Identification :

Main features :   An evergreen, medium sized, much-branched tree that is capable of reaching 20 m height but most of the individuals found in Maldives are only about 6 to 10 m tall.

 

Root :  It is characterized by the presence of numerous stilt roots, which are looping from branches and trunk bases and provide support to trees; they also function as air-breathing roots.

 

Bark :   Grey or dark grey in colour and sometimes longitudinally fissured. Leaves are simple, opposite in arrangement, narrowly elliptic,apiculate (with abrupt slender tip) and smaller than that of other Rhizophoraspecies.

 

Flowers :  Inflorescence is a two-flowered cyme on short, stout, dark grey peduncle and axillary in position. Calyx is four lobed, greenish yellow inside and reddish green outside.Petals are four in number and white coloured; not hairy.
