Diplazium
''Diplazium'' is a genus of ferns that specifically includes the approximately 400 known species of twinsorus ferns. The Greek root is ''diplazein'' meaning ''double'': the indusia in this genus lie on both sides of the vein. These ferns were earlier considered part of either the Athyriaceae, Dryopteridaceae, Aspleniaceae, or Polypodiaceae families or recognized as belonging to their own taxonomic family. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) places the genus in the Athyriaceae. The taxonomy of the genus is difficult and poorly known, and by 2009 has never been the subject of a complete monographic study. Their distribution is pantropical, with a few species extending into temperate areas. The rhizome of the genus ''Diplazium'' varies from creeping to erect, and is scaly. Its fronds are deciduous or evergreen, are trophopodicThe trophopod is food storage organ described from a number of North American ferns. It consists of the enlarged and modified l ...

Dryopteridaceae
The Dryopteridaceae are a Family (biology), family of leptosporangiate ferns in the Order (biology), order Polypodiales. They are known Common name, colloquially as the wood ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family is placed in the suborder Polypodiineae. Alternatively, it may be treated as the subfamily Dryopteridoideae of a very broadly defined family Polypodiaceae ''Sensu, sensu lato''. The family contains about 1700 species and has a cosmopolitan distribution. Species may be terrestrial plant, terrestrial, epipetric, hemiepiphyte, hemiepiphytic, or epiphytic. Many are Gardening, cultivated as ornamental plants. The largest genera are ''Elaphoglossum'' (600+), ''Polystichum'' (260), ''Dryopteris'' (225), and ''Ctenitis'' (150). These four genera contain about 70% of the species. Dryopteridaceae Evolutionary radiation, diverged from the other families in eupolypods I about 100 million years ago. The fossil record appears to sh ...

Polypodiales
The Order (biology), order Polypodiales encompasses the major lineages of polypod ferns, which comprise more than 80% of today's fern species. They are found in many parts of the world including Tropics, tropical, semitropical and Temperate climate, temperate areas. Description Polypodiales are unique in bearing sporangia with a vertical Annulus (botany), annulus interrupted by the stalk and stomium. These sporangial characters were used by Johann Jakob Bernhardi to define a group of ferns he called the "Cathetogyratae"; the Pteridophyte Phylogeny Group has suggested reviving this name as the informal term cathetogyrates, to replace the ambiguously circumscribed term "polypods" when referring to the Polypodiales. The sporangia are born on stalks 1–3 cells thick and are often long-stalked. (In contrast, the Hymenophyllales have a stalk composed of four rows of cells.) The sporangia do not reach maturity simultaneously. Many groups in the order lack Sorus, indusia, but when presen ...
