72 WHERE TO FIND FERNS. 



later fronds bipinnate, sometimes tripinnate, the pinnae 

 ovate and alternate, and bearing fan-shaped, indented, 

 alternate pinnules. The shape of the pinnules very 

 much resembles that of the lobes of the True Maiden-

 Laurence it grows in abundance. But it is quite 

 possible, we think, that diligent search might lead to 

 this pretty little fern being found somewhere along the 

 south coast of England.
