Simplified phylogenetic tree based on the best-scoring maximum likelihood phylogram of Chung et al. (). Clades of sect. Petermannia, sect. Baryandra and PLA-SPH (sections Platycentrum and Sphenanthera) are compressed for simplicity. Clade supports with less than 50%/0.5 in likelihood bootstrap (LB), parsimony bootstrap (PB), and posterior probability (PP) of Bayesian analyses are indicated by dashed branches, while thick branches denote those present in the strict consensus tree of maximum parsimony analysis and PP ≥0.95. Sectional abbreviations: ALI: Alicida, AUG: Augustia, DIP: Diploclinium, HAA: Haagea, PAR: Parvibegonia, REI: Reichenheimia, RID: Ridleyella, UA: unassigned.
