Type I and Type II superleaves of a tree T with respect to t. Edges in the backbone (defined to be the edges on paths between nodes in the common leaf set) are colored green for shared, red for unique; all other edges are colored black. The deletion of the backbone edges in T defines the superleaves; one is a Type I superleaf because it is attached to a shared (green) edge and the other is a Type II superleaf because it is attached to a unique (red) edge.
