Family Polypodiaceae

Family Polypodiaceae

Most of the plants we recognise as ferns belong to the large Polypodiaceae family. There are more than 170 genera with over 7000 species. Because differences between genera are not very great, there are arguments as to how some species are related. The type of spore case is one of the main features used to decide where a species belongs. Spore cases in this family are long-stalked with a way of splitting open that is characteristic of the group. MORE! [CH] {FG}
