I04 LEAF-ARCHITECTURE OF FERNS [CH. v 



gives its special interest to the comparative study of the leaves of the Ferns, 

 and of the allied Pteridosperms. In fact these most prominent members of 

 their vegetative system provide external characters of greater value for 

 phyletic seriation than are as a rule yielded by the leaves of Vascular Plants 

 higher in the scale. Furthermore, their leaf-architecture serves to illuminate 

 that of Flowering Plants, which we may well believe to have sprung from 

 some Fern-like, or Pteridosperm ancestry.
