THE FLOWER. 43 generally composed of spikes or racemes, which are centri- petal in their flowering. 51. The flower is that organ of the plant which is designed for the production of seed, and thereby the continued existence of its kind. In a complete flower, such as the Buttercup, Rose, Phlox, etc., there is externally the calyx (Fig. 96, ea), or cup-like portion, which consists of several parts, either distinct or united, which more or less resemble ordinary foliage leaves (Fig. 96). Each leaf, or portion of the calyx, is called a sepal; within this whorl of leaves forming the calyx is a second whorl, either of distinct or more or less , called the corolla (Fig. 96, cor). This is c(ftnmonly the most showy part of the flower. Its component parts are called petals, and they usually depart farther from the ordinary form and texture of ^^^^0^^Aa foliage leaves than do the sepals. 52. Within the corolla are slender bodies called stamens (Figs. 96,101, etc). They sometimes revert to petals or sepals (Fig. 84), showing that they are also modified leaves. These bodies are sometimes excess- ively numerous; and when few, are rarely less in number than the parts of the corolla or calyx. Within these, and occupying the central part of the flower, are the pistils (Figs. 96, 101, etc.); in the lower enlarged part of which (called the ovary) the seeds are produced. The pistils, like the stamens, may be numerous, but are very often reduced to one or two. It is very common for the pistils to revert to ordinary green foliage leaves. There can be no production of seed without both stamens and pistils, and for this reason Fig. 96. A Flower : m, calyx; cer, corolla; in, Tnon,.
