Rhizomes, stolons, root-suckers or culms Rhizomes are elongate, root-like stems which travel some distance from the parent plant below the ground. They may produce new plantlets from their tips or from buds along their length. Stolons are similar, but usually travel above the soil surface (e.g. strawberry runners). Includes adventitious roots along stems and at nodes.

Detached aerial stem parts, bulbils or proliferous flowerheads
