Sweetia fruticosa is a species of flowering plants in the legume family, Fabaceae. It is a tree native to eastern, southern, and west-central Brazil, Bolivia, Paraguay, and northeastern Argentina.[2] It is the only member of the genus Sweetia (though some sources also include Sweetia atrata Mohlenbr.).[3][4] It belongs to the subfamily Faboideae. It was traditionally assigned to the tribe Sophoreae, mainly on the basis of flower morphology;[5] recent molecular phylogenetic analyses assignedSweetia fruticosa into an informal, monophyletic clade called the "vataireoids".[6][7]
