Terrestrial or epilithic ferns. Rhizome creeping or suberect to erect. Fronds monomorphic, approximate or tufted. Stipe and rhachis adaxially grooved, stipe with 2 strap-shaped vascular bundles merging upward into a single U- or V-shaped bundle. Lamina pinnately compound, basiscopically developed or not; veins free or anastomosing. Sori superficial, circular to elongate, linear or J-shaped, borne on the veins, with or without an indusium, homosporus.

Woodsiaceae

provided by wikipedia EN

Woodsia is a genus of ferns in the order Polypodiales. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is the only genus in the family Woodsiaceae, placed in the suborder Aspleniineae.[1] The family can also be treated as the subfamily Woodsioideae of a very broadly defined family Aspleniaceae sensu lato.[3] Species of Woodsia are commonly known as cliff ferns.[4]

Taxonomy

Woodsiaceae formerly included the members of the families Athyriaceae and Diplaziopsidaceae, but analysis has consistently shown that they should be treated as separate families.[5] The following cladogram for the suborder Aspleniineae (as eupolypods II), based on Lehtonen (2011),[6] and Rothfels & al. (2012),[7] shows a likely phylogenetic relationship between the Woodsiaceae and the other families of the Aspleniineae.
