World's Largest Flower Mystery Solved 32

Posted by timothy from the a-bit-of-it-anyhow dept.
Roland Piquepaille writes "The world's largest flower, called Rafflesia, can have a diameter up to one meter and can weigh up to 10 kilograms. It also smells like rotting flesh. Discovery News tells us that its genetic roots have been uncovered and that this plant that smells so bad is related to delicate flowers such as poinsettias or violets. The researchers analyzed the Rafflesia's mitochondrial DNA (mtDNA), which corresponds to chloroplast DNA. The mtDNA studies revealed that the large, stinky flower is related to more normal-sized, pleasantly fragrant posies, like passionflowers, and other members of the order Malpighiales. This overview contains more details and references. It also includes two photographs revealing the size of the rafflesia when held by a man, as well as details of the flower itself."

    ... now those mocorhorchlorian thingies, are they the 'bad' kind of force, or the 'good' kind of force in this plant?

    I'd go for bad, since its a stinker. Darth Rafflesia, anyone?

    If you would like to see one of these plants there is One in the Winter Gardens, Aberdeen, Scotland. It blooms about once every 9 years.

    The relationship between stinky smells and pleasing ones is an interesting one. Many of the most unpleasant and gut-wrenching odors are not really much more than very intense concentrations of smells that are actually quite pleasant in smaller doses. Or actually, overly-powerful mixtures of several otherwise pleasing odors.

    The smell of soft Ambergris [wikipedia.org] is enough to make most people vomit, and yet it has been a valuable ingredient for perfume (in very small amounts, after being dissolved in alcohol) for centuries.

    Think of other passionflowers as being something like Pachelbel's Canon and gigue in D [uh.edu] and Rafflesia as being more like, lets say Lou Reed's Metal Machine Music [gyrofrog.com], played at an extreme volume. (I actually enjoy MMM [rgreview.com] , though truth be told, only about once a year or so.)

    • By the time Ambegris is ready to be used in perfume, it has been floating around in the ocean for ~10 years. By this time, the odor would certainly not make one vomit and may even be considered pleasant.
      Also, I wanted to mention that some ingredients used in perfumery are not present to provide olfactory enjoyment. For example, civit and castor oils are used as a fixitive in the base of the perfume to preserve the natural floral essences. Ambergris also serves this purpose, but happens to add to the olfacto
    • So. This explains why my socks smell like strawberries when I listen to say, Vivaldis' "Four Seasons". But, smell like a Rafflesia when I listen to say, Joe Satrianis' "Surfing With the Alien"? Just wondering!

    I'd like to know how they found someone to get that close to the thing. You're supposed to be able to smell those flowers from a couple hundred feet away, and even then they can make people with sensitive stomachs retch. The guys who study these things must have either cast-iron stomachs or blown their sinuses out. Or both.

    • Did anyone else see the watermark in the photo [weblogs.com] of the man squatting near the flower and think at first it was like those wafting vapors that cartoons use to show that something stinks?
      Maybe it's just me...
    • I'd guess that most people are blocking their nose somehow. As long as I don't forget to pay attention, I can simply avoid breathing through my nose, ostensibly by flexing some muscle in the roof of my mouth. This won't stop some odor from wafting into my nostrils, but it usually is sufficient to stop me from smelling basically any foul odor from rotting household pet to swamp ass.
    • My guess would be that the prudent scientist would wait until after it finishes blooming and collect the DNA samples then. I can't account for the sinuses of the guy in the picture.
  • Shame these don't grow locally. There are some choice people to whom I would love to send a bouquet.
  • A friend of main claimed it's a meat eating thingy, and that's the reason it smells so bad(to get some flys for dinner)? Is it? Couldn't see anything like that in those links.
    • I don't think so. It's "flowers and bees" thing, except substitue "bees" with "carrion flies"...
    • Flowers that give off the smell of rotten meat or other disgusting things are almost always pollinated by flies, which are attracted to that smell. So there is a very good reason for this smell that, to humans, is repulsive. In nature, there is usually a good reason for most everything.
    • Plants like these are considered carnivous. There are many plants that have similar advantageous, however disgusting, abilities. The venus fly-trap, another carnivorous plant, also produced a similar smell, and has a pink tinge to the inside of it's "mouthes." This effect is used to attract animals that usually eat carrion for sustinence. When the pray is trapped, via the mousetrap-like "mouthes", digestive enzymes are used to break down the potential energy source. Some other examples of carnivorous p
