2.1- Tribe Caesalpinieae + Overview Caesalpinieae is the tribe of the plant familyFabaceae (the family which includes the legumes). This tribe includes many tropical trees, some of which are used for timber or have ecological importance and some others of which have fruits and flowers are used as vegetables. Synonyms Caesalpiniaceae R. Brown Cassiaceae Vest Ceratoniaceae Link + Taxonomy Polhill & Vidal (1981) divided the Caesalpinieae into 8 informal generic groups: the Gleditsia group (2 genera), the Acrocarpus group (monogeneric), the Sclerolobium group (3 genera), the Peltophorum group (13 genera), the Caesalpinia group (16 genera), the Poeppigia and Pterogyne groups (both monogeneric) and the Dimorphandra group (10 genera). Polhill (1994) added a ninth informal group, the monogeneric Orphanodendron group, and placed Cordeauxia as a synonym of Stuhlmannia (both genera recognised in the present treatment) so that the total of 47 genera in the tribe remained unchanged. Nowaday, the tribe consists of 56 genera and about 412 - 444 species.
2.2- Tribe Cassieae + Overview ThetribeCassieaeis one of the subdivisions of the plantfamilyFabaceae(the family which includes thelegumes). This tribe includes many tropical trees, some of which are used for timber or have ecological importance. + Taxonomy Tribe Cassieae has 4 subtribes with 21 genera 1- Subtribe Dialiinae (with 16 genera) 2- Subtribe Cassiinae (with 3 genera) 3- Subtribe Ceratoniinae (with 1 genus) 4- Subtribe Duparquetiinae (with 1 genus).
2.3- Tribe Cercideae + Overview Cercideaeis atribein the pea family,Fabaceae. Well-known members includeCercis(redbuds), including species widely cultivated as ornamental trees in the United States and Europe,Bauhinia, widely cultivated as an ornamental tree in tropical Asia, andTylosema esculentum(Maramba bean), a traditional food crop in Africa. The tribe occupies a basal position within the Fabaceaeand is supported asmonophyleticin many molecular phylogenies. At the recent 6th International Legume Conference, the Legume Phylogeny Working Group proposed elevating Cercidae to the level of subfamily within the Leguminosae (Fabaceae). The consensus agreed to the change, but it has not officially been implemented, yet. Synonyms Bauhiniaceae Martynov + Taxonomy †Bauhcis Subtribe Bauhiniinae BarklyaF. Muell. BauhiniaL.
