Excuse my ignorance: Flower tubes?
Never thought on this, but yes I have noticed tails / stingers on things I had not previously noticed. Its more of a back in the day thing. So first thought is there is more variety available today. But you know, I do wonder if maybe some of the newer to the US variety with tails might not be getting mixed into the gene pool by mistake.
Do you have photos? I would love to have jalapeno with a tail. Have been getting more and more interested in lower heat but still cool looking peppers. Jalepeno with a tail / stinger sounds flat cool looking.
