Aegiceras corniculatum, commonly known as black mangrove, river mangrove, goat's horn mangrove, or khalsi, is a species of shrub or tree mangrove in the primrose family, Primulaceae, with a distribution in coastal and estuarine areas ranging from India through South East Asia to southern China, New Guinea and Australia.

[3] Aegiceras corniculatum grows as a shrub or small tree up to 7 metres (23 ft) high, though often considerably less.

The fruit is curved and cylindrical or horn-shaped, light green to pink in colour and 20–75 millimetres (0.79–2.95 in) long.

[3] It grows in mud in estuaries and tidal creeks, often at the seaward edge of the mangrove zone.

[2] Aegiceras corniculatum extract has analgesic properties[5] which supports a fight against diabetes.
