At several points along the main stem branches are given off, and you will observe that immediately below the point from which every branch si)rings there is a leaf on the stem. The angle between the leaf and the stem, on the upper side.' is called the auil of the leaf {aA-ilhi, an armpit), and it is a rule to which there are scarcely any exceptions, that branches can only spring from the axils of leaves. The stem and all the branches of our plant termi- Fig. 3 nate, at their upper extremi- ties, either in flowers or in flower-buds. 4. Let us now consider the Leaves. A glance will Bhow you that the leaves of this plant are not all alike. Those at the lower end of the stem have long stalks, (Fig. 4) which we shall henceforward speak of &B2Jetioles, Those a little higher up have petioles too, but they are not.
