Rumex crystallinus

Annual to c. 40 cm high, often drying red-brown, with several to many, usually simple branches from base. Basal leaves with petioles shorter to longer than lamina; lamina oblong, 2–8 cm long, 2–12 mm wide, bases truncate, usually slightly dilated; margins strongly crisped, sometimes recurved; upper leaves reduced but petiolate. Inflorescence often occupying most of plant; flower 'whorls' many-flowered separated by less than 1 cm, contiguous above, each subtended by a leaf. Fruiting valves narrowly triangular or trullate, 1.5–2 mm long, 0.5–1 mm wide (excluding teeth), 1–2-toothed near base (rarely the teeth absent); callosities present on each valve, c. one-third as long as valve; fruiting pedicel subequal to or slightly longer than valves, jointed near base. Nut c. 1 mm long. Flowers Oct.–Mar. (dependent on seasonal rains or river–levels).
