· Botanical name :Aegiceras corniculatum

 

Identification

Main Features: This is a multi-stemmed shrub usually reaching about two to three meters in height.  

Root: Unlike the Grey Mangrove (Avicennia marina ssp.australaisica), which has a thick trunk, it does not have pneumatophores (air breathing roots) sticking out of the mud. 

Leaves: It has alternate rounded leaves. The curved-cylindrical fruit, which give the species its name, can be seen in summer and early autumn.

Fruit: The seeds germinate while still on the parent plant and the plantlets can establish quickly after they fall into the mud below, or are left stranded after being transported elsewhere by currents of water.

Identification

Main Features : Avicennia is an evergreen tree growing up to 6m in height

Root : Dark brown aerial roots (pneumatophores) that reach beyond the high tide mark. These roots, forming an intrinsic network which can be best seen at low tide.

Leaves : The tree has ellipticalleathery leaves that are dark green on the front and grayish underneath, often crusted over with salt crystals.

Flowers : The tiny flowers are orange with hardy, exserted stamens.

Fruits :  appear as green 'nuts'. When ripe, they drop into the water and the tides wash them to new locations. Young mangrove shoots are easily identified throughout the Sinai coastline.
