The '''docks''' and '''sorrels''', [[genus]] '''''Rumex''''', are a genus of about 200 species of [[Annual plant|annual]], [[Biennial plant|biennial]], and [[perennial plant|perennial]] [[herb]]s 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.<ref name=POWO_328551-2/>

Some are nuisance [[weed]]s (and are sometimes called dockweed or dock weed), but some are grown for their edible [[Leaf|leaves]].<ref>{{cite book |last=Martin |first=Alexander C. |title=Weeds |year=1972 |publisher=Golden Press |location=New York |isbn=0-307-24353-2 |page=[https://archive.org/details/weeds00mart/page/38 38] |url-access=registration |url=https://archive.org/details/weeds00mart/page/38}}</ref> ''Rumex'' species are used as food plants by the [[larva]]e of a number of [[Lepidoptera]] species, and are the only host plants of ''[[Lycaena dispar]]'' and ''[[Lycaena rubidus]].''<ref>{{Cite journal|last1=Warren|first1=Andres|last2=Harrera|first2=Alfonso|date=15 March 2005|title=Butterflies of Oregon Their Taxonomy, Distribution, and Biology|url=https://dspace.library.colostate.edu/bitstream/handle/10217/81121/BSPMGILL_LepidopteraofNorthAmerica6.pdf?sequence=1|journal=Lepidoptera of North America|volume=6}}</ref>

==Description==
They are erect plants, usually with long [[taproot]]s. The fleshy to leathery leaves form a basal rosette at the root. The basal leaves may be different from those near the [[inflorescence]]. They may or may not have [[stipule]]s. Minor leaf veins occur. The leaf blade margins are entire or crenate.

The usually inconspicuous [[flower]]s are carried above the leaves in clusters. The fertile flowers are mostly [[hermaphrodite]]s, or they may be functionally male or female. The flowers and seeds grow on long clusters at the top of a stalk emerging from the basal rosette; in many species, the flowers are green, but in some (such as sheep's sorrel, ''[[Rumex acetosella]]'') the flowers and their stems may be brick-red. Each seed is a three-sided achene, often with a round tubercle on one or all three sides.

==Taxonomy==
The genus was first described by [[Carl Linnaeus]] in 1753. Within the family Polygonaceae, it is placed in the subfamily [[Polygonoideae]]. The genus ''Emex'' was separated from ''Rumex'' by Francisco Campderá in 1819 on the basis that it was polygamous (i.e. had both bisexual and unisexual flowers on the same plant). However, some species of ''Rumex'' subg. ''Acetosa'' also have this characteristic, and most other features that are supposed to distinguish ''Emex'' are found in species of ''Rumex''. Accordingly, in 2015, Schuster et al. demoted ''Emex'' to a subgenus of ''Rumex''.<ref name=SchuReveBaylKron15>{{Citation |mode=cs1|last1=Schuster |first1=Tanja M. |last2=Reveal |first2=James L. |last3=Bayly |first3=Michael J. |last4=Kron |first4=Kathleen A. |date=2015 |title=An updated molecular phylogeny of Polygonoideae (Polygonaceae): Relationships of ''Oxygonum'', ''Pteroxygonum'', and ''Rumex'', and a new circumscription of ''Koenigia'' |journal=Taxon |volume=64 |issue=6 |pages=1188–1208 |doi=10.12705/646.5 |bibcode=2015Taxon..64.1188S |name-list-style=amp}}</ref>

Within the subfamily Polygonoideae, ''Rumex'' is placed in the tribe Rumiceae, along with the two genera ''[[Oxyria]]'' and ''[[Rheum (plant)|Rheum]]''. It is most closely related to ''Rheum'', which includes [[Rhubarb]].<ref name=SchuReveBaylKron15/>

==Uses==

These plants have many uses. Broad-leaved dock (''[[Rumex obtusifolius]]'') used to be called butter dock because its large leaves were used to wrap and conserve [[butter]].

''[[Rumex hymenosepalus]]'' has been cultivated in the Southwestern US as a source of [[tannin]] (roots contain up to 25%), for use in leather tanning, while leaves and stems are used for a [[mordant]]-free mustard-colored [[dye]].

These plants are edible. The leaves of most species contain [[oxalic acid]] and tannin, and many have [[astringent]] and slightly [[purgative]] qualities. Some species with particularly high levels of oxalic acid are called sorrels (including sheep's sorrel ''[[Rumex acetosella]]'', common sorrel ''[[Rumex acetosa]]'', and French sorrel ''[[Rumex scutatus]]''), and some of these are grown as [[leaf vegetable]]s or garden [[herb]]s for their acidic taste.<ref>{{cite web |url=http://www.botanical.com/botanical/mgmh/s/sorcom64.html |title=Sorrel, Garden or Common [''Rumex acetosa''] |website=Botanical.com}}</ref><ref>{{cite journal | journal = Journal of Ethnobiology and Ethnomedicine | year = 2008 | volume = 4 | issue = 1 | doi = 10.1186/1746-4269-4-4 |pmc=2275233 | title = Archival data on wild food plants used in Poland in 1948 | first = Łukasz | last = Łuczaj | page = 4 | pmid = 18218132 | doi-access = free }}</ref>

In the United Kingdom, ''[[Rumex obtusifolius]]'' is often found growing near [[Urtica dioica|stinging nettles]], owing to both species favouring a similar environment, and there is a widely held belief that the underside of the dock leaf, squeezed to extract a little juice, can be rubbed on the skin to counteract the itching caused by brushing against a nettle plant.<ref>{{cite web |work=Ethnomedica |url=http://www.rbgkew.org.uk/ethnomedica/reports/dock.html |title=Recorded uses of' dock (''Rumex'' sp.) |access-date=2008-04-15 |url-status=dead |archive-url=https://web.archive.org/web/20081120040109/http://www.rbgkew.org.uk/ethnomedica/reports/dock.html |archive-date=2008-11-20}} {{verify source |date=September 2019}}</ref> This [[home remedy]] is not supported by any science, although it is possible that the act of rubbing may act as a distracting [[counterstimulation]], or that belief in the dock's effect may provide a [[placebo effect]].<ref>{{cite news |last1=Hopcroft |first1=Keith |title=Home remedies: dock leaves for nettle stings |url=https://www.thetimes.com/article/home-remedies-dock-leaves-for-nettle-stings-gk075bw6b3c |access-date=29 August 2020 |date=10 September 2005 |language=en}}</ref>

==Fossil record==
Several [[fossil]] fruits of ''Rumex'' sp. have been described from [[middle Miocene]] [[strata]] of the Fasterholt area near [[Silkeborg]] in Central [[Jutland]], [[Denmark]].<ref>{{cite journal |title=Angiosperm Fruits and Seeds from the Middle Miocene of Jutland (Denmark) |first=Else Marie |last=Friis |author-link=Else Marie Friis |journal=The Royal Danish Academy of Sciences and Letters |volume=24 |issue=3 |year=1985}}</ref>
{{clear}} One [[fossil]] fruit of a ''Rumex'' species has been extracted from a [[borehole]] sample of the [[Middle Miocene]] fresh water deposits in [[Nowy Sacz]] Basin, [[West Carpathians]], [[Poland]].
