has been classified as a national second-class protected orchid species in China. In this study, we report and characterize the complete chloroplast (cp) genome sequence of . in an effort to provide genomic resources useful for promoting its conservation and systematic research. The complete genome is 159,010 bp in length and the overall GC content is 43.3%. The cp genome sequence has a typical quadripartite structure, comprising two inverted repeats (IRA and IRB) regions, which are separated by a small singlecopy (SSC) region and a large singlecopy (LSC) region. Moreover, a total of 135 functional genes were annotated, including 89 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. The phylogenetic analysis recovered a close relationship between and , and both species are placed within the tribe Arethuseae (Orchidaceae).
在中国已被列为国家二级保护兰科植物物种。在本研究中，我们报道并描述了[具体物种名称]的完整叶绿体（cp）基因组序列，旨在提供有助于促进其保护和系统研究的基因组资源。完整基因组长度为159,010 bp，总体GC含量为43.3%。cp基因组序列具有典型的四分体结构，由两个反向重复（IRA和IRB）区域组成，这两个区域被一个小单拷贝（SSC）区域和一个大单拷贝（LSC）区域隔开。此外，总共注释了135个功能基因，包括89个蛋白质编码基因、38个tRNA基因和8个rRNA基因。系统发育分析表明[具体物种名称]与[另一物种名称]关系密切且这两个物种都属于万代兰族（兰科）。
