Senna siamea, commonly known as the Kassod Tree or Siamese Senna, is a medium-sized evergreen tree that can grow up to 18 meters tall. It has a dense, rounded crown that becomes spreading and irregular at maturity, with alternate, pinnately compound leaves featuring 6-12 pairs of oblong leaflets. The flowers are bright yellow, appearing in large, terminal panicles, while the fruit is a long, flat pod, dark brown when mature, containing numerous seeds. Native to South and Southeast Asia, including Thailand, Myanmar, Malaysia, India, Sri Lanka, and Bangladesh, the tree has been widely cultivated and naturalized in many tropical and subtropical regions around the world.
The Kassod Tree’s ecological significance extends beyond its physical characteristics, as it provides a valuable food source for various wildlife species, including birds and small mammals.
