Where seen? This shrub with pretty purple flowers is commonly
seen in many of our open wild places, including coastal areas. It
is sometimes called the Singapore rhododendron although it is not
a rhododendron and is not confined to Singapore.
Features: Shrub 1-2m tall, though
they can grow into small trees if left uncut. Leaves narrow and pointed
at both ends (5-9cm long) with 3-5 longitudinal veins. Stems reddish
and covered with bristly scales. Flowers purplish-pink, large (5-7cm)
and showy, 5-10 growing at the end of a branch. According to Corners,
the flower opens only for one day, opening at about 8am and closing
in the late afternoon, the petals falling off a few days later. Shrubs
with white flowers are sometimes seen, and the Malays consider these
to have magical properties. The petals emerge from a cup-shaped calyx
which remains after the flowers drop off. The fruits are berry-like
and break open irregularly. The seeds stain the mouth when eaten,
and is sweet and slightly astringent. They are eaten by children as
well as birds, squirrels and monkeys.
Status and threats: According
to Burkill, the sour young leaves are eaten with food in Java, while
the leaves and roots are used in traditional treatments of diarrhoea
and dysentery.Powdered leaves may be sprinkled over wounds, roots
used for a mouthwash for toothache. It is even used to treat elephants!
The fruits may also be used to obtain a black dye, while the ashes
of the plant is used to fix dyes.
