Neonotonia wightii

Neonotonia wightii, commonly known as perennial soybean or glycine, is a twining perennial legume native to tropical Africa and Asia, widely cultivated throughout the tropics as a pasture and cover crop legume. It produces clusters of small white to pale purple flowers and trifoliate leaves, growing vigorously in tropical and subtropical climates with moderate rainfall. The species fixes atmospheric nitrogen and is valued for improving soil fertility and providing high-protein forage for livestock.
