Fagopyrum contains 15 to 16 species of plants, including two important crop plants, buckwheat (Fagopyrum esculentum), and Tartary buckwheat (or Fagopyrum tataricum). 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 dibotrys or perennial buckwheat (formerly Fagopyrum cymosum), Fagopyrum giganteum, and Fagopyrum homotropicum.
