runner

or

stolon

a long, slender stem running along the surface of the ground, arising from the axil of a leaf, whose function is to enable rapid VEGATIVE PROPAGATION in an area. Along the runner are small scale-leaves with buds from which roots emerge and enter the soil. Eventually the runner withers, leaving many new daughter plants (each is a CLONE). Runners are found in, for example, strawberries and creeping buttercup.
