This clade is composed of four genera, two of which were traditionally assigned to the tribe Dalbergieae (Vatairea and Vataireopsis) and two of which were traditionally assigned to the tribe Sophoreae (Luetzelburgia and Sweetia), mainly on the basis of flower morphology.[5][6] However, recent molecular phylogenetic analyses circumscribed these four genera into a strongly supported monophyletic clade.[3][4][7] The name of this clade is informal and is not assumed to have any particular taxonomic rank like the names authorized by the ICBN or the ICPN.[2] The clade is defined as:
