Aegiceras corniculatum

Black Mangrove, River Mangrove or Khalsi

Family: Primulaceae

Aegiceras corniculatum grows as a shrub or small tree up to 7 metres high (but typically about 2 m) in NSW, Qld, WA and NT along the coast in tidal areas, and extending into south east Asia.

Its leaves are alternate and obovate, to 10 cm long and 5 cm wide. This helps distinguish it from the Grey Mangrove (Avicennia marina) which often grows alongside it in fresher water, which has opposite leaves. Interestingly, the two species are not related! The leaves are leathery and minutely dotted and hence resistant to insect attack.

Its fragrant, small, white flowers are produced as umbellate clusters of 10 to 30.

The fruit is curved and cylindrical or horn-shaped, light green to pink in colour as it ripens; to 75mm long. The seeds are about 5 cm long. 

In the garden

This plant attracts many moths.
It is a species unlikely to be propagated for gardens as it is found in the tidal zone.
However, attempts could be made from seed if you have a boggy soil. It would need regular watering.


Unknown but likely from seed.
