No idea.

I cannot speak for others but I do not know that.

dto.

It definitely seems so.

My tip is: bogus name of horticultural origin, perhaps geography-related.
> Finally, do we know why the name was assigned
v.s.
>(i.e. presumably the person who named it though the plant deserved the name).
Or this person wanted to sell a few extra clones to all those who already
grow the old, boring _P.heterophylla_. ;-)
>So is it a reference to a location (Papalo where?)
My tip: Mexico, where _P.heterophylla_ is one of the more widespread and
quite variable species.

It may cost a few cents more than "ordinary" _P.heterophylla_.
Kind regards
