Cercidoideae is a subfamily in the pea family, Fabaceae. Well-known members include Cercis (redbuds), including species widely cultivated as ornamental trees in the United States and Europe, Bauhinia, widely cultivated as an ornamental tree in tropical Asia, and Tylosema , a semi-woody genus of Africa. The subfamily occupies a basal position within the Fabaceae and is supported as monophyletic in many molecular phylogenies.[3][4][5][6][7][8] 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).[9] The consensus agreed to the change, which was fully implemented in 2017.[2] 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.[2]
Many genera show unique palynology.[10][11]
