belongs to tribe Coelogninae in Orchidaceae distributed in Sichuan, Xizang, and Yunnan. Here, we report the first complete chloroplast (cp) genome and the cp genome features of The complete cp genome sequence of is 159,292 bp in length and presented a typical quadripartite structure including one large single-copy region (LSC, 87,515 bp), one small single-copy region (SSC, 20,999 bp), and two inverted repeat regions (IRs, 25,389 bp each). The cp genome encoded 141 genes, of which 108 were unique genes (80 protein-coding genes, 24 tRNAs, and 4 rRNAs). The phylogenetic relationships show that is sister to the species of the genus in tribe Coelogninae.
属于兰科勺兰亚族，分布于四川、西藏和云南。在此，我们报道了其首个完整叶绿体（cp）基因组及cp基因组特征。该物种的完整cp基因组序列长度为159,292 bp，呈现典型的四分体结构，包括一个大单拷贝区域（LSC，87,515 bp）、一个小单拷贝区域（SSC，20,999 bp）和两个反向重复区域（IRs，各25,389 bp）。cp基因组编码141个基因，其中108个为独特基因（80个蛋白质编码基因、24个tRNA和4个rRNA）。系统发育关系表明，该物种与勺兰亚族中某属的物种互为姐妹关系。
