Aspleniineae is a suborder of ferns in the order Polypodiales. It is equivalent to the clade eupolypods II in earlier systems;[1][2] it is also treated as a single very broadly defined family Aspleniaceae.[3] The suborder generally corresponds with the order Blechnales as described by J. L. Reveal in 1993.[4] Aspleniineae includes some important ferns, including Onoclea sensibilis, the sensitive fern, which grows as a virtual weed throughout much of its temperate North American range, and ferns of the genus Thelypteris, a genus that has shown remarkable speciation. It also includes one of the more common horticultural ferns, Matteuccia struthiopteris, the ostrich fern.
Taxonomy
[edit]In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the group is treated as the suborder Aspleniinae, and divided into 11 families.[1] Alternatively, it may be treated as a single, very broadly circumscribed family Aspleniaceae sensu lato, which is then divided into subfamilies.[3] The relationship between the two approaches is shown in the table below.

Phylogenic relationships
[edit]The following diagram shows a likely phylogenic relationship between the families of Aspleniineae (as eupolypods II), based on Lehtonen (2011),[5] and Rothfels & al. (2012).[6]
