Anchored Tree Stem hangs from exactly one Branch
Branch hangs one or many Anchored Tree Stem
Every Branch has to connect at least one Anchored Tree Stem. In the minimal case (shown) this could be a Trunk Stem that grafts a Grafted Branch leading to a Floating Leaf Stem on the opposite side.

Every Anchored Tree Stem must attach to a Branch at some point. This is either at a right angle to the Branch in which case the stem is hanging or it is in line with the Branch in which case the Branch is grafted from the Anchored Tree Stem.
