The natalensis story is even stranger: the underground was growing what they thought was natalensis for many years, until someone finally did the sequencing and found out that what everyone had grown and loved was actually new to science. At this point last year, their "natalensis" received its proper scientific name, ochraceocentrata. The underground then had to go out and fetch some actual natalensis, which is only just now being introduced to those circles (eg by Yoshi Amano). I haven't yet tried true natalensis, but ochras are definitely distinguishable from the usual cubensis, experentially, and I'd heartily recommend them to anyone that likes that kind of thing.
