The tribe Indigofereae is a subdivision of the plant family Fabaceae. It is consistently recovered as a monophyletic clade in molecular phylogenies. The Indigofereae arose 30.0 ± 3.3 million years ago (in the Oligocene). This tribe does not currently have a node-based, phylogenetic definition, but it can be distinguished by the following morphological synapomorphies: the presence of biramous hairs, keel spurs, short free staminal filaments, and short fruiting pedicels; and the loss of stipels and seed arils. Indigofereae comprises the following genera: Modern molecular phylogenetics suggest the following relationships:
