is a rare orchid species of the tribe Malaxideae mainly distributed in tropical Asia. This is the only species of the genus Thouars which has been reported to occur in China. Despite the importance of this genus, previous molecular studies based on few markers have resulted in limited phylogenetic resolution. With the decline of habitats, the wild population of has decreased in recent years. In this study, we first reported the complete chloroplast (cp) genome of . The entire cp genome was determined to be 158,056 bp in length with overall GC content of 36.9%, containing a pair of inverted repeat regions (IRs) of 27,006 bp, separated by a large single-copy (LSC, 86,280 bp) and a small single-copy (SSC, 17,764 bp). A total of 133 unique genes were annotated, including 87 protein-coding genes, 38 tRNA genes, and eight rRNA genes. The phylogenetic tree indicated that was a sister group of the genus and the epiphytic alliance with strong support.
