Rumex tenax Rech.f. APNI* 
Description: Perennial 15–50 cm high, stems erect, flexuous.
Basal leaves long-petiolate; lamina linear, 9–16 cm long, c. 5 mm wide, apex very acute, base slightly widened to broad-cuneate, lower surface rather striate, not papillose; stem leaves to 10 cm long, 3–4 mm wide, shortly petiolate.
Flower whorls distant, with subtending leaf many times longer than whorl, flowers numerous per whorl.
Fruiting valves 2.5–3.5 mm long, c. 1.5 mm wide, with 1 (or 2) teeth on each side. Fruiting pedicels 1–11/2 times as long as valves, articulate near base.
Distribution and occurrence: Widespread in NSW (but not known from NC, SC and CT). From near Taroom in central Qld south to Murray Bridge, SA, mainly inland (Rechinger 1984: fig. 11B); known from one locality each in WA and NT, and presumably introduced there. In seasonally wet, low-lying areas in grasslands, growing in water to 10 cm deep.
