Which is correct Phrag. dalessandroi or Phrag. besseae var.(f)
dalessandroi.

I have a Phrag. China Dragon made with dalessandroi. If dalessandroi
does not equal besseae then I don't have a China Dragon, do I?

I have seen pictures of them growing together, roots intertwined, on
the same hillside. How could they be different species?
