If they are bumpy/pimpled pods, people like to call them 7 pods even if they aren't. If there is a tail/stinger, people like to call them scorpions even if there is no relation.
Great for marketing/sales, terrible for chile taxonomy
Ive read a couple articles that Bhuts are related to 7 pots. There are many ties between T&T and India from Slavery in the 1800's and it is though 7 pods as we call them where brought back to India. Just what iv'e read and it makes sense.
