Is there a term to describe all root nodes in a tree?

Question

The root covers the root, what are the other nodes called together?

Answer 1

Like in the real world: branches and leaves

These are all child nodes (from the root or another node).

Answer 2

In the middle, they are called branches. At the very end, they are leaves.

Answer 3

R / \ BL / \ LB / L 

R - root, B - branches L - leaves

Answer 4

I had the same problem: I was creating a base class for all nodes without root and was looking for a short name. Here is what I came up with (and I understand that none of them are perfect):

• NonRootNode is a bit clumsy, but certainly descriptive
• ChildNode - short but potentially misleading
• ParentedNode - I Like This
• NestedNode - may work depending on context
