This study updates the floristic realms of the world by integrating global distributions and mega-phylogenies of 12,664 angiosperm genera. Eight realms and 16 sub-realms are identified, most of which have formed since the Paleogene, and their formation is dominated by geographic isolation induced by plate tectonics rather than current or historical climate.
