Premise of the study: The clusioid clade includes five families (i.e., Bonnetiaceae, Calophyllaceae, Clusiaceae sensu stricto [s.s.], Hypericaceae, and Podostemaceae) represented by 91 genera and ~1,900 species. Species in this clade form a conspicuous element of tropical forests worldwide and are important in horticulture, timber production, and pharmacology. To clarify phylogenetic uncertainty in the group, we conducted a multilocus phylogenetic analysis of the clusioids with greatly improved taxon sampling compared to previous studies. • Methods: We conducted phylogenetic analyses of plastid (matK, ndhF, and rbcL) and mitochondrial (matR) nucleotide sequence data using parsimony, maximum likelihood, and Bayesian inference. Our combined data set included ~200 species representing all major clusioid subclades identified in previous studies, plus numerous species spanning the taxonomic, morphological, and biogeographic breadth of the clusioid clade. • Key results: Our analyses indicate that the genera Tovomita (Clusiaceae s.s.); Harungana and Hypericum (Hypericaceae); and Ledermanniella s.s. and Zeylanidium (Podostemaceae) are not monophyletic. In addition, we place four genera that have not been included in any molecular study: Ceratolacis, Diamantina, and Griffithella (Podostemaceae), and Santomasia (Hypericaceae). Finally, our results indicate that Lianthus, Santomasia, Thornea, and Triadenum can be safely merged into Hypericum (Hypericaceae). • Conclusions: We present the first well-resolved, taxon-rich phylogeny of the clusioid clade. Taxon sampling and resolution within the clade are greatly improved compared to previous studies and provide a strong basis for improving the classification of the group. In addition, our phylogeny will form the foundation of future work investigating the biogeography of tropical angiosperms with Gondwanan distributions.
