(H. G. Reichenbach) Pfitzer is an endangered and threatened orchid species in China. The genetic and molecular data of this orchid species is deficient. With the aim to identify appropriate chloroplast markers for the use in a conservation biology study, the complete chloroplast genome of was reported. We found that the chloroplast genome of is 157,292 bp in length, containing a large single-copy region of 87,252 bp, a small single-copy region of 1828 bp, and a pair of inverted repeats of 34,106 bp. Genome annotation predicted 105 unique genes, including 71 protein-coding genes, 30 tRNAs, and four rRNAs. Fourteen genes contained one intron and two genes (P and 3) had two introns. The GC content of the was 35.8%. Phylogenetic analysis indicated was closely related to .
（H.G.赖兴巴赫）独花兰是中国一种濒危且受威胁的兰花物种。该兰花物种的遗传和分子数据匮乏。为了鉴定适用于保护生物学研究的叶绿体标记，报道了独花兰的完整叶绿体基因组。我们发现独花兰的叶绿体基因组长度为157,292 bp，包含一个87,252 bp的大单拷贝区域、一个1828 bp的小单拷贝区域以及一对34,106 bp的反向重复序列。基因组注释预测有105个独特基因，包括71个蛋白质编码基因、30个tRNA和4个rRNA。14个基因含有一个内含子，两个基因（P和3）有两个内含子。独花兰的GC含量为35.8%。系统发育分析表明独花兰与[具体物种]关系密切。
