is a rare and endangered species of the Sapindaceae with a very restricted distribution in Sichuan, China. In this study, the complete chloroplast genome of was characterized by assembly using high-throughput sequencing. The chloroplast genome was 155,702 bp in length; it contained a large single copy region (85,890 bp) and a small single copy region (18,100 bp), which were separated by a pair of 25,856-bp inverted repeat regions. A total of 128 genes were predicted, including 83 protein-coding genes, 37 tRNA genes, and eight rRNA genes. A phylogenetic analysis of 23 chloroplast genome sequences from the genus revealed that was closely related to .
是无患子科一种珍稀濒危物种，在中国四川分布极为有限。在本研究中，通过高通量测序组装对其完整叶绿体基因组进行了表征。叶绿体基因组长度为155,702 bp；它包含一个大单拷贝区域（85,890 bp）和一个小单拷贝区域（18,100 bp），这两个区域由一对25,856-bp的反向重复区域隔开。共预测到128个基因，包括83个蛋白质编码基因、37个tRNA基因和8个rRNA基因。对该属23个叶绿体基因组序列的系统发育分析表明，与关系密切。
