Primary panicle branches spreading; simple. Panicle axis puberulous; with hooked hairs; bearing deciduous branches. Panicle branches stiff; pubescent; with hooked hairs. Sexes mixed. Spikelets appressed; in pairs. Fertile spikelets sessile; 1 in the cluster. Male spikelets pedicelled; 1 in a cluster. Pedicels filiform.
    Spikelets

    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear; curved (sigmoid); subterete; 9-11 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 5.5-6 mm long; 0.8-0.9 length of upper glume; scarious; dark brown; without keels; 6-9 -veined. Lower glume apex acute. Upper glume lanceolate; 6-6.5 mm long; 0.66 length of adjacent fertile lemma; scarious; dark brown; without keels; 5 -veined. Upper glume apex acute.
    Florets

Lemma margins involute; interlocking with palea keels. Lemma apex acute; with a conical beak; with this appendage 0.5-1 mm long. Palea linear; 1 length of lemma; 2 -veined.
    Flowers

    Fruits
    Caryopsis with adherent pericarp; oblong; sulcate on hilar side.
    Male
