Diplaziopsidaceae is a family of ferns in the order Polypodiales, class Polypodiopsida.[1] They are described as medium-to-large ferns, which grow near streams in forested areas. Their rhizomes are thick and decumbent to erect.[2]

Maarten J. M. Christenhusz and Xuan-Chun Zhang originally described the family in 2011 by including the three genera Diplaziopsis C.Chr, Hemidictyum C.Presl, and Homalosorus Small ex Pic.Serm.[2] But later that year Samuli Lehtonen showed Hemidictyum to be a sister to Aspleniaceae,[3] so they determined that Hemidictyum should be placed in its own family, Hemidictyaceae.[4]

Phylogenic relationships

The following diagram for the eupolypods II, based on Lehtonen, 2011,[3] and Rothfels & al., 2012,[5] shows a likely phylogenic relationship between the Diplaziopsidaceae and the other families of the eupolypods II clade.
