veined. Lemma lateral veins obscure. Lemma surface pubescent; hairy all along; with hooked hairs. Lemma margins involute; interlocking with palea keels. Lemma apex acute; with a conical beak. Palea linear; 1 length of lemma; 2 -veined.
    Flowers
    Lodicules absent. Anthers 6; 1.2-2.1 mm long. Stigmas 3.
    Fruits
    Caryopsis with adherent pericarp; linear; isodiametric; stipitate; 9-10 mm long.

Male spikelet lemma 3.2-4.3 mm long; 3 -veined; with cross-veins; muticous. Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets elliptic; straight; subterete; 11.5-13.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
