HABIT Perennial. Rhizomes short. Culms erect; 50–70 cm long. Culm-internodes smooth, or scaberulous. Lateral branches lacking. Leaf-sheaths tubular for much of their length; with 1 of their length closed; retrorsely scabrous. Ligule an eciliate membrane; 0.5–5 mm long; lacerate. Leaf-blades flat, or convolute; 1.5–15 cm long; 1.5–3 mm wide; stiff. Leaf-blade surface scabrous; rough on both sides. Leaf-blade margins scabrous.

INFLORESCENCE Inflorescence a panicle.

Panicle open; pyramidal; 5–25 cm long. Panicle axis scaberulous. Panicle branches scaberulous.

Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform; curved; ciliate; hairy above.

FERTILE SPIKELETS Spikelets comprising 1 fertile florets; with diminished florets at the apex. Spikelets obovate; dorsally compressed; 7–11 mm long; falling entire. Floret callus glabrous.

GLUMES Glumes dissimilar; with lower wider than upper; exceeding apex of florets; thinner than fertile lemma. Lower glume obovate; 7–11 mm long; 1.3–1.4 length of upper glume; membranous; much thinner above; much thinner on margins; without keels; 7–11 -veined. Lower glume primary vein falling short of apex. Lower glume apex entire; acute. Upper glume lanceolate; 5–8 mm long; 1 length of adjacent fertile lemma; membranous; much thinner above; with hyaline margins; without keels; 5–7 -veined. Upper glume surface asperulous. Upper glume apex obtuse.

FLORETS Fertile lemma lanceolate; 5–7 mm long; 2–2.5 mm wide; chartaceous; much thinner above; much thinner on margins; without keel. Lemma margins ciliate; hairy in the middle. Lemma apex entire, or dentate; 2 -fid; acute. Palea 3.5–6 mm long; 2 -veined. Palea keels ciliolate. Palea surface asperulous. Palea apex acute. Apical sterile florets barren; in a clump; oblong; 2–2.5 mm long. Apical sterile lemmas truncate.

FLOWER Lodicules 2; united; oblong; 0.2 mm long; fleshy; glabrous; truncate. Anthers 3; 1.5–2.5 mm long.

FRUIT Caryopsis with adherent pericarp; ellipsoid; 2.8–3.5 mm long; dark brown. Embryo 0.25 length of caryopsis. Hilum linear.

DISTRIBUTION South America: southern South America.
