How to tell it
An upright branched stem to a metre. Elongated leaves, the lower ones fiddle-shaped, narrowed in the middle. The fruits are the mark: gathered in small rings well separated along the branches, and nearly every branch has a leaf at its base. Each fruit has three elongated tubercles.
What it is confused with
Curled dock
Rumex crispus
The leaves are confused. Curled dock has strongly wavy crimped margins and fruits in dense continuous rings along the top; clustered dock has flat fiddle-shaped leaves and fruits in small well-separated rings, with a leaf at each branch base. Both were eaten cooked.
