Leptosporangiate Ferns

The largest group of living ferns.

Sporangia arose from a single epidermal cell and not from a group of cells as in eusporangiate ferns.

Many leptosporangiate ferns have an annulus around the sporangium, which ejects the spores.

They are often considered to be the class Pteridopsida or Polypodiopsida.

Polypodiopsida :
Osmundaceae
Hymenophyllaceae
Gleicheniales - Gleichen Ferns
Schizaeales - Broken Ferns
Salviniales - Multi Spore Ferns
Cyatheales - Tree Ferns
Polypodiales - Main Fern Order
