Based on these clear definitions, Sachs (1868) described the life cycles of green algae and land plants with reference to the European birthwort (Aristolochia clematitis). Using flowers of this species, he analyzed the processes of pollen growth, fertilization, and the subsequent development of embryos within seeds.
