Myrcia mesoamericana has distinct leaf morphology with strongly raised veins in the abaxial surface and no clearly typical sympodial branching. The calyx lobes are totally fused but open as an imperfect calyptra during anthesis. The inflorescence has sympodial branching at the base, typical of Myrcia sect. Calyptranthes . Phylogenetic analysis is desirable for more accurate placement of Myrcia mesoamericana inside Myrcia .
