Fagopyrum tataricum, also known as
Tartary buckwheat,
duckwheat,
India buckwheat,
India wheat,
green buckwheat,
ku qiao, or
bitter buckwheat, is a
domesticated food
plant in the
genus Fagopyrum in the family
Polygonaceae. With another species in the same
genus,
common buckwheat, it is often counted as a
cereal, but unlike the true cereals the buckwheats are not members of the
grass family. Thus they are not related to true
wheat. Tartary buckwheat is bitterer, but contains more
rutin than common buckwheat. It also contains
quercitrin.
