Where seen? This bush with fleshy green leaves and a 'split'
flower is often seen on our natural shores. Elsewhere, it is found
on beaches and sand dunes, and in mangroves only in sandy, well-drained
areas. It is considered among the most common seashore shrubs in our
part of the world. It has also been introduced to the New World. Previously
known as S. frutescens and S. sericea. It is also called
'Ambong-ambong'.
Features: A shrub that can grow
to a small tree to 3m tall. Leaves thick and succulent (15-25cm long)
hairy on the underside, arranged in a spiral. Flowers (about 2cm)
distinctive with the style curving over the split petals, emerging
in clusters. Petals white, but sometimes with violet stripes. Fruit
small (1-1.5cm) fleshy, green with 1-2 corky seeds, turning white
when ripe. According to Giersen, large bees pollinate the flowers,
although self-pollination also seems to occur. The fruits float in
the sea and may be dispersed by water, as well as by birds. The plant
can form extensive colonies by underground branching of its stems.
Human uses: According to Corners, the leaves are bitter
and "scarcely edible" but the juice of the fruits are soothing
and refreshing for inflamed eyes. The large pith of the young twigs
are sometimes used by Malays to cut into fancy flowers and other objects.
According to Burkill, medicinal uses including the bitter leaves in
indigestion, pith for diarrhoea, poultice of leaves for headaches
and on swollen legs, juice of berries for sore eyes. According to
Wee, in Indonesia the roots are used as an antidote to eating poisonous
fish and crabs. According to Giersen, the wood is resistant to sea
water but found in small quantities so it is used for making nails
for canoes.
