Variations arising directly from buds, rather than from seeds, are bud-variations, and the most marked of them may be described and named as bud-varieties. We have learned in Chapter V how the horticulturist propagates plants by means of buds: not one of these buds will repro- duce exactly the plant from which it was taken. We have already discovered (17, 119) that no two branches are alike, and every branch springs from a bud. Bud-variation is usually less marked than seed-variation, however; yet now and then one branch on a plant may be so unlike every other branch that the horticulturist selects buds from it and endeavors to propagate it. "Weeping" or pendent branches sometimes appear on upright trees; nectarines sometimes are borne on one or more branches of a peach tree, and.
