in many molecular phylogenies. At the 6th International Legume Conference, the Legume Phylogeny Working Group proposed elevating the tribe Cercidae to the level of subfamily within the Leguminosae (Fabaceae). The consensus agreed to the change, which was fully implemented in 2017. It has the following clade-based definition:
The most inclusive crown clade containing '' Cercis canadensis'' L. and '' Bauhinia divaricata'' L. but not '' Poeppigia procera'' C.Presl, '' Duparquetia orchidacea'' Baill., or '' Bobgunnia fistuloides'' (Harms) J.H.Kirkbr. & Wiersema.Many genera show unique
