THE genus Polypodium is another of those immense groups 

 which require rigid investigation and careful subdivision. The 

 species are universally distributed : generally speaking, they are 

 not remarkable for beauty of appearance, but they are so various 

 in figure and habit that no general observation can be strictly 

 applied to them. 



The common Polypody is one of our best known and most 

 abundant ferns ; it is to be found in almost every hedge. It 

 abounds on stone walls, and on the surface of weather-beaten 

 rocks, quickly succeeding the mosses and lichens which first 

 establish a footing in these situations.
