Low to short erect plant which is golden yellow in fruit.

Rumex palustris has been recorded in VC55

Tubercles yellow, valves with fine slender teeth

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 is needed.

Only found in wetland habitats such as pond and reservoir margins, and with a preference for bare, muddy ground e.g in the draw-down zone of reservoirs.

Flowering June to early October.

Annual.

Widespread though rather local in England, fewer records from elsewhere in Britain.

Near scarce in Leicestershire and Rutland. In the Flora of Leicestershire (Primavesi and Evans 1988) it was found in 18 of the 617 tetrads.

In the VC55 Checklist (Jeeves, 2011) it is listed as Native; scarce, but apparently spreading. 

It was on the 2011 VC55 Rare Plant Register (Jeeves, 2011) but just misses the criteria for the current RPR (Hall and Woodward, 2022)
