Styphnolobium is a genus of flowering plants in the pea family, Fabaceae. It includes nine species of small trees and shrubs native to China and to the Americas, from the southern United States to Colombia.[1] It belongs to subfamily Faboideae, and was formerly included within a broader interpretation of the genus Sophora. It was recently assigned to the unranked, monophyletic Cladrastis clade.[2][3][4] They differ from the genus Calia (mescalbeans) in having deciduous leaves and flowers in axillary, not terminal, racemes. The leaves are pinnate, with 9–21 leaflets, and the flowers in pendulous racemes similar to those of the black locust. Necklacepod is a common name for plants in this genus.[5]
