BOTANICAL TERMS EMPLOYED PISTIL, Or Carpel-the central point of the flower which becomes the seed-vessel. Stigma-the top of the pistil. Style-the column of the pistil. Germ-the bottom of the pistil, containing the seed. Stamens-the cases of pollen, supported on stalks. Anther-the case containing pollen. Pollen-the dust of the anthers which makes the germ fertile. Filament the thread-like stems that support the anthers. Corolla-the whole case in which the stamens and pistil are contained, usually the coloured part of the flower. Petal-a single leaf of the corolla. Nectary-the honey-cup in the corolla. Calyx-the green cup enclosing the corolla. Sepal-a single leaf of the calyx. Spathe a sheath like that of a daffodil. Receptacle-the bottom of the calyx, or top of the stem on which the flower grows. Superior corolla-a corolla growing above the germ. Capsule-little purse, the case where the seed is contained. Bract-a leaf growing at the foot of the flower-stalk. Cotyledon-a seed-leaf, which springs up first, then falls off. Alternate leaves-those growing by turns on opposite sides of the stem. Serrate leaves-those notched like a saw. Linear-long narrow ones. Pinnate-winged, such as vine leaves. Cyme-a head of blossom like elder. Umbel-a head like hemlock. Frond-a fern, or sea-weed leaf. Imbricated-scales growing one over the other, as in a fir cone. Fibrous root-one in little branches. Bulb-an underground bulb, such as an onion. Tuber—a fleshy swelling on the root like a potato. All these parts of plants are really only leaves in different forms. |
