I have been able to trace the stages of development in two species, of 
which .S. rupestris appears to be less specialized than 5 . digitata . The 
Fig. 3. i-iv. Successive transverse sections from the axis of a young plant of Anemia phylli-

material of 5 . rupestris was collected in Australia, chiefly in the district of 
Wentworth Falls, in the Blue Mountains. It was found growing on rocky 
ledges, sometimes actually under the spray of waterfalls. The vegetative
