Solanum x aemulans (aemulans means similar and was a reference to S. demissum according to Hawkes) is an Argentinian nothospecies (natural hybrid) with a complex taxonomic history.  It was originally described as a species, then a variety of S. acaule, then a subspecies of S. acaule, back to a variety of S. acaule, and most recently as a naturally occuring hybrid of S. acaule x S. boliviense.  It isn’t clear how this would work.  S. acaule is typically 4x and 2EBN, while S. boliviense is 2x and 2EBN.  From this cross, the prediction would be 3x, 2EBN progeny.  There doesn’t appear to be any way for these species to produce a tetraploid.

Cultivation

I have found this species slow to germinating, taking about twice as long as S. tuberosum under the same conditions.
