Included here is the Atlantic coast of Africa from southwestern Gambia to eastern Ghana as far as about zero degrees longitude.
Of the endemic and near endemic vascular plants so far recorded there are about 730 species in 366 genera and 98 families. There are 55 endemic genera (marked red) but no endemic families. However, Dioncophyllaceae is endemic to western Africa, Achariaceae and Thomandersiaceae are endemic to Africa and Ancistrocladaceae is confined to Old World tropics. Of some biogeographic interest the endemic genus Maschalocephalus is the only Old World genus of the American family Rapateaceae and the endemic species Pitcairnia felicina is the only Old World species of the American family Bromeliaceae.
