Simplified maximum likelihood tree of Cynanchum based on two nuclear regions (nrETS and nrITS) and three plastid markers (rps16 and trnL introns, and trnL-F spacer). Bootstrap support values are given for each node. See Suppl. material 3 for maximum likelihood tree. Clade designations follow those of Khanum et al. (2016) and names in parentheses are the corresponding names that were used in Khanum et al. (2016).
