The wood dock is a native perennial and is so-called because its characteristic habitat is woodland, especially on clay. It is similar in general appearance to the clustered dock (Rumex conglomeratus) but unlike that species its fruit has only a single swollen wart (three in R. conglomeratus). Generally speaking, clustered dock grows in much wetter situations.

[R. sanguineus var. sanguineus is a much rarer plant, with bright red leaf-veins, giving it the common name of 'bloody dock'. It has occurred occasionally as a casual, but there are no modern reports from Northern Ireland. It is not native.]

All names: Rumex sanguineus var. viridis (Sibth.) Koch
