Difference between Eusporangiate and Leptosporangiate Sporangium

On the basis of development the sporangia have been classified by Goebel into two categories: eusporangiate and leptosporangiate.
Eusporangiate Sporangium: A large sporangium developing from several initial cells producing many spores. There are sometimes fused to form synangia.

Leptosporangiate Sporangium: Small, specialized sporangia developing from a single initial cell producing a small, definite number(<128) of spores. These often occur in a cluster (sorus) that is often covered by a flap of tissue known as an indusium.
Eusporangiate vs Leptosporangiate 
Eusporangiate Sporangium:
Eusporangiate Sporangium


1. A superficial cell divides by a periclinal wall forming an outer and inner daughter cell.

2. The sporogenous tissue is derived from inner daughter cell.

3. The adjacent cells are involved in the formation of the sporangium wall and the stalk.

4. The sporangium is large and massive; the wall is several cells thick and the spore content is high.

5. Primitive.

6.This type of sporangium is seen Psilotum, Lycopodium, Selaginella, Equisetum, Ophioglossum.


Leptosporangiate Sporangium:
Leptosporangiate Sporangium
1. A superficial cell divides by a periclinal wall forming an outer and inner daughter cell.

2.The sporogenous tissue is derived from the outer daughter cell.

3. The sporangium wall and the stalk, as well as the spores are derived from the outer cell.

4. The sporangium is small, the wall is only one cell thick and the spore content is low.

5. Advanced.

6. This type of sporangium is seen Marsila, Azolla, Fern, Salvinia.
