Eusporangiate vs Leptosporangiate Ferns

On the basis of sporangial development Goebel (1881) classified into two groups,
1. Eusporangiate  2. Leptosporangiate
1. Eusporangiate: large sporangium develops from many initial cells and produces many spores.

Eusporangiate development
In some cases sporangium fuse to form synangium Eg: Psilotum, Selaginella
2. Leptosporangiate: small sporangium develops from single initial cell and produces small definite no. of spores(<128).
Leptosporangiate development
Often in cluster forming sorus and covered by flap of tissue called indusium: Eg: Marselia, Salvinia, Azolla
