The Group redefined and Tribe Wisterieae (Fabaceae) emended based on morphology and data from nuclear and chloroplast DNA sequences.

The Tribe Wisterieae (Zhu 1994), founded on the single genus , is emended and recircumscribed based on morphology and data from nuclear ITS and , and chloroplast DNA sequences. This newly enlarged tribe comprises 36 species and 9 infraspecific taxa within 13 described genera. Six genera are new, two are reinstated and five were previously placed in Tribe Millettieae. The genus is also reinstated comprising two species including the new combination . Other reinstated genera include , with four species, and , with three species, including the reinstatement of and the new combination P.filipesvar.tomentosa. The existing genera , , (with the new combination E.racemosavar.pallida), and , with the new combinations W.frutescenssubsp.macrostachya are evaluated. The new genera comprise three Australasian species in : , and ; with five species from east Asia has six new combinations: , and W.reticulatavar.stenophylla. Two species comprise the new Thai genus : and . comprises the two species: and and the monotypic genera and are based respectively on the species and . Lectotypes are designated for the names , , , , M.reticulatavar.stenophylla, , , , , and . A neotype is designated for the name .
