Caesalpinieae Explained

The tribe Caesalpinieae is one of the subdivisions of the plant family Fabaceae: subfamily Caesalpinioideae.^[1]

Genera

Caesalpinieae once included many more genera, but modern molecular phylogenetics indicated that these should be transferred to other clades.^{[2] [3] [4] [5] [6] [7] [8]} Caesalpinieae currently comprises the following genera:^[9]

Phylogenetics

Caesalpinia, as traditionally circumscribed, was paraphyletic, so it was recently recircumscribed to produce many new genera:^[9]
