Rafflesia Arnoldi
The Rafflesia Arnoldi which is known locally as bunga Rafflesia (Rafflesia flower) is one of the plants which are protected by law in Indonesia. It is a really rare and a unique plant. It is usually reddish-brown and lives as a parasite on the Tetra stigma vine, as its host. Its petals grow to 50 cm (1.6 feet) long and 2.5 cm (1 inch) thick. The unique of the Rafflesia is it has no observable root or stem, and no leaves. It is a parasitic plant since it has no chlorophyll and haustorium. Nutrients and water are obtained from host cell. This bizarre flower is pollinated by flies attracted by its scent. The buds take many months to develop. It stays in bloom up to 14 days and can be seen during wet season between August - November. This sensitive parasitic plant grows only once a year in primary undisturbed rainforest.

It is now known as the official symbol of Bengkulu province.

The world's largest flower, called Rafflesia, can have a diameter up to one metre and can weigh up to 10 kilograms. It also smells like rotting flesh. We saw and photographed this specimen in a private garden in Sabah, Borneo, the householder charging people to view it. Rafflesia is a parasitic plant that lacks roots, stems, and leaves.

Rafflesia cantleyi

My latest trek to see the Rafflesia cantleyi in Ulu Geroh gave me an opportunity to photograph the various stages of this beautiful and fascinating flower - from bud to decline. My finger/hand had been placed near to the flower for size comparison. And in case there are some over enthusiastic people out there who may be getting ready to bombard me with their "holier-than-thou" attitudes, at no time did my finger or hand touch the flower.

This is the bud-stage. It takes 9 months to journey from bud to bloom.

A bigger bud.

Almost ready to bloom.

The beautiful flower.

This is what the inside of the Rafflesia looks like.

The bloom starts to wither after 3 - 4 days. This is the sad decline.

R. arnoldii

Rafflesia is a huge speckled five-petaled flower with a diameter up to 106 cm, and weighing up to 10 kg. Rafflesia flower has a small life of 5-7 days. Rafflesias have their stamens and pistils fused together in a central column, producing a corona, or crown, in the shape of a ring. The reddish brown colors of the petals, are sprinkled with white freckles. The smell attracts the carrion flies and then pollination occurs. After 9 months of maturation, Rafflesia plant opens into a cabbage-sized bud. The sexual organs are located beneath the rim of the disk.
