Sweetia fruticosa is a species of flowering plants in the legume family, Fabaceae and is the only member of the genus Sweetia (though some sources also include Sweetia atrata Mohlenbr.).[1][2] It belongs to the subfamily Faboideae. It was traditionally assigned to the tribe Sophoreae, mainly on the basis of flower morphology;[3] recent molecular phylogenetic analyses assigned Sweetia fruticosa into an informal, monophyletic clade called the "vataireoids".[4][5]
