FIGURE 3. Bayesian maximum clade reliability trees based on combined nuclear At103 and chloroplast rps16, trnL-F datasets for Dracaena, Sansevieria, and selected outgroups.

Bold branches indicate strong support, interpreted as ≥ 70 BS and ≥ 95 PP. Long branches were shortened by half their length (indicated by \\).
