chinense Borbhut landrace - possibly the hottest pepper ever recorded?

well you already brought up the interspecific cross thing.  This paper sites an indian lab but the better citation is:
 
A weird wrench in this theory is some phylogenetic evidence that the indian super-hots split before the frutescens-chinense split. This discovery was published in 2012 and the same group submitted the new species name assamicum that same year.

But a literature analysis found, i think, not enough novel characteristics to define the new species, and the assamicum group lost footing and it didn't catch on.

But! you described the placental tissue displacement. Does not this qualify as a novel characteristic? Could it possibly have evolved separately in both the trinidad and assam peppers? Somebody should find out!
