Melaleuca quinquenervia, commonly known as the broad-leaved paperbark, paper bark tea tree, punk tree or niaouli, is a small- to medium-sized tree of the myrtle family, Myrtaceae. It grows as a spreading tree up to 20 m (70 ft) tall, with its trunk covered by a white, beige and grey thick papery bark. The grey-green leaves are egg-shaped, and cream or white bottlebrush-like flowers appear from late spring to autumn. It was first formally described in 1797 by the Spanish naturalist Antonio José Cavanilles.
Native to New Caledonia, Papua New Guinea and coastal eastern Australia, from Botany Bay in New South Wales northwards into Queensland, M. quinquenervia grows in swamps, on floodplains and near rivers and estuaries, often on silty soil. It has become naturalised in the Everglades in Florida, where it is considered a serious weed by the USDA.
