Maximum likelihood tree based on chloroplast ndhF and nuclear 26S sequences. Bootstrap percentage ≥50 are labeled above branches. Bayesian posterior probability values ≥0.75 are labeled under branches. Linages obtained in this study are followed by collection sites (Country: locality), collectors and original collection numbers. All Taiwanese samples of Broussonetia monoica (collection sites in green) would be identified as B. kaempferi var. australis sensu Suzuki (1934)
