Elaeis guineensis 1993. Elaeis guineensis Elaeis guineensis is a species of palm commonly called African oil palm or macaw-fat. It is the principal source of palm oil. It is native to west and southwest Africa, specifically the area between Angola and The Gambia; the species name "guineensis" refers to the name for the area, Guinea, and not the modern country which now bears that name. The species is also now naturalised in Madagascar, Sri Lanka, Malaysia, Indonesia, Central America, the West Indies and several islands in the Indian and Pacific Oceans. The closely related American oil palm "Elaeis oleifera" and a more
Phytomonas more economically significant crops, namely coconut ("Cocos nucifera") and oil palm ("Elaeis guineensis"). Finally, in 1982, Dollet successfully cultivated trypanosomatids "in vitro", which allowed for the isolation of "Phytomonas" in 24 different plant families from across the globe. While there has been recent genetic work done on "Phytomonas" species, genome level analysis is limited compared to the genome data available for disease causing trypanosomatids in animals and humans, especially "Trypanosoma cruzi", "Trypanosoma brucei", and "Leishmania major". In 2015, "Phytomonas nordicus" was found to be a part of the generally heteroxenous "Phytomonas" genus, despite it being a monoxenous parasite of the
