Fig. 7From: An integrated study of Violae Herba (Viola philippica) and five adulterants by morphology, chemical compositions and chloroplast genomes: insights into its certified plant originPhylogenetic tree based on the cp genomes of 17 Viola species using maximum likelihood (ML) and Bayesian inferences (BI) methods. Passiflora edulis was used as outgroup. Numbers besides the nodes represent ML bootstrap support (BS) values and BI posterior probabilities (PP) values. The legend on the right shows the Section-Subsection taxonomic synopsis and the corresponding evolution of stigmaBack to article page
