摘要	The genus Phoebe (Lauraceae) includes about 90 evergreen tree species that are an ideal source of timber. Habitat destruction and deforestation have resulted in most of them being endemic to China. The accurate identification of endangered Phoebe species in China is necessary for their conservation. Chloroplast genome sequences can play an important role in species identification. In this study, comparative chloroplast genome analyses were conducted on diverse Phoebe species that are primarily distributed in China. Despite the conserved nature of chloroplast genomes, we detected some highly divergent intergenic regions (petA-psbE, ndhF-rpl32, and psbM-trnD-GUC) as well as three highly divergent genes (rbcL, ycf1, and ycf2) that have potential applications in phylogenetics and evolutionary analysis. The phylogenetic analysis indicated that various Phoebe species in China were divided into three clades. The complete chloroplast genome was better suited for phylogenetic analysis of Phoebe species. In addition, based on the phylogeographical analysis of Phoebe species in China, we inferred that the Phoebe species in China first originated in Yunnan and then spread to other southern areas of the Yangtze River. The results of this research will add to existing case studies on the phylogenetic analysis of Phoebe species and have the potential to contribute to the conservation of Phoebe species that are in danger of extinction.
