Diversification in species complexes: Tests of species origin and delimitation in the Bursera simaruba clade of tropical trees (Burseraceae)

► Morphologically variable and widely distributed B. simaruba is a single valid species. ► Satellites resemble B. simaruba due to evolutionary convergence or parallelism. ► Molecular phylogeny of the complex highlights potential synonymy and new species. ► Molecular phylogeny points out morphological characters in need of revision. ► Ecological characters allow differentiation between satellite species.
