Doesn't DNA analysis sort these things out definitively these days? Or
is it too complicated even for that?

It would be wonderful to use DNA string analysis but it's not so easy
as DNA strings are more complicated to than the plants!

That's not actually the problem. Firstly, it is expensive. But
the real issue is that getting reliable answers from it needs a
rigorous approach to analysis, and most modern taxonomy is a
discipline that is more akin to that of Miss Whiplash than the
statistics I was taught.
