Special rare tree !!

The name of this tree is "Ulmus Lamellosa".
There are only 8 of this tree in all of Europe.
It has a very special bark, which looks like a puzzle.
Another special thing about the tree is that when branches touch each other, they grow together. You can see this very well.
The two thick branches from below have grown together in both V shapes and to the left of them you see a small hole where two branches have grown together again.
You can see it in the left photo.
Maybe zoom in a bit. In the top photo you see the bark.
Zoom in and you see the puzzle shape.
I photographed this tree in the botanical garden.
Coincidentally, a guide came by with people and he was telling people that. I heard it and then I saw it too, what she was telling.
I was lucky that I heard that by chance.
Good luck all off you these week.
