Examples of the root-stockare very common. Among them we may mention theblood-root and pepper-root as abundant in the woods ofthe Northern and Middle States, and the quack-grass,|3 26G HOW CEOPS GEOAV. represented in fig. 46, which infests so many farms. Eachnode of the root-stock, being usually supplied with roots,and having latent buds, is ready to become an independ-ent growth the moment it is detached from its parentplant.

Suckers.—The rose, raspberry, and cherry, are examplesof plants which send out subterranean branches, analogousto the root-stock. These coming to the surface, becomeaerial stems, and are then termed suckers. The Tubers of most agricultural plants are fleshy en-largements of the extremities of subterranean eyes are the points where the buds exist, usuallythree together, and where minute scales — rudimentaryleaves—^may be observed. The common potato and arti-choke are instances of tubers. Tubers serve excellentlyfor propagation. Each eye, or bud, may become a newplant. From the quantity of starch, etc., accumulated inthem, they are of great importance as food. The numberof tubers produced
