I can think of numerous examples of manmade hybrids that are both fertile
and infertile. Are there are any examples of manmade species in the
plant kingdom to serve as precedents?

Since I am unaware of the precedents, it seems to me that this plant
would clearly be a "special case" of hybrid. Being allopolyploid it has
the potential to be a species but it seems that the designation of
species involves more than just genetics. Such factors as habitat,
range, distribution, interspecies variation, pollinators etc. would be

It is still very interesting as a laboratory example of how new species
can come into existence.
