    [GB]
    Habit
    Perennial; caespitose; clumped densely. Basal innovations intravaginal. Culms erect; 14-75 cm long; 2-4 -noded. Leaf-sheaths glabrous on surface, or pilose. Leaf-sheath oral hairs ciliate; 0.5 mm long. Ligule a fringe of hairs; 0.3-1.5 mm long. Leaf-blades involute; 19-30 cm long; 1-2 mm wide. Leaf-blade surface glabrous, or pilose.
    Inflorescences
    Inflorescence a panicle; comprising 4-24(-100) fertile spikelets. Panicle open; linear; 2.7-18 cm long; 1.5 cm wide; bearing many spikelets, or few spikelets. Primary panicle branches ascending. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 0.5-14 mm long; pubescent.
    Spikelets
    Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 15.5-28.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.5 mm long; glabrous. Floret callus evident; 0.8-1.2 mm long; pubescent, or pilose. Floret callus hairs 0.2-3 mm long.
    Fertile
    Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 15.5-28.5 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.5 mm long; glabrous. Floret callus evident; 0.8-1.2 mm long; pubescent, or pilose. Floret callus hairs 0.2-3 mm long.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 11-24 mm long; 1 length of upper glume; membranous; without keels; 3-5 -veined. Lower glume apex acuminate. Upper glume lanceolate; 10.5-23 mm long; 1-1.1 length of adjacent fertile lemma; membranous; without keels; 5 -veined. Upper glume apex acuminate.
    Florets
    Fertile lemma elliptic; 9-18.5 mm long; chartaceous; without keel. Lemma surface pilose; hairy below. Lemma margins ciliate; hairy below. Lemma hairs 3-4 mm long. Lemma apex lobed; 2 -fid; with lobes 5-12.5 mm long; incised 0.66 of lemma length; awned; 3 -awned. Principal lemma awn from a sinus; geniculate; 10-19.5 mm long overall; with twisted column. Lateral lemma awns arising on apex of lobes; 1-5 mm long; shorter than principal. Palea lanceolate; 4.3-6 mm long; 2 -veined. Palea surface pilose; hairy on margins. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; cuneate; 0.4-0.9 mm long; fleshy; glabrous, or ciliate. Anthers 3; 0.7-4 mm long.
    Fruits
    Caryopsis with adherent pericarp; ellipsoid; 1.7-2.5 mm long; light brown. Embryo 0.5 length of caryopsis. Hilum linear; 0.2-0.3 length of caryopsis.
    Cleistogene
    Cleistogenes present; in lower sheaths; 4.7-7 mm long.
    Distribution
    South America: southern South America.
