The leaf buds, (Fig. 10,)scales, blossoms, stamens, pistils, fruitand branches are only a developmentfrom one simple structure. The germis converted into roots or stems, or any other organ; hencewe should expect to find the vital points or eyes in all the or-gans, as they are, in fact, the same organ under differentforms, and are easily transformed into each other. We seethese transformations going on around us. In the cultivatedroses, the stamens become petals.
