HABIT Annual; caespitose; clumped moderately, or densely. Culms erect; 25–50 cm long; 2 -noded. Culm-nodes glabrous. Lateral branches lacking, or sparse. Leaf-sheaths loose; smooth; glabrous on surface. Leaf-sheath oral hairs lacking. Ligule a fringe of hairs; 0.25 mm long. Leaf-blades 2–4 mm wide. Leaf-blade surface smooth; glabrous.
INFLORESCENCE Inflorescence a panicle.
Panicle open, or contracted; lanceolate to ovate; 4–30 cm long; 0.5–12 cm wide; contracted about secondary branches. Panicle axis scabrous.
Spikelets solitary. Fertile spikelets pedicelled. Pedicels 0.5–1 mm long; scabrous.
FERTILE SPIKELETS Spikelets comprising 3–10 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 1.5–3.5 mm long; 0.5–1 mm wide; breaking up at maturity; disarticulating below each fertile floret.
GLUMES Glumes deciduous; similar; shorter than spikelet. Lower glume lanceolate; 0.5–1 mm long; 1 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume primary vein scaberulous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 0.5–1 mm long; 0.5–1 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scaberulous. Upper glume lateral veins absent. Upper glume apex acute.
FLORETS Fertile lemma ovate; 1 mm long; membranous; keeled; 3 -veined. Lemma lateral veins close to margins. Lemma apex acute. Palea 1 length of lemma. Palea keels scabrous. Apical sterile florets resembling fertile though underdeveloped.
FLOWER Lodicules 2; cuneate; fleshy. Anthers 0.1–0.2 mm long.
FRUIT Caryopsis with adherent pericarp.
DISTRIBUTION Australasia: Australia.
