Caesalpinioideae is abotanical name at the rank ofsubfamily, placed in the large familyFabaceae orLeguminosae. Its name is formed from the generic nameCaesalpinia. It is known also as the peacock flower subfamily.[5] The Caesalpinioideae are mainly trees distributed in the moisttropics, but include such temperate species as the honeylocust (Gleditsia triacanthos) and Kentucky coffeetree (Gymnocladus dioicus). It has the following clade-based definition:
Caesalpinioideae, as it was traditionallycircumscribed, wasparaphyletic. Severalmolecular phylogenies in the early 2000s showed that the other two subfamilies ofFabaceae (Faboideae andMimosoideae) were both nested within Caesalpinioideae.[7][8][9][10] Consequently, the subfamilies of Fabaceae were reorganized to make them monophyletic.[6] Caesalpinioideae, as currently defined, contains the following subclades:[8]
