A list of absent family subgroups in Brazil, in Brazilian families with partially or fully stable classification. 59 families listed. Only clades at tribe level (or equivalent) or higher were highlighted (except Apocynaceae), and the distributions indicated refer only within South America. The numbers in each subgroup are based mainly on SSAA (SEE) and do not necessarily reflect the increase in the number of species from other sources or since them.
