Circuniscissile (circumscindo, to cut around), when the top of the ovary opens or falls off like a lid, as in Jefierso- uia, Henbane, Plantain. Some fruits, as the Gerania and Um- belliferge, are furnished with a cm-pophore^ that is, a slender col- umn from the receptacle—a/wsZ/brm torus^ prolonged through the axis of the fruit, supporting the carpels.

The morphology of the pericarp is exceedingly diversified; but it will suffice the learner at first to acquaint himself with the leading forms only, such as are indicated in the following synopsis and more definitely described afterward. The following is a synopsis of the principal forms of Pericarps, for the blackboa
