Chinense - Aji Brown , Aji Chombo , Aji Dulce etc.
Frutescence - AJI CHUNCHO (PI 260480) , AJI DE RATAN (PI 595907) , AJI GUSANITO (PI 543203) aned others
Pubescens - AJI MONGOL , AJI ROCOTO (PI 355811) , AJI ROCOTO (PI 355812)
It's not a matter of the specific pepper being an Aji , as to what language was used to name it by the people who live wherever it grows or whoever brought it to that country...
In some cases it is seed vendors re naming something for more sales...Or in 1 case named by a cartoon writer - Guatemalan Insanity Pepper.
