CREATION BY EVOLUTION

Fig. 8.—A seed-bearing fern (Neuropteris heterophylla), one of the Pteridospermae or Cycadofilices. The leaves resemble those of the royal fern (Osmunda regalis), and some of those shown bear seeds. Note that the unexpanded leaves are circinately coiled, as in modern true ferns. The two lower left-hand figures show fronds with seeds attached. Restoration by Miss Janet Robertson. (After D. H. Scott, Extinct Plants and Problems of Evolution, with the permission of the author and The Macmillan Company, Ltd.).
