(Roxb.) is a subtropical plant under the family Rosaceae with high economic and medicinal value. The whole chloroplast genome of was sequenced to better understand its phylogenetic position relative to other Rosaceae species. The total length of the chloroplast genome was 159,270 bp, which was composed of a large single-copy (LSC) region of 87,362 bp, a small single-copy (SSC) region of 19,184 bp, and a pair of inverted repeats (IRs) with a length of 26,362 bp separated by LSC and SSC. The total G + C content of the whole chloroplast genome was 36.7%. Phylogenetic analysis of maximum likelihood (TVM + F+R2) was completed using 15 complete chloroplast genomes of Rosaceae species. The results of phylogenetic analysis show that sisterhood exists in with nine other species of .
（蔷薇科）是蔷薇科下的一种亚热带植物，具有很高的经济和药用价值。对其完整叶绿体基因组进行测序，以便更好地了解其相对于其他蔷薇科物种的系统发育位置。该叶绿体基因组全长159,270 bp，由一个87,362 bp的大单拷贝（LSC）区域、一个19,184 bp的小单拷贝（SSC）区域和一对长度为26,362 bp的反向重复序列（IRs）组成，LSC和SSC将其隔开。整个叶绿体基因组的总G+C含量为36.7%。使用15个蔷薇科物种的完整叶绿体基因组完成了最大似然法（TVM + F+R2）的系统发育分析。系统发育分析结果表明，它与其他九个物种存在姐妹关系。
