    • n rhizome In botany, a stem of root-like appearance, horizontal or oblique in position, lying on the ground or subterranean, bearing scales instead of leaves, and usually producing from its apex a leafy shoot or scape. Rhizomes may be slender, with wellmarked nodes, as in mints, couchgrass, etc., or thickened with stores of nutriment, as in species of iris, Solomon's-seal, etc. - in the latter case producing at the apex an annual bud which furnishes the aërial shoot of the next season, and gradually dying at the old end. Rhizomes shade off gradually into corms and bulbs on the one hand, and into tubers on the other. See these terms. Also rhizoma. See also cuts under arrowroot and moniliform.
