More tolerant of sandy and firmer ground than other Rhizophoras, R.
mucronata grows well in soft mud too and is believed to be among the
few that can survive complete daily inundation.
This species of Rhizophora is the most widespread. Their Malay
name refers to their fruit, kurap means "warty".
Main features: Grows 15-25m tall.
Roots: Stilt roots emerging in arches from the lower trunk, and prop
roots may grow downwards from branches.
Leaves: Leaf stipule yellowish. Tiny black spots on the underside
of the leaf.
Flowers: Flower inflorescence long, slender and yellow. Short style
Fruits: Brown, leathery, oval/conical fruit. The seed germinates in
the fruit forming a seedling up to 60cm long. The seedling grows
straight, has a warty bumpy surface and a pointed tip.
Similar trees: R. apiculata: flower inflorescence short, stout, dark
grey. Seedling is shorter (30cm), smooth skin.
Traditional medicinal uses: It is used as an astringent and to treat
angina, haemorrhaging (extracts from the seedlings in Indochina);
diarrhoea (China, Japan): diabetes, dysentery, hematuria. A poultice
of the leaves are used to relief armoured fish stings. Old leaves
and roots are used during childbirth (Malay). Bark is used to treat
