STIPOLAIn botany the stipules are two expansions that are found at the base of the petiole of many leaves, arranged symmetrically, at the point where the petiole inserts into the branch.
They can have different shapes, sizes and durations: for example in apple and plum trees, after the unfolding of the leaves, they fall; in the broad bean and pea they are large epersistent and perform the normal chlorophyll function; other times as inSmilax they have the form of tendrils or thorns as in the case of Robinia.
