To measure the richness and composition of the taxa, based on the checklist, the number of genera and species of Malpighiaceae present in the most representative state in terms of number of collections were quantified. The total 2818 records were distributed in 110 species, grouped in 21 genera being Byrsonima Rich. ex Kunth, the most representative in number of species with (35) and in records with (1617).
