This function enumerates all possible homeomorphicallyreduced trees (no degree2 vertices) with a distinguished root and n1 unlabeled leaves. Each tree is an object of class LeafTree. For the purposes of representation, the root is named 0 and the unlabeled leaves are named $1,\ldots,n1$. In other words each class of unlabeled rooted tree is represented once by a particular labeling of that tree.

The object rootedTrees is a method function.
