Another perspective of the Rafflesia Kerrii, ie from the side.
This flower is actually three days old after the real bloom. The first day, slowly the petals would open up fully. Second day it will go on with the petals in full extend. now as it goes for the third day it curls down a bit. So it begin to shrink days after day. On the fifth day it starts to rot. Finally it will be seen as a lump of dark rot.
I smelled it, but it was not that terrible. Quite bad if you really put your nose into the opening. But actually this one is not that bad.
There were a few flies flying inside out for pollination purpose.

The red flowers have a diameter of 50-90 cm and smell awfully of rotten meat to attract flies for pollination. The plant is a parasite to the wild grapes of the genus Tetrastigma (T. leucostaphylum, T. papillosum and T. quadrangulum). , but only the flowers are visible. Small buds appear along the trunk and roots of the host, which after 9 months open the giant flowers. After just one week the flower dies. The species seems to be flowering seasonally, as flowers are only reported during the dry season, from January to March, and more rarely till July.

The flower is endangered. Though already naturally rare, tourists trying to get close to the flower for photos easily trample the host plant or young buds. Also the locals collect both buds and flowers both as a delicacy as well as for its claimed medical powers. A concoction of cooked buds or flowers is used as a general tonic, to help for fever or backache or even as a sexual stimulant. However western medicine doesn't recognize any medical power of the flower.

Physical characteristics
The Rafflesia body consists of thread like growths on the tissues of a Tetrastigma vine root, on which it is parasitic. The plant produces no leaves, stems or roots and does not contain chlorophyll. The Rafflesia can be seen only when it is ready to reproduce, when the parasitic growths on the vine form a lump that develop into a structure somewhat resembling a cabbage. This cabbage-like bud bursts through the host’s bark, and after about 9 months will open to reveal the massive 5-petaled flower, with stamens and pistils, which develops into a fruit with seeds. The flowers, which sit directly on the forest floor, are each either male or female (female flowers are particularly rare), can measure more than a meter across and weigh 10 kilograms. Most flowers in the genus give off and smell of rotting flesh, hence its local name of “corpse flower.” This smell attracts flies, which pollinate the plant. The center of the flowers contain numerous spikes whose function are unknown, and it also holds several gallons of nectar. The fruit produced is round and about 15 cm in diameter, with thousands of tiny seeds. (2)

Food and feeding
Rafflesia is totally dependant upon a vine called Tetrastigma, which is related to the grapevine. Lacking roots, leaves and stems, the Rafflesia are parasitic upon their host vines, draining nourishment from them. (4)

The visible part of the Rafflesia’s life cycle happens only when it is ready to reproduce. A tiny bud forms on the outside of the vine’s roots or stem, which develops over a period of about a year to a cabbage-like head that eventually opens to reveal the flower. Inside the flower is a spiked disk, to which either stigma or stamens are attached, depending on the sex of the plant. The odor of the plant attracts flies and beetles into the plant to pollinate it. Pollination in Rafflesia is thought to be a rare occurrence due to several factors. Firstly, the flowers are unisex and for the most part are found only in proximity to same sex plants. In order to have successful reproduction, the insect pollinators have to visit both male and female plants, which not only are frequently not in close proximity to each other, but are also not necessarily mature and open at the same time. To complicate matters is the fact that the flowers last less than a week, leaving a narrow window of opportunity for pollination.
The fruit produced by Rafflesia is round and about 15cm in diameter, filled with smooth flesh and thousands of tiny hard coated seeds. The flesh attracts squirrels and tree shrews which are thought to be the main distributors of the seeds.

Hi Foozi,

Another great view of that Rafflesia Kerrii. I still find it difficult to wrap my mind around it being so large. I don't think that I would wish to smell its "fragrance", however -- especially, right up close! Excellent details and colours. TFS.


hello Foozi

a great close-up photo of this flower superbly focused
with great sharpness and details helped with a wonderful luminosity,

Hello Foozi

A flower??? so there's really strange!
I thought of a mushroom ... where is the chlorophille???

Very nice photo sharing and thank you for this!


Hi Foozi,
That must have been a very rewarding find. What I know about this flower is that you don't see them a lot. You found one in a beautiful condition and captured it with great care. I can imagine you are very proud of this find. Was the smell really that horrible?

Hi Foozi,

The close-up view is showing the details and color of the Rafflesia Kerrii flower. It is clear and sharp. The late morning light is enhancing the colors. Have a nice day.


Bonjour Foozi,
Ta précédente publication sur le même sujet valorisait beaucoup mieux la fleur sous un éclairage un peu moins violent et un meilleur angle de prise de vue permettant d'apprécier la finesse des détails.
A bientôt sur TN pour de nouvelles aventures.
