The docks and sorrels, genus Rumex L., are a genus of about 200 species of annual, biennial, and perennial herbs in the buckwheat family Polygonaceae. Members of this family are very common perennial herbs growing mainly in the Northern Hemisphere, but various species have been introduced almost everywhere. Some are nuisance weeds (and are sometimes called dockweed or dock weed), but some are grown for their edible leaves. Rumex species are used as food plants by the larvae of a number of Lepidoptera species.
