The legume family (Fabaceae) includes trees, shrubs, and herbs that produce pods (legumes) and form nitrogen-fixing root nodules through symbiosis with bacteria. The flowers are typically pea-shaped with five petals. This large family provides food staples, timber, and numerous medicinal species. Phytochemical data for this species are limited at present.
