. The elements of botany for beginners and for schools. Plants. which all likeness to leaves is lost, consisting of slender stalks with a knob at summit, the Stamens; and lastly, in the centre, the rounded body, which becomes a pod, surmounted by five slender or stalk-like bodies. This, all together, is the Pistil. The lower part of it, which is to contain the seeds, is the Ovary; the slender organs surmounting this are Styles; the knob borne on the apex of each style is a Stigma. Going back to the sta- mens, these are of two parts, viz. the stalk, called Filament, and the body it bears, the Anther. Anthers are filled with Pollen, a powdery sub- stance made up of minute grains. 17- The pollen shed from the anthers when they open falls upon or is conveyed to the stigmas ; then the pollen-grains set up a kind of growth (to be discerned only by aid of a good microscope), which penetrates the style : this growth takes the form of a thread more delicate than the finest spider's web, and reaches the bodies which are 1o become seeds (Ovules they are called until this change occurs) ; these, touched by this influence, are in- cited to a new growth within, which becomes an embryo. So, as the ovary ripens into the seed-pod or capsule (Fig. 1, etc.) containing seeds, each seed enclosing a rudimentary new plantlet, the round of this vegetable existence is completed. Fig. 9.
