Laguncularia racemosa, commonly known as white mangrove or buttonwood, is a species of tree that is found in coastal regions of the United States and South America. The term Laguncularia racemosa is derived from the Latin words laguncula, meaning little water jug, and racemosa, meaning having a raceme or cluster of flowers. Synonyms for this species include Conocarpus racemosa, Combretum racemosum, and Laguncularia ovata. White mangroves are known for their tolerance of salt water and the ability to filter salt out of their leaves. They provide valuable habitat for a variety of marine animals and are important in stabilizing coastal soils.
