Each separate piece or leaf of a corolla is called a Petal: and each leaf or piece of a calyx is called a Sepal. 20. The corolla, the stamens, and generally the calyx, fall off or wither away after blossoming; while the ovary of the pistil remains, grows larger, and becomes 21. The Fruit. So that the fruit is the ripened ovary. It may be a berry, a stone-fruit, a nut, a grain, or a pod. The fruit of the Lily and also of the Morning- Glory is a pod. Here is the pod or fruit of the Morning-Glory (Fig. 4, fr. and Fig. 13), with tiie calyx remaining beneath, and the remains of the bottom of the style resting on its summit. And Fig. 14 shows the same pod, fully ripe and dry, and splitting into three pieces that the seeds may fall out. This pod has three cavities (called Cells) in it; and in each cell two pretty large seeds. Lily-pods have three cells, as we may see in the ovary in the flower (Fig. 12), and many seeds in each. 22. Seeds. These are the bodies produced by the ripened pistil, from which new plants may spring. Here (Fig. 15) is a seed of Mornin^-Glory, a little enlarged. Also two seeds cut throuiih lengthwise in two different directions, and viewed with a magnifying-glass, to show what is inside (Fig IG^ 17). The part of the seed that grows is 23. The Embryo, or Germ. This is a little plantlet ready formed in the seed. In the Morning-Glory it is pretty large, and may readily be got out wdiole from a fresh seed, or from a dried one after soaking it well in hot water. In Fig. 16 it is shown whole and flatwise in the seed, where it is a good deal crumpled up to save room. In Fig. 17, merely the thi
