Then the parts are said to be free, or to be inserted on the receptacle. So it is in the Buttercup, Lily, Trillium (Fig. 1G2), Flax, &c. But in many flowers one set of organs grows fast to an- other set, or, as we say, is inserted on it. For instance, we may have the Petals and Stamens inserted on the Calyx, as in the Cherry and all the Eose family. Fig. 193 is a flower of a Cherry, cut through the middle lengthwise, to show the petals and stamens growing on the tube or cup of the calyx. The meaning of it is that all these parts have grown together from their earliest formation. Next we may have the Calyx cohering or grown fast to the Ovary, or at least its cup or lower part grown to the ovary, and forming a part of the thickness of its walls, as in the Currant and Gooseberry, the Apple and Hawthorn. Fig. 194 is a flower of Hawthorn cut through lengthwise to show this. In such cases all other parts of the blossom appear to grow on the ovary. So the ovary is said to be inferior, or, which is the same thing, the calyx (i. e. its lobes or border) and the rest of the blossom, superior. Or else we say "calyx coherent with the ovary" which is best, because it explains the thing. Stamens inserted on the Corolla. The stamens and the corolla generally go to- gether. And when the corolla is of one piece (i. e. monopetalous, 213), the stamens almost always adhere to it within, more or less; that is, are borne or " inserted on the.
