Scars from which leaves have fallen. They usually occur characteristically either singly (alternate) or paired (opposite) or in groups of more than 2 (whorled) at each node. Leaf scars differ greatly in size and shape, and offer some of the best winter characteristics. The points where woody strands of vascular tissue passed up into the leaf are usually evident, and are called bundle scars or bundle traces. Typical leaf scars are essentially at the level of the stem; but they are raised o a pronounced base or leaf cushion in some cases, or the buds are covered by an articular membrane in other.
After a leaf falls, a leaf scar remains on the twig at the point at which the leaf was attached. Within each leaf scar there are one or more bundle scars, each representing a cross-section of vascular bundles that ran from the branch into the petiole when the leaf was attached.
