I use the term "aji" to refer to capsicum baccatum, the species commonly
grown in South America. I dunno why they are not more common in North
America. A good thing about them is they will not cross with any of the
other species of peppers -- so if you only grow one variety of baccatums at
a time you can save the seeds and keep the variety pure.
