The Chinese false tupelo, Camptotheca acuminata , is a Tertiary relict species with dramatically fragmented and declined populations. Here we characterized the complete chloroplast (cp) genome of C. acuminata using Illumina pair-end sequencing data. The C. acuminata cp genome was 157,806 bp in length, containing a pair of inverted repeats (IRs) of 25,771 bp which separated a large single copy region (LSC) of 87,504 bp and a small single copy region (SSC) of 18,760 bp. The genome contained 134 genes, including 88 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. Most of genes occurred as single-copy in the LSC or SSC, while 18 genes had two copies in the IRs. The GC content of C. acuminata cp genome is 37.8%. Phylogenomic analysis strongly supported the close relationship of C. acuminata and Davidia involucrata . This complete cp genome will be useful for further conservation genomics studies of C. acuminata .
