    [GB]
    Habit
    Perennial. Culms decumbent; weak; 8-50 cm long; rooting from lower nodes. Culm-internodes distally glabrous. Lateral branches sparse. Leaf-sheaths glabrous on surface to pubescent; outer margin hairy. Ligule a fringe of hairs; 1-2 mm long. Leaf-blades lanceolate, or oblong; 1.5-7 cm long; 3-8 mm wide. Leaf-blade surface scabrous; rough on both sides; glabrous, or pilose; sparsely hairy.
    Inflorescences
    Inflorescence a panicle. Panicle open; elliptic; 3-10 cm long; contracted about primary branches. Primary panicle branches ascending. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets orbicular; tilted on the pedicel; dorsally compressed; 1.5-1.7 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes flattened.
    Fertile
    Spikelets comprising 2 fertile florets; without rhachilla extension. Spikelets orbicular; tilted on the pedicel; dorsally compressed; 1.5-1.7 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes flattened.
    Glume
    Glumes deciduous; similar; reaching apex of florets; thinner than fertile lemma. Lower glume obovate; 1.5-1.7 mm long; 1 length of upper glume; 1 length of spikelet; membranous; without keels. Lower glume surface glabrous, or hispidulous. Lower glume apex obtuse. Upper glume obovate; 1.5-1.7 mm long; 1 length of adjacent fertile lemma; membranous; without keels. Upper glume surface glabrous, or hispidulous. Upper glume apex obtuse.
    Florets
    Fertile florets with the lowest dissimilar. Lowest fertile lemma 1.05 length of adjacent lemma; thinner than adjacent lemma (slightly). Fertile lemma elliptic, or orbicular; 1.5-1.7 mm long; coriaceous; shiny; without keel. Lemma surface glabrous. Lemma margins involute. Lemma apex obtuse. Palea coriaceous; 2 -veined.
