Avicennia marina

Family : Acanthaceae

This mangrove can range from a shrub of less than a metre to a large, spreading tree. It is multi-stemmed and has pneumatophores (aerial roots) that grow up through the mud. The Grey Mangrove lives in salt water and is tolerable of tidal inundations.

The leaf shape can vary but are often long and tapered. These are pale green on their top side and pale grey on the under side. These are densely hairy and have salt secreting glands to exude excess salt.

Flowers are often bright orange and appear in small but dense clusters. These are stalkless and have a strong, distinctive smell. Flowers typically appear in the late dry season. Fruit pods are fleshy, green and flattened, germinating on the plant before dropping off. These often wash up in large numbers on beaches.

The Grey Mangrove provides shelter and nesting grounds for migratory birds, fish and crustaceans.

Traditional Owner Values

Manbarra - The Grey Mangrove tree is used to make boomerangs as the wood has a natural bend. It also is used to make spear sticks or woomeras.

Bark from the mangrove tree is used as a repellent, and the leaf is used to heal sores because of the salt content.
