The dioecious relic is a tertiary relict and only species of its genus within the family Sapindaceae. Using an Illumina platform, we sequenced its complete chloroplast (cp) genome. Our study reveals that has a typical cp genome of 158,537 bp in length, comprised of a large single-copy region (LSC) of 86,693 bp, a small single-copy region (SSC) of 18,012 bp, and two inverted repeat regions (IRs) of 26,916 bp, respectively. A total of 137 genes, 89 of which are protein-coding genes, 40 tRNA genes, 8 rRNA genes were identified. The overall GC content of the plastome is 38.0%. Phylogenetic analysis indicates that is closely related to the species of .
这种雌雄异株的残遗植物是第三纪残遗植物，也是无患子科中其属的唯一物种。我们利用Illumina平台对其完整的叶绿体（cp）基因组进行了测序。我们的研究表明，其cp基因组典型长度为158,537 bp，由一个86,693 bp的大单拷贝区域（LSC）、一个18,012 bp的小单拷贝区域（SSC）和两个分别为26,916 bp的反向重复区域（IR）组成。共鉴定出137个基因，其中89个为蛋白质编码基因、40个tRNA基因、8个rRNA基因。质体基因组的总体GC含量为38.0%。系统发育分析表明，它与[具体物种]的物种密切相关。
