The traditional family (Salicaceae sensu stricto) included the willows, poplars.
Genetic studies summarized by the Angiosperm Phylogeny Group (APG) have greatly expanded the circumscription of the family to contain 56 genera and about 1220 species, including the tropical Scyphostegiaceae and many of the former Flacourtiaceae.
Recognized to be closely related to the Violaceae and Passifloraceae, the family is placed by the APG in the order Malpighiales.
[7][8] Members of the family often have flowers which are reduced and inconspicuous, and all have ovaries that are superior or half-inferior with parietal placentation.
