Morphology Leaves
Leaves absent. Leaf sheaths pink (basal ones) to grey, usually much wider than the stem, ending in a broad lobe
Morphology Reproductive morphology Inflorescences
Inflorescence a dense head of up to 25 spikelets, lateral because overtopped by the erect main inflorescence bract, this 6–40 × 0.1–0.8 cm, structure like stem and visibly chambered by transverse septa.
Morphology Reproductive morphology Inflorescences Spikelets
Spikelets red-brown and green, 6–18 × 4–10 mm.
Morphology Reproductive morphology Inflorescences Bracts Glume
Glumes brown to reddish brown with green midrib, triangular, 4–6.5 mm long, slightly concave, acute to mucronate

Morphology Reproductive morphology Fruits
Nutlet white turning to almost black, slightly obovoid, 1.8–2 × 1.5–1.7 mm, 3-angled, smooth; apex with or without minute flat rim.
Morphology Reproductive morphology Flowers
Note that flowers may also be present at the base of the plant, in the axils of the sheaths.
Morphology Reproductive morphology Flowers Gynoecium Style
Styles to 5 cm long, nutlet brown or black, ± globose, 3–5 mm across, remaining in sheath base. Style 3-branched
Ecology
Pool edges, waterholes, sides of watercourses and the sea, on mud or in up to 30 cm deep water (within the grassland/wooded grassland/Acacia bushland zone); 0–1200 m
Note
