Podostemaceae are a family of ecologically and morphologically unusual aquatic angiosperms. The distribution maps of Asian Podostemaceae are provided here using results of recent studies, and a biogeographical scenario is proposed based on molecular phylogenetic and distributional data. In the scenario, Podostemaceae or at least Podostemoideae and Weddellinoideae originated in Gondwanaland. Tristichoideae diversified in tropical Asia, with one species migrating westward to Africa and then to South America. Weddellinoideae remained in South America. Podostemoideae diversified first in tropical America and reiterated westward migrations and radiations in Africa with Madagascar and then in Asia. Africa is a passageway for the westward and eastward migrations of the two families.
