Abstract:Ficus and their species-specific pollinator wasps （Agaonidae） form a remarkable plant-insect obligate mutualism. The studies on co-evolution of them caused much attention to the classification of Ficus. For further study of the systematics and evolution of the genus, the present authors introduce the taxonomic history and some known classification systems in this review. In addition, some unresolved problems in Ficus taxonomy are discussed and some advices on the future study are given.
