Sonneratia caseolaris, also known as the Mangrove Apple or Kirala in Sinhalees, is a species of mangrove tree that is found in the coastal regions of Southeast Asia, including Sri Lanka, India, and Southeast Asia. It is a small to medium-sized tree, typically growing up to 10-15 meters (33-49 feet) tall, with a trunk diameter of up to 30 centimetres (12 inches).

The Kirala tree is known for its characteristic pneumatophores, which are specialized roots that protrude from the soil and help the tree to obtain oxygen in the often waterlogged soil of the mangrove ecosystem. The tree also produces edible fruit, which is used in traditional medicine to treat various ailments.

While the Kirala Tree is an important component of the mangrove ecosystem, it is threatened by human activities such as deforestation, pollution, and climate change. Conservation efforts are necessary to protect this species and the vital ecosystem services it provides, including carbon sequestration, erosion control, and habitat for wildlife.
