. Botany for young people and common schools. How plants grow, a simple introduction to structural botany. With a popular flora, or an arrangement and description of common plants, both wild and cultivated. Botany. GO HOW PLANTS ARE PROPAGATED. o\ 173. The flower-stalk or footstalk of a blossom is called a Peduncle (9G). So the flowers in Fig. 138, 139, &c. arc peduncled or stalked. But in Fig. 1-41 they are sitting on the stem, or sessile. 174. In clusters we need to distinguish two kinds of flower-stalks; namely, the stalk of the whole cluster, if there be any, and the stalk of each blossom. In such cases we call the stalk of the cluster the Peduncle, and the stalk of the individual flowers we name the Pedi- cel. In the Lily of the Valley (Fig. 3, as in Fig. 140), there is the peduncle or general flower-stalk (which is here a continuation of the main stem), and then the flowers all Ivdve pedicels of their own. 175. Kinds of Flower-Clusters, Of those which bear their flowers on the sides of a main stalk, in the axils of leaves or bracts, the prin- cipal kinds are the Raceme, the Corymb, the Umbel, the Head, and the Spike with its varieties; also the Panicle. In the head and the spike the flowers are sessile. In the others they have pedicels or footstalks of their own. 170. A Raceaie is a cluster with the blossoms arranged along the sides of a main flower-stalk, or its continuation, and all on pedicels of about the same length. A bunch of Currant-blossoms or berries, or the graceful cluster of the Lily of the Valley (Fig. 3, 140) are good illustrations. Fig. 142 shows the plan of the raceme. Notice that a raceme always blossoms from the bottom to the top, in regular order; because the lower buds are of course the Spike. 142 Raceme. 143 Corvmb. 144 Umbel. 177. A Corymb is a flat-topped or convex cluster, hke that of Hawthorn. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability -
