In one-celled pistils they frequently grow in a line running along one side of the ovary, as in the pea pod, Fig. 176. The ovule-bearing line is called a placenta; in compound pistils there are commonly as many placentas as there are separate pistils joined to make the compound one. Placentas on the wall of the ovary, like those in Fig. 132 A, are called parietal placentas; those which occur as at B, in the same figur
