Elaeis Elaeis Elaeis () is a genus of palms containing 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" referring to its country of origin) is the principal source of palm oil. It is native to west and southwest Africa, occurring between Angola and Gambia. The American oil palm "Elaeis oleifera" () is native to tropical Central and South America, and is used locally for oil production. Mature palms are single-stemmed, and can grow well over tall. The leaves are pinnate, and reach
Elaeis guineensis oil palms to stop decay. The spread likely is by spores rather than roots. The knowledge gained can be employed in the rapid degradation of oil palm waste on the plantation floor by inoculating suitable fungi, and/or treating the waste more appropriately (e.g. chipping and spreading over the floor rather than windrowing). Endophytic bacteria are organisms inhabiting plant organs that at some time in their life cycles can colonize the internal plant tissues without causing apparent harm to the host. Introducing endophytic bacteria to the roots to control plant disease is to manipulate the indigenous bacterial communities of the roots
