See text Wisterieae is a tribe of flowering plants in the bean family Fabaceae.

Members of the tribe Wisterieae are either woody lianas or sprawling climbing shrubs.

In particular, unlike the rest of the broadly defined Millettieae, the Callerya group belonged to the Inverted repeat-lacking clade.

[3] A 2019 molecular phylogenetic resulted in most of the Callerya group being placed in an expanded tribe Wisterieae, which included six newly created genera.

The study suggested that the genera included in the tribe could be divided into five major clades, A to E, which were related as shown in the following cladogram:[2] Sarcodum Endosamara Sigmoidala Nanhaia Wisteriopsis Callerya Serawaia Whitfordiodendron Kanburia Afgekia Padbruggea Austrocallerya Wisteria The monophyly of Wisterieae and its broad division into five clades was supported in a 2021 study, with some small differences in clade C. Serawaia was not included in the study, and Callerya bonatiana fell outside the genus Callerya when nuclear ribosomal DNA was used, and was placed in a new genus Villosocallerya.
