Phylogenetic relationships <strong>of</strong> <strong>Hedyotis</strong> s.str. The two small genera Metabolos (2 spp.) and Pleiocraterium (4 spp.) are both resolved wellinside <strong>Hedyotis</strong> s.str. The results also indicate biogeographical patterns in <strong>Hedyotis</strong> s.str. Species from the Indian subcontinent are resolved intwo different groups, and three different groups with primarily Chinese distributions are indicated. The tree is a 50% majority-rule consensustree from a Bayesian Markov chain Monte Carlo (MCMC) analysis <strong>of</strong> a combined dataset <strong>of</strong> plastid (rps16, petD) and nuclear (ITS, ETS) data.Bayesian posterior probabilities are indicated at the nodes.Version <strong>of</strong> Record (identical to print version).361
