A "How to typedef..." Question

How does one create a type, using typedef, that is defined to be a
pointer to a pointer to a pointer... ad infinitum? The straight-forward
approach is:
typedef tree *tree[2]; /* binary tree, for example */
Which is, of course, grossly illegal. What I would like to be able to
do is write lines such as:
tree t;
t[0] = malloc(sizeof(tree));
t[0][1] = malloc(sizeof(tree));
.
.
.
The closest I have been able to do is:
typedef struct _tree {
struct _tree *t;
} tree[2];
tree t;
t[0].t = malloc(sizeof(tree));
t[0].t[1].t = malloc(sizeof(tree));
.
.
.
Which is *not* what I am after. Just to pique interest, I add that
PASCAL (blech) *allows* this construct. How can this be done in C?
Thanks,
Rick

can't see any reason for wanting to do this. If you don't have an
answer then keep your (computer) shut!
