Leaf-sheaths loose; mostly shorter than adjacent culm internode; striately veined; smooth; glabrous on surface; outer margin hairy. Leaf-sheath oral hairs ciliate. Ligule a fringe of hairs; 1-2 mm long. Leaf-blades linear, or lanceolate; 6-10 cm long; 3-6 mm wide. Leaf-blade venation with 6-8 secondary veins. Leaf-blade surface scaberulous; rough adaxially; pubescent; sparsely hairy; hairy abaxially. Leaf-blade margins cartilaginous; smooth, or scaberulous. Leaf-blade apex acute.
    Inflorescences
    Inflorescence a panicle. Panicle open; ovate; loose; 6-10 cm long; contracted about primary branches. Primary panicle branches spreading; 1 -nate; 2-3.5 cm long. Panicle axis smooth. Panicle branches bearing approximate spikelets. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; unequal; 0.5-2 mm long; tip widened.
    Spikelets
    Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 1.2-1.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.
    Fertile
    Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 1.2-1.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes definite.
    Glume
    Glumes deciduous; similar; shorter than spikelet, or reaching apex of florets; thinner than fertile lemma. Lower glume elliptic; 1.1-1.5 mm long; 1 length of upper glume; 0.95-1 length of spikelet; membranous; without keels; 7 -veined. Lower glume surface puberulous; hairy at apex. Lower glume apex obtuse. Upper glume elliptic; 1.1-1.5 mm long; 0.95-1 length of spikelet; membranous; without keels; 5-7 -veined. Upper glume surface puberulous; hairy at apex. Upper glume apex obtuse.
    Florets
    Fertile florets female; with the lowest dissimilar. Lowest fertile lemma bisexual, or female; elliptic; 1.2-1.5 mm long; thinner than adjacent lemma; glabrous. Fertile lemma elliptic; 1 mm long; coriaceous; without keel; 0 -veined. Lemma surface puberulous. Lemma margins involute. Lemma apex obtuse. Palea 1 length of lemma; coriaceous.
