Leaf Margins

The margin is the edge of the leaf lamina lying between the apex and base. Entire margins are smooth, without indentations or incisions. Revolute margins are rolled downward, toward the lower surface of the leaf. Involute margins are rolled upward, or toward the upper surface of the leaf. Repand margins are slightly and irregularly wavy, with the lamina surface undulating in a downward and upward direction. Sinuate leaf margins are shallowly indented and strongly wavy in the horizontal plane.
