» Introduction to the Ferns
   The ferns are an ancient lineage of plants, dating back to at least the Devonian. They include three living groups - Marattiales, Ophioglossales, and leptosporangiate ferns - as well as a couple of extinct groups.

» Leptosporangiate Ferns
   Next to the flowering plants, the leptosporangiate ferns are the most diverse group of living land plants. Estimates place their diversity at about 12,000 species in around 300 genera. This page is part of the tree of life phylogeny project.
