Aspleniineae
Aspleniineae
Suborder of ferns
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.
