. 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. 66 HOW PLANTS AKE corolla-leaves, and the inner corolla-leaves change gradually into stamens, â show- ing: that even stamens answer to leaves. 198\ How a stamen answers to a leaf, according: to the botanist's idea, Fi"-. â 'CD ' O 158 is intended to show. The filament or stalk of the stamen answers to the footstalk of a leaf; and the anther answers to the blade. The lower part of the figure represents a short filament, bearing an anther which has its upper half cut aw^ay; and the summit of a leaf is placed above it. Fig. 159 is the whole stamen of a Lily- put beside it for comparison. If the "whole anther corre- sponds with the blade of a leaf, then its two cells, or halves, answer to the halves of the blade, one on each side of the midrib; the continuation of the filament, which con- nects the two cells (called the connective), answ^ers to the midrib ; and the anther generally opens along w^hat answer to the margins of a leaf 199. It is easy to see how a simple pistil answers to a leaf A simple pistil, like one of those of the Stonecrop (Fig. 154, 15G) is regarded by the botanist as if it were made by the folding up inwards of the blade of a leaf, (that is, of what would have been a leaf on any branch of the common kind,) so that the margins come together and join, making a hollow^ closed bag, which is the ovary; a tapering summit forms the style, and some part of the margins of the leaf in this, destitute of skin, becomes the stig- ma. To understand this better, compare Fig. 160, represent- ing a leaf rolled up in this Avay, with Fig. 156, and with Fig. 161, which are pistils, cut in two, that the interior of the ovary may be seen. It is here plain that the ovules or seeds are at- tached to what answ^ers to the united margins of
