CHAPTER VIII. OP PROPAGATION BY EYES AND KNAURS. The power of propagating plants by any other means thanthat of seeds depends entirely upon the presence of leaf-buds(Fig. XXXIV.), or, as they are technically called, eyes, whichare in reality rudimentary branches ia organic connection withthe stem. All stems are furnished with such buds, which,although held together by a common system, have a power of. Fig. XXXIV. independent existence under fitting circumstances; and, whencalled into growth, uniformly produce new parts, of exactly thesame nature, with respect to each other, as that from whichthey originally sprang. Under ordinary circumstances, an eye remains fixed uponthe stem that generates it. There it grows, sending woody 264 PROPAGATION BY EYES. matter downwards over the alburnum, and a new branchupwards, clothed with leaves, and perhaps flowers; but itoccasionally happens that eyes separate spontaneously fromtheir mother stem, and when they fall upon the ground theyemit roots and become new plants (p. 44, Fig. X.). Thishappens in several kinds of LUy, and in other genera. Man has taken advantage of this property, and discoveredthat the eyes of many plants, if separated artificially from thestem and placed in earth, will, under favourable circumsta
