(Rutaceae) is a small shrub (1-2 m tall) distributed in moist and shady places throughout evergreen broad-leaved forests having altitudes that range from 100 to 400 m in West Guangdong, Southeast Guangxi, Hainan province of China. It has been ranked as a near threatened (NT) species in China. Here, we report and characterize the complete plastid genome sequence of in an effort to provide genomic resources useful for its conservation. The complete plastome is 160,248 bp in length and contains the typical structure and gene content of angiosperm plastomes, including two inverted repeat (IR) regions of 27,151 bp, a large single-copy (LSC) region of 87,483 bp and a small single-copy (SSC) region of 18,463 bp. The plastome contains 110 genes, consisting of 77 unique protein-coding genes (ycf1 is a pseudogene), 29 unique tRNA genes, and 4 unique rRNA genes. The overall A/T content in the plastome of is 61.6%. Phylogenetic analyses were performed using the entire plastome, including spacers, introns, etc., and we determined that and were closely related. The complete plastome sequence of will provide a useful resource for the conservation genetics of this species as well as for the phylogenetic studies in Sapindales.
（芸香科）是一种小灌木（高1-2米），分布于中国广东西部、广西东南部、海南省海拔100至400米的常绿阔叶林的潮湿阴凉处。它在中国被列为近危（NT）物种。在此，我们报告并描述了[物种名称]的完整质体基因组序列，以期提供有助于其保护的基因组资源。完整的质体基因组长度为160,248 bp，包含被子植物质体基因组的典型结构和基因内容，包括两个27,151 bp的反向重复（IR）区域、一个87,483 bp的大单拷贝（LSC）区域和一个18,463 bp的小单拷贝（SSC）区域。质体基因组包含110个基因，由77个独特的蛋白质编码基因（ycf1是一个假基因）、29个独特的tRNA基因和4个独特的rRNA基因组成。[物种名称]质体基因组的总体A/T含量为61.6%。使用包括间隔区、内含子等在内的整个质体基因组进行系统发育分析，我们确定[物种名称]与[另一物种名称]密切相关。[物种名称]的完整质体基因组序列将为该物种的保护遗传学以及无患子目系统发育研究提供有用资源。
