“And there is one of those pins with a seedbox below, one pistil, that is, but the top of this pistil is divided into five parts.” Well, then, the building plan of the trailing arbutus runs as follows:— 1. Calyx. 2. Corolla. 3. Stamens. 4. Pistil. So far, it seems the same plan as that used by the cherry tree, yet in certain ways this plan really differs from that of the cherry blossom. The calyx of the cherry is not cut into separate leaves, as is that of the arbutus; and its corolla leaves are quite separate, while those of the arbutus are joined in a tube. The cherry blossom has more stamens than the arbutus. Each flower has but one pistil. But the pistil of the arbutus, unlike that of the cherry, is five-lobed. So, although the general plan used by these two flowers is the same, it differs in important details. [Illustration: FIG. 212] Above you see the flower of the marsh marigold (Fig. 212). Its building plan is as follows:— 1. Flower leaves. 2. Stamens. 3. Pistils. This, you remember, is something like the building plan of the easter lily. The lily has a circle of flower leaves in place of calyx and corolla. So has the marsh marigold. But the lily has six flower leaves, one more than the marsh marigold, and only six stamens, while the marsh marigold has so many stamens that it would tire one to count them. And the lily has but one pistil (this is tall and slender), while the marsh marigold has many short, thick ones, which you do not see in the picture. So these two flowers use the same building plan in a general way only. They are quite unlike in important details. The pretty little liverwort and the delicate anemone use the same building plan as the marsh marigold. This is not strange, as all three flowers belong to the same family. The yellow adder’s tongue is another lily. It is built on the usual lily plan:— 1. Six flower leaves. 2. Six stamens. 3. One pistil. The wild ginger (Fig. 213) uses the lily plan, inasmuch as it has no separate calyx and corolla; but otherwise it is quite different. It has no separate flower leaves, but one three-pointed flower cup. It has stamens, and one pistil which branches at its tip. [Illustration: FIG. 213] The next picture (Fig. 214) shows you the seedbox, cut open, of the wild ginger. [Illustration: FIG. 214] To find this flower, your eyes must be brighter than usual. It grows close to the ground, and is usually hidden from sight by the pair of round, woolly leaves shooting up from the underground stem, which tastes like ginger. This thick underground stem is the storehouse whose stock of food makes it possible for the plant to flower and leaf so early in the year. Fig. 215 shows you the pretty wake-robin. This is a lily. But it is unlike the lilies we already know, in that its calyx and corolla are quite distinct, each having three separate leaves. It has six stamens, and one pistil with three branches.
