An underground stem which gives rise to roots and shoots at the nodes A rhizome is often scaly, i e with very small types of leaves Example plant = Couch grass, Elymus repens, syn Agropyron repens
An underground portion of a stem, producing shoots on top and roots beneath; different from a root in that it has buds, nodes, and scaly leaves; rootstock
A horizontal underground stem, such as found in many ferns, where only the leaves may stick up into the air Sphenophytes spread via rhizomes, but also produce erect stems
Rhizomes are not roots, though they may look like them; they are underground stems Instead of growing down, like roots generally do, rhizomes grow horizontally Roots can grow from the rhizome, as can leaves, flowers, and other stems Quack grass, for examples, spreads quickly using its rhyizomes
A specialized plant stem A subterranean horizontal root-like stem sending out leaves and shoots from its upper surface and roots from its lower surface From the Greek, rhiza (rhiza), "root "
Rhizomes are the horizontal stems from which some plants, such as irises, grow. Rhizomes are found on or just under the surface of the earth. the thick stem of some plants, which lies under the ground and has roots and leaves growing out of it (rhizoma, from , , from rhiza ). Horizontal underground plant stem capable of producing the upward shoot and downward root systems of a new plant. This capability allows vegetative (asexual) propagation and enables plants to survive an annual unfavourable season underground. In some plants (e.g., water lilies, many ferns, and forest herbs), the rhizome is the only stem of the plant. In such cases, only the leaves and flowers are readily visible
Horizontal underground stem Commonly refered to as roots because they are underground they act functionally as stems and the true roots emerge from the rhizome
