The phylogenetic trees of 23 Cuscuta species and Ipomoea purpurea as determined from different data based on protein-coding sequences (left) and the complete chloroplast genome sequences (right). The support values are shown for nodes as maximum likelihood bootstrap (approach branches). The species with the same color belong to the same subgenus. Brown, purple, orange and blue represent the subgenera Monogynella, Cuscuta, Pachystigma, and Grammica, respectively. * indicates that the chloroplast genomes of these Cuscuta species were sequenced in this study
