This sends out some branches under ground, which in the course of the sea- son thicken at the en4 as they receive a stock of nourishment prepared by this year's foliage, and become new tubers (e,a forming one; rf, rf, well-grown tubers of the season), to live over winter and make the next year's growth. 75. Because they live under ground, these tu- bers are commonly sup* posed to be roots; but they are not, as any one may see. Their eyes are buds; and the little scales behind the eyes answer to leaves; while roots bear neither buds nor leaves. The fibrous roots which grow from these subterranean branches are very different in appearance from under-ground stems, as is plain to see in the Potato-plant. Fig. 60 shows a few of the real roots, as well as several branches of the stem, with potato^ form- ing in all stages at their tips. Fig. 61 is one of these form- ing potatoes magnified, show- ing a little scale behind each Boiomna'i-srai. eye which answers to a leaf. Fig. 62 is a part of a slice through an eye, more magnified, to show that the eye is really a bud, covered with little Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Gray, Asa, 1810-1888.
