| Rumex sanguineus | |
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 to the base of the plant only. They are deciduous to partially persistent at maturity. The blade of the leaf is lance shaped with a more or less pointed base at the end and on average measure 10–30 × 2.5–6 cm. Rumex sanguineus flowers in the summer in moist and riparian habitat. Flower is terminal and occupies the top 2/3 of the stem. Inflorescence is lax, interrupted, broadly paniculate. [3] The pedicel, stalk bearing the inflorescence, is proximal 1/3 and rarely in the middle of the filiform. In general, it is larger than the inner tepals with distinctly swollen articulation. When flowering there are normally ten to twenty flowers in each well-spaced whorl. Achenes are dark reddish brown to almost black.
It is differentiated from the very similar Rumex conglomeratus by a more slender and erect habitus. [4]
Rumex sanguineus is commonly found in most of Europe south of about 60 degrees north, though not in Russia and rarely in the Mediterranean. It inhabits damp, shady places, especially in woodland. [1] [4] It is a crop-weed that can be found on less arable fields on the outskirt 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 poisonous and should therefore 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 commercially [7] [8] [9] available. It contains considerable amounts of vitamin C and carotene. [10] Normally the (preferably young) leaves are eaten, for example in salads. However, related species such as garden sorrel and French sorrel are generally preferred when it comes to vegetable use. [2] In comparison, the wood dock is said to have less taste and more ornamental values. [11] Since mainly the leaves are valued, the less conspicuous inflorescences are often removed early on to promote stronger and bushier leaf growth and also to prevent (possibly heavy) uncontrolled spreading.

Sorrel, also called common sorrel or garden sorrel, is a perennial herbaceous plant in the family Polygonaceae. Other names for sorrel include spinach dock and narrow-leaved dock.
The docks and sorrels, genus Rumex, are a genus of about 200 species of annual, biennial, and perennial herbs in the buckwheat family, Polygonaceae. Members of this genus are very common perennial herbs with a native almost worldwide distribution, and introduced species growing in the few places where the genus is not native.

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 longifolius, commonly known as the dooryard dock or northern dock, is a perennial species of plant in the genus Rumex.
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 sagittatus, synonym Acetosa sagittata, commonly known as turkey rhubarb or rambling dock or potato vine, is a herbaceous perennial plant native to southern Africa, which has become a weed in Australia and New Zealand.
Rumex brownii, the hooked dock, Browne's dock or swamp dock, is a leafy perennial herb native to Australia, and is widespread and grows in disturbed sites. It is an introduced weed in the Pacific Islands, England, Japan, and New Zealand.
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 grows in disturbed habitat, often in moist areas, such as lakeshores and the edges of cultivated fields. 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. Each flower has usually six tepals, the 3 inner of which are edged with spinelike teeth and have tubercles at their centers.
Rumex paucifolius is a species of flowering plant in the knotweed family known by the common name alpine sheep sorrel.

It is native to Eurasia and North Africa and it can be found elsewhere, including parts of North America, as an introduced species and a roadside weed. Europe. It is quite variable in appearance, and some authorities divide it into several subspecies that are more or less distinguishable. In general, it is a perennial herb producing a slender, erect stem from a thick taproot, approaching 70 centimeters in maximum height. The top of the plant may bend, especially as the fruit develops. The leaves are up to 10 or 15 centimeters long and variable in shape, though often oblong with a narrow middle in the rough shape of a fiddle.
