Elaeis
Elaeis (from Greek 'oil') is a genus of palms with two species, called oil palms. They are used in commercial agriculture in the production of palm oil. The African oil palm Elaeis guineensis (the species name guineensis refers to its country of origin) is the main source of palm oil. It is native to west and southwest Africa. It can be found between Angola and Gambia. The American oil palm Elaeis oleifera (from Latin  oleifer 'oil-producing') is native to tropical Central and South America, and is used locally for oil production.
