Well sir, If your friend can get some of these seeds from the earth without having to deal with a dude named Butch Taylor then I will correct the title.
There is also the Naga Viper, bred by a British lad at
http://en.wikipedia.org/wiki/Naga_Viper_pepper . the thing about these peppers is that they were bred and propagated by some skilled growers. The Naga Jalokia was used to fertilize some other super hot strains to make the naga viper. and the aussie lad chose another set of super hots. The Nagag Jalokia on the other hand was found growing wild in india some centuies ago and was a natural evolution and kin o' the earth. So I will keep the title, even if it may be a tad misleading.
the testing used to rate the scoville scale is also very inaccurate. What scientists do will take a known quantity of dried pepper in solvennt (alcohol) say 1ml will be mixed with a quantity of water, in the case of the jalokia it would be 1,001,304 ml is of water. one drop of his solution is dropped on the toung of several scientists until they can no longer feel the effects of capsaicin. this test may only be done once a day per person, and can very significantly with different peppers of the same plant.
