The genus Acrocomia (Arecaceae) is widely distributed in the Neotropics, without consensus on the number of species. The arboreal species are explored in their native countries. To subsidize better use of the observed variation in fruits of different species for product extraction, taxonomy, conservation and genetic improvement, our objective was to characterize biometrically the fruits and anatomically the mesocarp from natural populations of A. aculeata, A. intumescens and A. totai. We observed different colors of epicarp and mesocarp in A. aculeata and A. totai, while the fruits of A. intumescens were light green or yellowish. The fruits of A. aculeata showed diameter considered large (3.9-4.6 cm) and the highest dry mass (26.3-33.5 g), A. intumescens presented intermediate diameter (3.1–3.9 cm) and mass (11.5-18.8 g), and A. totai had the smallest diameter (2.2-3.0 cm) and mass (4.1-11.4 g). The morphoanatomical analysis of the mesocarp did not distinguish the three species. However, it revealed the presence of useful compounds for human consumption and with economic potential, such as oil in the parenchyma cells, mucilage, starch and phenolic compounds. We concluded that the mesocarp anatomy is not useful for taxonomy, but the biometric variation is, as well as variation within species can be applicable in conservation and genetic improvement.
