Description	Leaf shapes are very variable but restricted to some stereotyped families. Among one family of lobed leaves, this shape can be related to its folded growth within the bud. In general, this open the question of how much the final shape can be constrained by steric constrains during its development. Similarly, since most of the leaves do not first expand flat and straight, but commonly folded or rolled in different ways, there needs to be some regulations to reach the usually rather flat and straight state. This growth, from the primordial to the final leaf, presents several striking motions. On some examples we propose that these motions precisely help the regulation.
