Characterization of the complete chloroplast genome of Korean endemic, (Orchidaceae).

(Orchidaceae), endemic to South Korea, is a perennial herb and its local population sizes are declined because of the destruction caused by human activity and the invasion of exotic species in their habitats. Here, we report the complete chloroplast (cp) genome sequence of , which will provide valuable information for its biological conservation and future studies for the cp genome evolution of endemic plants on the Korean Peninsula. The cp genome of is 155,708 bp in length, containing a large single-copy region of 85,131 bp and a small single-copy region of 17,659 bp which are separated by a pair of inverted repeats of 26,459 bp. The cp genome encodes 131 genes, of which 113 are unique, including 79 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. The overall GC content is 36.6%, which is consistent with the species previously reported. Our phylogenomic analyses identified the sister relationship between and in the genus.
