Phylogeny of the Pinguicula species based on the Bayesian inference (BI), maximum likelihood (ML) and maximum parsimony (MP) analyses of the trnK/matK sequences. The numbers above the branches refer to the BI posterior probability and the ML bootstrap support, respectively, and below the MP, the bootstrap support. The animal silhouettes denote the pollinator for each species. ‘*’ indicates the homoplastic origin of the ornithophily for P. hemiepiphytica and P. laueana independently. ‘+’ or ‘–’ indicate the presence/absence of starch grains in the edible trichomes of the bee-/fly-pollinated species.
