To do with plants

Stolons are horizontal stems which grow at the soil surface or below ground, they form new plants at the ends or at the nodes.
Stolons are similar to normal stems except they produce adventitious roots at the nodes and they normally run horizontally to the soil surface, instead of up into the air, they also have long internodes.
Plants with stolons are called stoloniferous.
A stolon is a plant propagation strategy akin to a rhizome.
The complex formed by a mother plant and all its clones connected by or produced by stolons are considered to form a single individual.
Runners are above ground stolons and are produced by many plants, with strawberry being a typical example.
Stolons are different from rhizomes because they do not have the the same reduced leaves that rhizomes have at the nodes but have scale like leafs.
Typically stolons have very long internodes and form new plants at the ends which form a shoot that rises to the soil surface and produces foliage and/or flowers.
While rhizomes most often have short internodes with leaf-scars with thin paper-like leaves and root along the under side of the stem, root formation does not precisely correspond strictly to the nodes but roots can generate from areas around the scar-like nodes too.

In mycology( Study of Fungi ) , a stolon is defined as an occasionally septate hyphae, which connect sporangiophores together. Rootlike structures called rhizoids may appear on the stolon as well, anchoring the hyphae to the substrate.

It is a stolon. Some plants like weeds will send out a branch that when it touches the ground develops its own roots. Thus when the parent plant is eaten or pulled out the stolon can continue living and reproduce more stolons spreading its vegetation outward and dominating the area.
Other stolons, like potatoes help to store food. That pretty much covers what stolons do but technically you don't want to hear about the nodes....

Stolon- above ground shoot which puts down roots to spread a plant. Like a rhizome, sort of, but above ground.
Stollen is a holiday bread.

Stolons are modified stems. The usually travel (grow) parallel to the ground. Carpet grass is a prime example. A potato is not a stolon but a tuber. Its main function is food storage.

stolon observed in potato-(rootless)part of the stem grow geotropically and at their end potatoes are formed-example.it is a underground stem modification.
