A genus of plants consisting of trees or shrubs which grow in tropical countries along the muddy beaches of low coasts, where they form impenetrable barriers for long distances. They throw out numerous roots from the lower part of the stem, and also send down long, slender roots from the branches, like the Indian banyan tree. The seeds germinate in the seed vessel, the root growing downward until it fixes itself in the mud. The wood is dark red, hard and durable, and the bark is used for tanning.
