THE BOOK OF CHOICE FERNS. 



porous material of a hard nature, on which their roots run freely, and from 

 which they derive all the nourishment they require. 



These beautiful and most interesting Ferns are usually propagated by 

 division of the rhizomes — an operation which is safe enough, but which, the 

 plants being comparatively slow growers, is a process requiring a certain 

 amount of patience. 



In the following list, which comprises most of the Filmy Ferns in 

 cultivation, an attempt has been made at dividing them into two sections : 

 those with creeping rhizomes are marked by an asterisk (*), while those 

 without the asterisk are species with indivisible crowns. The strongest- 

 growing kinds are indicated by a dagger ("j").
