A RootstOCk is any kind of hoi-izontal stem or branch growing under ground. Slender rootstocks occur in the subterranean part of the suckers of Roses, of Pepper- mint, or of Canada Thistle, and of Quick-Grass or Couch-Grass (Fig. 75), which spreads so widely, and becomes so troublesome to farmers. They are Avell distinguished from roots by the leaves which they bear at every joint, in the form of scales, and by the buds which they produce, one in the axil of each scale. These bud?, which are very tenacious of life, are what renders the plant so exceedingly difficult to destroy. For ploughing and hoeing only cut up the rootstock into pieces, each with a tuft of roots ready formed and with a bud to each joint, all the more. ready to gro" *.>r the division. So that the attempt to destroy Quick-Grass by cut- ting it up by the roots (as these shoots are called), unless the Roouiock uf auick-gratt. picccs arc carefully taken out of the soil, is apt to produce many active plants in place of one. 104. Thickened or fleshy rootstocks, such as tho!!e of Solomon's Seal (Fig. 63) and Iris (Fig. 64), have ah*eady been illustrated (76). 105. A Tuber is a rootstock thickened at the end, as already explained in the Potato and Ground Artichoke (74,75, Fig. 59, 60). The eyes of a tuber are lively biJds, well supplied with nourishment for their growth. 106. A Corm or Solitl Bulb, as of Gladiolus and Crocus (Fig. 76), is a sort of rounded tuber. If well covered with thick scales it would become 107. A Bulb. This is a (mostly subterranean) stem, so short as to be only a flat plate, producing
