'''''Arachis''''' is a [[genus]] of about 70 [[species]] of annual and perennial [[flowering plant]]s in the family ([[Fabaceae]]), native to South America, and was recently assigned to the informal [[monophyly|monophyletic]] ''Pterocarpus'' clade of the [[Dalbergieae]].<ref name="Lavin" /><ref name="Cardoso" /> At least one species, the [[peanut]] (''Arachis hypogaea''), is a major [[food crop]] species of global importance; some of the other species are cultivated for food to a small extent in South America. Other species such as ''[[Arachis pintoi|A. pintoi]]'' are cultivated worldwide as forage and soil conditioner plants, with the leaves providing high-protein feed for grazing livestock and a nitrogen source in [[agroforestry]] and [[permaculture]] systems.

''Arachis'' species, including the peanut, are used as food plants by some [[Lepidoptera]] species, including the [[flame shoulder]], [[Nutmeg (moth)|nutmeg]], and [[turnip moth]].<ref>{{cite web|url= https://www.nhm.ac.uk/our-science/data/hostplants/search/list.dsml?searchPageURL=index.dsml&Family=noctuidae&PGenus=arachis |title=HOSTS - a Database of the World's Lepidopteran Hostplants |date=2023 |publisher=The Natural History Museum, London |doi=10.5519/havt50xw |access-date=2020-06-14 |last1=Robinson |first1=Gaden S. |last2=Ackery |first2=Phillip R. |last3=Kitching |first3=Ian |last4=Beccaloni |first4=George W. |last5=Hernández |first5=Luis M. }}</ref>
