| Summary: | Syzygium forrestii Merr. et Perry is an evergreen broad-leaved tree, 8–15 metres tall. It is mainly distributed in the Southwest of China (Nu river valley to Xishuangbanna area), growing from 800 to 2400 metres above sea level. It grows in the evergreen broad-leaved forest and the hillside shrubbery. It is an endemic plant species in China. At present, it has not been artificially introduced and cultivated. However, its complete plastome information and systematic position is still unknown. Here we report and characterize the complete plastid genome sequence of S. forrestii in an effort to provide genomic resources useful for promoting its conservation and systematic research. The complete plastome is 159,996 bp in length and contains the typical structure and gene content of angiosperm plastome, including two inverted repeat (IR) regions of 26,414 bp, a large single-copy (LSC) region of 88,560 bp and a small single-copy (SSC) region of 18,608 bp. The plastome contains 115 genes, consisting of 81 unique protein-coding genes, 30 unique tRNA gene and 4 unique rRNA genes (5S rRNA, 4.5S rRNA, 23S rRNA and 16S rRNA). The overall A/T content in the plastome of S. forrestii is 63.10%. The complete plastome sequence of S. forrestii will provide a useful resource for the conservation genetics of this species as well as for the phylogenetic studies of Myrtaceae.
