is a rare orchid species with extremely small populations, endemic to China. In this study, the complete chloroplast (cp) genome sequence and the genome features of were analyzed. The whole cp genome sequence of is 160,052 including a large single-copy region (LSC, 87,525 bp), a small single-copy region (SSC, 18,373 bp), and a pair of repeat regions (IRs, 27,077 bp, each). The contents of four bases in cpDNA were A (30.9%), C (18.9%), G (18.3%) and T (31.9%), respectively. The total content of GC is 37.1%. The cp genome contains 129 genes, consisting of 124 unique genes (78 protein-coding genes, 38 tRNAs, and 8 rRNAs). Phylogenetic analysis showed that nested with other spp. and was closely related to and .
是一种中国特有的、种群数量极少的珍稀兰花物种。在本研究中，分析了该物种的完整叶绿体（cp）基因组序列及基因组特征。该物种的完整cp基因组序列为160,052，包括一个大单拷贝区域（LSC，87,525 bp）、一个小单拷贝区域（SSC，18,373 bp）和一对重复区域（IRs，各27,077 bp）。cpDNA中四种碱基的含量分别为A（30.9%）、C（18.9%）、G（18.3%）和T（31.9%）。GC的总含量为37.1%。cp基因组包含129个基因，由124个独特基因组成（78个蛋白质编码基因、38个tRNA和8个rRNA）。系统发育分析表明，该物种与其他同属物种嵌套在一起，与[具体物种1]和[具体物种2]关系密切。
