is an Endangered medicinal plant in southern China. In this study, the complete chloroplast genome sequence of was characterized by de novo assembly. The length of the whole chloroplast genome was 158,537 bp, containing a large single copy region (LSC) of 86,250 bp and a small single copy region (SSC) of 18,287 bp, which were separated by a pair of 27,000 bp inverted repeat regions (IRs). The sequence contains 114 unique genes, including 30 tRNA, 4 rRNA, and 80 protein-coding genes. The overall GC content of the chloroplast genome is 38.4% and those in the LSC, SSC, and IR regions are 36.6, 33.2, and 42.9%, respectively. The phylogenetic analysis based on reported chloroplast sequences of Rutaceae showed that is sister to , consisting a monophyletic group, and that is closely related to .
是中国南方一种濒危药用植物。在本研究中，通过从头组装对其完整叶绿体基因组序列进行了表征。整个叶绿体基因组长度为158,537bp，包含一个86,250bp的大单拷贝区域（LSC）和一个18,287bp的小单拷贝区域（SSC），它们被一对27,000bp的反向重复区域（IR）隔开。该序列包含114个独特基因，包括30个tRNA、4个rRNA和80个蛋白质编码基因。叶绿体基因组的总体GC含量为38.4%，LSC、SSC和IR区域的GC含量分别为36.6%、33.2%和42.9%。基于芸香科已报道叶绿体序列的系统发育分析表明，与是姐妹关系，构成一个单系类群，并且与密切相关。
