摘要：The relationships among sections and species within each section in the genus Populus have attracted much attention from taxonomists and biologists. In this paper, we provide an overview of the current state of Populus phylogenetics and discuss the origin of some hybrid species. There has been some controversy surrounding the origin of the genus Populus in North America and subsequent dispersal and differentiation in other parts of the world. We present the most plausible scenario based on phylogenetic analysis and fossil records. Sections Abaso, Turanga and Populus are all monophyletic, whereas sections Aigeiros, Tacamahaca and Leucoidesshow some degree of polyphyly. Sections Abaso and Turanga are relatively primitive lineages in Populus. With the accumulation of sequencing data and new analytical tools, it will be possible to investigate more complicated issues concerning genus Populus within a phylogenetic framework.
