Aframomum melegueta is a species in the ginger family, Zingiberaceae, and closely related to cardamom. Its seeds are used as a spice (ground or whole); it imparts a pungent, black-pepper-like flavor with hints of citrus. It is commonly known as grains of paradise, melegueta pepper, alligator pepper, Guinea grains, ossame, or fom wisa. The term Guinea pepper has also been used, but is most often applied to Xylopia aethiopica (grains of Selim).
It is native to West Africa, which is sometimes named the Pepper Coast (or Grain Coast) because of this commodity.
