Protium acrense, P. cerradicola and P. yanachagae are described and illustrated, and a key to the twelve species of Protium sect. Tetragastris is provided. Recent botanical exploration is revealing that the Andes constitute a minor center of the Burseraceae diversity that has yielded at least one new species in this section (described here). The other two, now that they have been distinguished from P. altissimum, segregate satisfactorily by geography and habitat.
