The genus formerly had a broader interpretation including many other species now treated in other genera, notably Styphnolobium (pagoda tree genus), which differs in lacking nitrogen fixing bacteria (rhizobia) on the roots, and Dermatophyllum (the mescalbeans). Styphnolobium has galactomannans as seed polysaccharide reserve, in contrast Sophora contains arabinogalactans, and Dermatophyllum amylose.
The New Zealand Sophora species are known as kowhai.[7]
The seeds of species such as Sophora affinis and Sophora chrysophylla are reported to be poisonous.[8]
