Rumex sanguineus, commonly known as wood dock, [1] bloody dock or red-veined dock, [2] is a perennial flowering plant species in the family Polygonaceae. Rumex sanguineus is a dicot and can be observed in Europe with at least two varieties. [3]
The leaves are situated at the base of the plant only. They are deciduous to partially persistent at maturity. The leaf blade is lanceolate with a more or less pointed tip averages 10–30 × 2.5–6 cm. Rumex sanguineus flowers in the summer in wet riparian habitat. The flower is terminal and occupies the upper 2/3 of the stem. The inflorescence is lax, interrupted, and broadly paniculate. [3] The pedicel, the stem bearing the inflorescence, is proximal 1/3 and rarely in the middle of the filiform. It is generally larger than the inner tepals with distinctly swollen articulation. There are normally ten to twenty flowers in each well-spaced whorl. The achenes are dark reddish brown to almost black.
It is distinguished from the very similar Rumex conglomeratus by a more slender and erect habit. [4]
Rumex sanguineus is common in most of Europe south of about 60 degrees north, but not in Russia and rarely in the Mediterranean. It inhabits damp, shady places, especially in woodland. [1] [4] It is an agricultural weed that can be found in the vegetation surrounding arable fields. [5] [ citation needed ]Rumex sanguineus is not native to North America with most reports of Rumex sanguineus being confused with R. conglomeratus or immature R. obtusifolius.
The wood dock is edible. However, as it contains antinutritive and harmful oxalic acid and its salts (oxalates), it is slightly toxic and should not be eaten in large quantities. [6] (The contents are lower than in the related and better-known sorrel.) It is both used as a wild vegetable and cultivated, with plants and seeds being sold commercially [7] [8] [9] available. It contains considerable amounts of vitamin C and carotene. [10] The (preferably young) leaves are eaten, for example in salads. However, related species such as garden sorrel and French sorrel are generally preferred for use as a vegetable. [2] Wood dock is said to be less flavoursome and more ornamental. [11] Since mainly the leaves are valued, the less conspicuous inflorescences are often removed early to stimulate stronger and bushier leaf growth and to prevent (possibly heavy) uncontrolled spreading.

Rumex obtusifolius, commonly known as bitter dock, broad-leaved dock, bluntleaf dock, dock leaf, dockens or butter dock, is a perennial plant in the family Polygonaceae. It is native to Europe, but is found on all temperate continents. It is a highly invasive species in some zones, resulting from its abundant seed dispersal, adaptability to reproduce, aggressive roots, ability to tolerate extreme climates, and hardiness.
Rumex acetosella, commonly known as red sorrel, sheep's sorrel, field sorrel and sour weed, is a species of flowering plant in the buckwheat family Polygonaceae. Native to Eurasia and the British Isles, the plant and its subspecies are common perennial weeds. It has green arrowhead-shaped leaves and red-tinted deeply ridged stems, and it sprouts from an aggressive and spreading rhizome. The flowers emerge from a tall, upright stem. Female flowers are maroon in color.
Rumex hymenosepalus, commonly known as canaigre, canaigre dock, ganagra, wild rhubarb, Arizona dock, and tanner's dock, is a perennial flowering plant which is native to the North American deserts in the southwestern United States and northern Mexico. It is a common food plant of the ruddy copper larvae.
Rumex maritimus, commonly called golden dock, bristle dock, or seashore dock, is an annual plant species of the genus Rumex. Rumex maritimus grows in Argentina, Burma, Canada, China, and the United States. It is native to Canada and most of the 48 states. The life span of Rumex maritimus is rarely biennial in moist environments. This herb belongs to the family Polygonaceae.

Rumex dentatus is a species of flowering plant in the knotweed family known by the common names toothed dock and Aegean dock. It is native to parts of Eurasia and North Africa, and it is widely known elsewhere as an introduced species.

It is an annual or biennial herb producing a slender, erect stem up to 70 or 80 centimeters in maximum height. The leaves are lance-shaped to oval with slightly wavy edges, growing to a maximum length around 12 centimeters. The inflorescence is an interrupted series of clusters of flowers, with 10 to 20 flowers per cluster and each flower hanging on a pedicel.
