No Natural Order of plants attracts more attention than 
the Ferns, and that attention is attracted by their elegance, 
the freshness of their verdure, the peculiarity of their 
structure, and the ease with which most cf them are cul-

these plants, and to afford him a guide as free as possible

considerations in preparing these pages. 
The engravings, for the most part, will enable any one,

leafy stems ; the under surface of the fronds is traversed
