    It’s very rare to have a real tree branch merge back into the trunk.

    Not rare, but uncommon. Not sure if there’s a Lemmy equivalent but r/treessuckingonthings shows trunks absorbing all sorts of things including branches

      Yes, this is why I chose not to say that it was impossible.

      Perhaps the mathematical definition of a tree is wrong in stating there should be not loops, or should change to another metaphor.

      Hairs can split but never merges back again. Perhaps a split hair instead of a branch? We still trim or prune the leaves ends. What do you call the “trunk” of a hair?
