Consensus phylogenetic tree reconstructed by ML and BI analysis based on 55 protein-coding sequences (CDS) of 10 species, with Colocasia esculenta and Ottelia cordata as outgroups. Asterisks near the branches indicate bootstrap support (BS) percentages obtained from maximum likelihood inference and posterior probabilities (PP) obtained from Bayesian analysis (BS/PP). Those nodes with BS = 100% and PP = 1.00 were shown with asterisks.
