Rhizome:

Underground horizontal stem

Usually underground, a rhizome is a horizontal stem of a plant often sending out roots and shoots from its nodes. Rhizomes are sometimes called creeping rootstalks, or rootstocks. Many plants have rhizomes that spread the plant by vegetative reproduction e.g. Lily of the valley.
