Avicennia marina: is a member of the Avicenniaceae family and is known as the White or Grey Mangrove.
The White Mangrove is a small, bushy tree that may reach a height eight metres with numerous pneumatophores (specialised roots that supply oxygen to the plant) (see right image).
Flowers appear from January to March, are five millimetres across, yellowish and sweetly scented. The capsules, that follow the flowers, are flattened with two large cotyledons. Seeds germinate on the bush before dropping into the water.
Avicennia marina (as with other mangroves) is important in stabilising marine inlets and estuaries against erosion. Mangroves also provide shelter for juvenile fish.
Avicennia marina is Australia’s most widespread mangrove. The species occurs in the Northern Territory, Queensland, New South Wales, Victoria, South Australia and Western Australia.
Seedlings transplant easily but will only grow in saline conditions.
