Molecular Phylogenetics of the Dragon’s Blood Croton Section Cyclostigma (Euphorbiaceae): A Polyphyletic Assemblage Unraveled

The phylogenetic relationships of Croton section Cyclostigma sensu Webster were examined using nuclear ribosomal ITS and plastid spacer trnL–F sequences from 48 of the 63 species in the group, including members of the four recognized subsections and representing the group’s full morphological and ge...
