Curled Dock - Rumex crispus
Medium to tall plant. Leaves narrow-lanceolate with very wavy margins, short stalked. Flowerheads dense, in branched spikes, branches rather upright. Fruit valves heart shaped, 1 -3 swollen tubercles.
Tubercles oblong, one (or rarely all 3) well-developed, valves triangular, rounded, no lateral teeth. Leaves with wavy margins.
The fruits have a central part, triangular in cross-section, with three membraneous valves surrounding a small, hard 'tubercle'. The shape and arrangement of valves and tubercles is diagnostic, and close-up photos of fruits and leaves/general habit are needed.
Disturbed and cultivated land, waste places, hedge banks.
June to October.
Quite common in much of Britain, but less so in the north.
