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. [4] [5] [6] [7] [8] [9] 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). [10] The consensus agreed to the change, which was fully implemented in 2017. [3] It has the following clade-based definition:

Contents

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. [3]

Many genera show unique palynology. [11] [12]
