Maximum Likelihood (ML) and Bayesian Inference (BI) phylogenetic trees based on whole cp genomes of 24 samples. Paspalum paniculatum was set as the outgroup. The numbers above the branches represent ML bootstrap values/BI posterior probabilities. The shared morphological characteristics for each of the five clades were shown next to each species in the way of hand-drawn illustrations, and the dry leaves of “ZHDD” bought from TCM pharmacy were shown next to “Zi Hua Di Ding1, 2”. The hand-drawn illustrations credits: Dong-Ling Cao. In the mature period with dimorphic leaf blades, i.e., smaller triangular-ovate for the lower leaf blades and longer oblong-ovate for the upper leaf blades was shown next to V. philippica. For section Viola, the fruit is the globose capsule. For section Trigonocarpae, the stigmas are clavate, slightly curved forward at the base, and the apex is uncinate or papillose; For section Bilobatae, the stigmas are 2-lobed, thick, with a conspicuous stigma hole; For section Pinnatae, the leaf blades are lobe; For section Adnatae, the length of stipules adnate with petioles is longer than one-half length of stipules
