Fig. 4From: Plastome phylogenomics and morphological traits analyses provide new insights into the phylogenetic position, species delimitation and speciation of Triplostegia (Caprifoliaceae)a Unrooted neighbour-joining (NJ) tree of Triplostegia based on the P-distance calculated from three highly variable plastid DNA regions (ndhf, ndhf-trnN, rpoB-trnC) and nuclear ITS sequences. b Neighbor-net analysis of Triplostegia based on complete chloroplast genome and nrNDA sequences. Bootstrap values (based on 1000 replicates) are indicated along the branches for each clustersBack to article page
