features
The shoot axes are creeping to mostly upright. Hair or flakes are missing. The leaves are dimorphic, sterile and fertile parts are different. The leaf blades are comb-shaped (pectinate) to simply pinnate. The nerves are simply bifurcated, they end freely or anastomose in fertile leaf blades at their end. Young leaves are densely covered with multicellular, glandular, mucous hairs.
The Sori have no Indusia . The sporangia are located on the distal areas of the nerves. The sporangia stalks are six rows, the annulus is slightly opaque and continuous. The spores are tetrahedral and trilet (three-part scar).
The gametophyte is green and heart-shaped.
The basic chromosome number is x = 66?

It was first published in 1850 under the name ( Basionym ) Lomaria sect. Plagiogyria Kunze by Gustav Kunze in Die Farrnkräuter , Volume 2, page 61. It received the rank of a genus in 1858 by Georg Heinrich Mettenius in treatises published by the Senckenbergische Naturforschenden Gesellschaft , Volume 2, 1, page 265.
