4-430: Blechnales Pic.Serm. ex Reveal Aspleniineae is a suborder of ferns in the order Polypodiales . It is equivalent to the clade eupolypods II in earlier systems; it is also treated as a single very broadly defined family Aspleniaceae . The suborder generally corresponds with the order Blechnales as described by J. L. Reveal in 1993. Aspleniineae includes some important ferns, including Onoclea sensibilis ,
8-470: 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. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the group is treated as
12-769: The suborder Aspleniinae, and divided into 11 families. Alternatively, it may be treated as a single, very broadly circumscribed family Aspleniaceae sensu lato , which is then divided into subfamilies. The relationship between the two approaches is shown in the table below. The following diagram shows a likely phylogenic relationship between the families of Aspleniineae (as eupolypods II), based on Lehtonen (2011), and Rothfels & al. (2012).
