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
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
