Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Perennial with a more or less erect, few-branched axis to c. 1 m high, normally leafless in the upper c. two-thirds. Petioles of basal leaves usually longer than lamina; lamina oblong to narrowly ovate, 5–20 cm long, 1–6 cm wide, sometimes constricted above the broadly cuneate to cordate base; margins weakly to strongly crisped. Inflorescence to c. 70 cm high, 20 cm wide; flower 'whorls' mostly 1–5 cm apart, 5–8(–16)-flowered, not subtended by a leaf. Fruiting valves c. triangular, 2.5–4 mm long, 1.5–3 mm wide (excluding teeth), prominently reticulate, with 3–5 strongly hooked teeth along each side, apex of each valve also hooked; callosities normally absent (but hybrids often with callosities); fruiting pedicel subequal to valves, jointed near base. Nut 1.5–2.5 mm long. Flowers mainly Sep.–Jan.

New Zealand, Timor, New Guinea, Java, a rare weed in Europe, the seeds probably accidentally introduced with wool from Australia. Except for dry and sandy areas of the further north-west, widespread and common along watercourses, in depressions and other water-retentive soils almost throughout the State.

Hybrids with Rumex tenax usually have a more divaricately branched inflorescence, and fruiting valves with prominent callosities as in that species.
