In recent molecular phylogenetic work on tribe Protieae (Burseraceae) with thorough sampling, the major well-supported clades show remarkable congruence with infrageneric classifications based on morphology, but the results call for synonymizing Crepidospermum and Tetragastris with Protium, thereby making Protieae monophyletic and monogeneric under the name Protium. The necessary synonymies and a brief diagnosis for each of the eight sections of Protium are provided, and these new combinations are made: Protium balsamiferum, P. catuaba, P. chagrense, P. herbertii, P. mucronatum, P. occhionii, and P. rhynchophyllum.
