Description

A tree that can grow up to 35m, though usually smaller, around 7-20m, it has a glabrous, smoothish, trunk with reddish brown bark (the bark is sometimes fibrous, sometimes lightish brown or grey). The tree develops short prop-roots rather than long stilt-roots. The green elliptic leaves are 5–15 cm long. Flowers are solitary, with white or cream petals, that soon turn brown up to 1.5 cm long, pinkish-green to reddish brown calyx. The fruit are turbinate (spinning-top shaped), 2 cm long, when mature, the spindle-shaped fruits drop and become embedded in the mud in an upright position, where they rapidly develop roots. The seeds, when still on tree, have a hypocotyl up to 11 cm long.

Habitat

The tree grows on intertidal mud-flats and estuaries, 0-2m (the elevation range between mean sea level and highest tide), on the less exposed parts of the coast, with a rainfall of 1000-8000mm. Common associates on Pacific Island include other mangrove species. The species grows on a wide range of soils, but does best in river estuaries, Salt water habitats on an alluvial sediment allows the tree to spread with its adventitious roots. The black mangrove is a protected tree in South Africa.

Uses

A major use of the tree is for wood products. Its uses in agroforestry include a woodlot, mulch/organic matter production, soil stabilization, coastal protection, windbreak, wildlife/marine food and habitat and bee forage. The wood is widely used, including for firewood, building construction (including structural components such as poles, beams and rafters), canoe parts, fishingstakes, spears, copra-huskers, chips for pulp production, tool handles and digging sticks. In the Andaman Islands the trunks have been used for telephone and transmission poles, it seems rot-resistant (''i.e.'' durable in direct contact with the ground). The wood has a high calorific values, and is used as fuel on some Pacific Islands (e.g. Kosrae), and for charcoal production in Indonesia, and Cambodia. In the Marshall Islands, it has been used for keel-pieces (''maal''), outrigger (''kie''), and outrigger struts (''kein-eon erre''). Paddles are also made from the wood on some islands. The fruit (propagule/hypocotyl) is reported as being eaten after scraping/grating, washing, drying and cooking to remove tannins, and sometimes mixed with coconut in Melanesia and Nauru. The fruit is sold as a vegetable at Honiara Market, Solomon Islands. For the Sowek people, living on

, Indonesia, the fruit is a staple, or primary food, of their diet, due to its high carbohydrate content. The bark is used as an abortifacient and for treating burns in the Solomon Islands. The bark is reportedd to be used for diarrhoea and fever in Indonesia. The astringent (and mildly toxic) bark has also been used to treat malaria in Cambodia. The fruits has antiviral properties, and bark extracts of the closely related '' Bruguiera sexangula'' are reportedly active against at least two types of cancerous tumors (Sarcoma 180 and Lewis lung carcinoma). The bark is used for dying, with colours ranging from red-brown to black (requires repeated dying). For working with leather, the bark has a high tannin content, but tends to colour excessively unless collected "at the end of each growing season". The green propagules/hypocotyl are also eaten by many Indigenous groups in northern Australia. For example, on northwestern
