Abstract:This paper deals with the origin and evolution of Litsea genera group (Laureae) in Lauraceae. It regarded that this group is originated at the southern part of Laurasia, northern part of Gondwana and the tropical coast area of Tethys sea not earlier than mid-Cretaceous. The pa-rallel evolution occurred in this natural genera group. The genera Litsea and Lindera, the nucleus of this genera group, are probably sympatrically originated from the common ancestor. The range from South China to Indo-Malaysia is probably the center of origin and speciation of these two genera, and from there they migrated into Tropical America and Australasia. The other genera of this genera group may be differentiated from this nucleus of the genera group.
