Figures & data
Figure 1. Maximum-likelihood tree of Orchidaceae species based on the whole chloroplast genome sequences with Goodyera schlechtendaliana as outgroup. Numbers near the nodes represent ML bootstrap values. Oxystophyllum changjiangense is highlighted in red. The contents in parentheses are accession numbers of chloroplast genomes. Oxystophyllum changjiangense is sister to Phaius tancarvilleae with 100% support.
