Tho principal forms of tho apex are the imcrgnaifi (Fig. 122), when the leaf m tipped with a sharp Fig. 124. point, as though the midrib were projecting beyond the blade ; cusjndatef when tho leaf ends abruptly in a very short, but distinctly tapering, point (Fig. 12G); acute, or sharp; and obtuse, or blunt Fig. 125. / 111. It may happen that the apex does not end in a point of any kind. If it looks as though the end had been cut off square, it is truncate. If the end is slightly notcheil, but not sufficiently so to warrant the description obcordate, it is emartjinate. Fig. 128. "^112. Margin. If tho margin is not indented in any way, it is said to be entire. If it has sharp teeth, jxyint- ing in the direction of the apex, it is serrate, and will be coarsely or finely serrate, according to the size of the.
