Template:Short description Template:Automatic taxobox
The genus Fagopyrum is in the flowering plant family Polygonaceae. It includes some important food plants, such as F. esculentum (buckwheat) and F. tataricum (Tartary buckwheat). The genus is native to the Indian subcontinent, much of Indochina, central and southeastern China, and central and eastern tropical Africa.<ref name = POWO_331606-2/> Species have been widely introduced elsewhere, throughout the Holarctic and parts of Africa and South America.<ref name=POWO_331606-2/>
Description
Fagopyrum contains 30 species of plants,<ref name=POWO_331606-2/> including two important crop plants, buckwheat (Fagopyrum esculentum), and Fagopyrum tataricum (Tartary buckwheat). The two have similar uses, and are classed as pseudocereals, because they are used in the same way as cereals but do not belong to the grass family Poaceae.
Within Fagopyrum, the cultivated species are in the Cymosum group, including Fagopyrum cymosum or perennial buckwheat,<ref>PFAF Plant Database: Fagopyrum dibotrys (Perennial Buckwheat)</ref> the artificial hybrid Fagopyrum × giganteum,<ref name=ChenHuanLiYang18>Template:Cite journal</ref> and Fagopyrum homotropicum.<ref>Template:Cite journal</ref>
This genus has five-petaled flowers arranged in a compound raceme that produces laterally flowered cymose clusters.<ref>Template:Cite journal</ref>
