If the leaf is divided or com- pounded, the general outline of the leaf and the veins or midribs of the leaflets should be made as already directed, and then the outlines of the leaflets should be drawn, as in e, Fig. 76. All guide lines should, of course, be drawn with a very light touch, and erased after the flowers and leaves have been outlined. 122. With a sharp knife make cross and vertical sections of the ovary, and draw to a scale sufficiently large to show the manner of attachment of the ovules (in c and d, Fig. 74)..
