The tribe Brongniartieae is one of the subdivisions of the plant family Fabaceae, primarily found in tropical regions of the Americas and in Australia[9] The members of this tribe consistently form a monophyletic clade in molecular phylogenetic analyses.

[7][10][11][12][13][14][15][16][17][18] The tribe does not currently have a node-based definition, but morphological synapomorphies have been identified: "stamens united by filaments in an adaxially open tube; anthers alternately long and basifixed, short and versatile; anther connective inconspicuous; septa present between seeds in pods; aril lateral lobe present and fitting into heel of funicle; fine red glandular processes present in axils; and pollen tricolporate with opercula and no definite endoaperture.
