Avicennia marina, commonly known as grey mangrove or white mangrove, is a species of mangrove tree classified in the plant family Acanthaceae (formerly in the Verbenaceae or Avicenniaceae). As with other mangroves, it occurs in the intertidal zones of estuarine areas. It is distributed along the east coast of Africa, throughout south and south-east Asia, and into Australia. In Australia, it extends much farther south than any other mangrove, occurring in every mainland State. It also occurs in New Zealand between 34 and 38 degrees South.
