The multitude of trees in any ariety, all from one seed, it seems paradoxical to say, are morphologically one individual. A plant variety propagated by buds is essentially complete in its heredity. How, then, can the difference between individual plants in every orchard be explained? Ample explanation is found in "nurture" without invoking a change in "nature." Soil, sunlight, moisture, insects, disease—and, more than any of these, the stock—give every individual plant an.
