Paths don't have leaves. They have beginnings, endings, and middles. They are linear.
This sheds their context. The linear sequence does not exist in a vacuum. It is a sequence of nodes that defines a path through a filesystem tree. When I think of a filesystem, I think of it as (a) root node(s), interior nodes, and leaf nodes. The fact that I'm only looking at a subset of them when dealing with a given path does not change what kind of node each is conceptually.
I think that proves my point. On a Unix system "/usr" is never a leaf in the filesystem. Boost.Filesystem can call it a leaf, though.
In short, I like "leaf()".
