With a popular flora, or an arrangement and description of common plants, both wild and cultivated. Botany. 8 HOW PLANTS GKOW, â "tig. -St. 16. The Pistils are the bodies in which the seeds are formed. They be- long in the centre of the flower. The Morning-GIory has only one pistil: this is shown, enlarged, in Fig. 8. The Rose and the Buttercup have a great many. A pistil has three parts. At the bottom is the Ovary, which becomes the seed-vessel. This is prolonged upwards into a slender body, called the Style. And this bears a moist, generally somewhat enlarged por- tion, with a, naked roughish surface (not having any skin, like the rest), called the Stigma, Upon this stigma some of the pollen, or powder from the anthers, foils and sticks fast. And this somehow enables the pistils to ripen seeds that will grow. 17. Let us now look at a stamen and a pistil from one of the flowers of a Lily (like those shown on a reduced scale in Figures 1 and 2, on the first page), where all the parts are on a larger scale. Here is a Stamen (Fig. 9), with its stalk or Filament, f, and its Anther, a, discharging its yel- low dust or Pollen. And by its side is the Pistil (Fig. 10), with its Ovary, ov.; and this tapering into a Style, St.; and on the top of this is the Stigma, stig. Kow cut the ovary through, and it will be found to contain young seeds. Fig. 11 shows the ovary of Fig. 10 cut through lengthwise and magnified by a common hand magnifying- glass. Fig. 12 is the lower part of another one, cut in two crosswise. The young seeds, or more correctly the bodies which are to become seeds, are named Ovules. In the Lily these are very numerous. Li the Morning-Glory they are few, only six. 18. These are all the parts of the flower, â all that any flower has. But many flowers have not all these parts. Some have only one flower- cup or one set of blossom-leaves. Lilies appea
