The history of this plants nomenclature is very interesting. During the
years of discovery when it was far more difficult to distribute
findings, information and meet to assign new names, multiple names were
assigned. The return to historic records, genetic tests can show a very
different picture of who was first or which assigned name is in standing
with the conventions of the time.

It does appear that Fallopia japonica is being proposed as the "new"
right name which should emerge should group consensus agree.

Scientific names change! Its a fact of science!

Simple and clear thing, a scientific name, isn't it?
