Lumnitzera racemosa, commonly known as the white-flowered or gray mangrove, is a species of mangrove tree belonging to the family Combretaceae. It is found in coastal regions of the Indo-Pacific, including countries such as India, Sri Lanka, Bangladesh, Myanmar, Thailand, Malaysia, Indonesia, and Australia. Lumnitzera racemosa is characterized by its grayish bark, oval-shaped leaves, and small white flowers arranged in racemes. It typically grows in the intertidal zones of mangrove forests, where it can tolerate saline conditions and periodic inundation by tides. This mangrove species provides important ecosystem services, such as stabilizing shorelines, filtering sediments, and serving as habitat for various organisms. It also contributes to nutrient cycling and plays a role in carbon sequestration.
