[plt-scheme] Tree structure in Scheme

If I want to implement a tree-type hierarchy, what is the
data structure? I would like to know who the parent is who the 
children are, so walking up and down, and I also would like
to access
to the leaves directly, not always through the root.

I am looking for suggestions or a documentation or a
discussion about it.
