Phylogeny of the clusioid clade (Malpighiales): evidence from the plastid and mitochondrial genomes.

We present the first taxon-rich mutligene phylogeny of the clusioid clade (Malpighiales). The clusioids are widely distributed across the tropics and represent five families, 87 genera and ~2,000 species (i.e., Bonnetiaceae, Calophyllaceae, Clusiaceae, Hypericaceae, and Podostemaceae). Our phylogenetic analyses of plastid (matK, ndhF, and rbcL) and mitochondrial (matR) genes included nearly 200 clusioid species sampled across all major clusioid lineages. Our results provide a very well resolved phylogeny of the broad clusioid clade. They confirm previous findings that Clusiaceae are not monphyletic and reveal that several genera are not monophyletic as presently circumscribed. We discuss the taxonomic, morphological, and biogeographical implications of these results.
