摘要： Euphorbia hainanensis is a rare cliff top boskage, which has an important ecological and economic value. In this study, we sequenced its complete chloroplast (cp) genome using Illumina sequencing platform. The cp genome of E. hainanensis is a typical quadripartite structure with a length of 163,977 bp, which contained inverted repeats (IR) of 26,717 bp separated by a large single-copy (LSC) and a small single copy (SSC) of 92,771 bp and 17,772 bp, respectively. A total of 131 genes, 82 of which are protein coding genes, 39 tRNA genes, and eight rRNA genes were identified. The overall GC content of the plastome is 35.4% while the corresponding values of the LSC, SSC, and IR regions are 32.4%, 30.0%, and 42.4%, respectively. The phylogenetic analysis suggested that E. hainanensis was closely related to the species of E. esula.
