Monodora myristica

About

Monodora myristica, the calabash nutmeg or African nutmeg, is a tropical tree of the family Annonaceae or custard apple family of flowering plants. It is native to tropical Africa from Guinea Bissau in the west to Tanzania. In former times, its seeds were widely sold as an inexpensive nutmeg substitute. This is now less common outside its region of production. Other names of calabash nutmeg include Jamaican nutmeg, ehuru, ariwo, awerewa, ehiri, airama, African orchid nutmeg, muscadier de Calabash lubushi, and pebe or pebbe.
