Sesbania

Morphological Summary

Genus of herbs, shrubs and trees in the family Fabaceae (subfamily Faboideae), with around 60–70 species distributed in tropical and subtropical regions worldwide. They are fast-growing, nitrogen-fixing plants that colonise riverbanks, wetlands and disturbed areas. Several species are of great agronomic importance as green manures and soil improvers (especially S. sesban and S. bispinosa). S. formosa is the most striking arborescent species, native to Australia, with large white flowers.
