World's Largest Flower Mystery Solved

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."

Damn, super cool.

... 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?

Darn Star Wars...

How many people are going to confuse and/or joke about mitochondria versus midichlorians? Too many. =b

Too see one

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.

Amorphophallus Titanum

What about this monster?

What a name - it means, roughly, "Giant shapeless phallus". Could this describe Darl, too?

Too much of a good thing...

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 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 and Rafflesia as being more like, lets say Lou Reed's Metal Machine Music, played at an extreme volume. (I actually enjoy MMM , 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 olfactory experience as well.
Only the oldest fragrance houses still use these methods. Most companies have replaced the use of animal ingredients with synthetics.

That Smell

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.
