The lower part consists of a symmetrical pair of elegant 'S' scrolls or volutes curling out sideways and downwards from the base of the leaves. The upper part recalls the thrusting growth of leaves and flowers, while the volutes of the lower part seem to suggest both contributing fertile energies and resulting fruits. It is often present on the necking of the capital of Ionic order columns; however in column capitals of the Corinthian order it takes the shape of a 'fleuron' or flower resting against the abacus (top-most slab) of the capital and springing out from a pair of volutes which, in some versions, give rise to the elaborate volutes and acanthus ornament of the capital.
