var. is classified as subgenus of Meliaceae family, which belongs to a large deciduous tree species. It is also a kind of precious timber tree species and has a certain medicinal value. Here, the first complete chloroplast genome (cpDNA) sequence of var. was determined using the Illumina sequencing platform. The cpDNA genome is 159,481 bp in length, containing a large single-copy region (LSC) of 87,176 bp and a small single-copy region (SSC) of 18,381 bp, which were separated by a pair of inverted repeats (IRs) regions of 26,962 bp. The genome contains 138 genes, including 90 protein-coding genes, eight ribosomal RNA genes, and 40 transfer RNA genes. The phylogenetic analysis based on 19 cpDNA genomes showed a close relationship with .
变种被归类为楝科的亚属，属于大型落叶树种。它也是一种珍贵的用材树种，具有一定的药用价值。在此，利用Illumina测序平台测定了变种的首个完整叶绿体基因组（cpDNA）序列。cpDNA基因组长度为159,481 bp，包含一个87,176 bp的大单拷贝区域（LSC）和一个18,381 bp的小单拷贝区域（SSC），它们被一对26,962 bp的反向重复（IRs）区域隔开。该基因组包含138个基因，包括90个蛋白质编码基因、8个核糖体RNA基因和40个转移RNA基因。基于19个cpDNA基因组的系统发育分析表明与有密切关系。
