Eusporangiate fern

Index Eusporangiate fern

Eusporangiate ferns are vascular spore plants, whose sporangia arise from several epidermal cells and not from a single cell as in leptosporangiate ferns. [1]

Fern

A fern is a member of a group of vascular plants that reproduce via spores and have neither seeds nor flowers.

Gleicheniales

The ferns of the order Gleicheniales are – like all ferns and the related horsetails – sometimes placed in an infradivision Monilophytes of subdivision Euphyllophytina, allowing for more precise phylogenetic arrangement of the tracheophytes.

Leptosporangiate fern

Leptosporangiate ferns are the largest group of living ferns, including some 11000 species worldwide.

Monophyly

In cladistics, a monophyletic group, or clade, is a group of organisms that consists of all the descendants of a common ancestor.

Ophioglossaceae

Ophioglossaceae, the adder's-tongue family, is a family of ferns (though some studies have instead suggested a closer relationship to angiosperms), currently thought to be most closely related to Psilotaceae, the two together comprising the class Ophioglossidae as the sibling group to the rest of the ferns.
