Reestablishment of Protium cordatum (Burseraceae) based on integrative taxonomy
Species delimitation remains a challenge worldwide, but especially in biodiversity hotspots such as the Amazon. Here, we use an integrative taxonomic approach that combines data from morphology, phylogenomics, and leaf spectroscopy to clarify the species limits within the Protium heptaphyllum specie...
