Ovate-lanceolate, when it is too long to be strictly ovate, and gradually tapers to the extremity, resembling an ovate leaf in some respects and a lanceolate one in others. Ob-cordate, heart-shaped, with the small end towards the stem. Ob-ovate, egg-shaped, wTith the small end towards the stem. 91. The edges of leaves are variously formed by irregulari- ties, and receive specific names, of w hich the following are most common. If the edge is uniform, it is said to be entire. Serrate, having teeth like a saw, the points directed toward the apex. (Fig. 64.) Dentate, when the teeth are perpendicular to the edge, with the sides equal. (Fig. 65.) Bidentate, large teeth with small ones on them. Biserrate, with similar application. Fig. 64. Fig. 65. Fig. 66.
