This provisional genus was established by Saporta and Schimper to include a number of ferns mostly Jarassic, and characterized by being pinnate with spreading pinuic, the pinnules attached by the whole base, the apex pointed or obtuse, sometimes dentate, especially toward the apex, which is often turned upward, giving a falcate Ibrm. The midrib is strong but fading away into nerves toward the apex. Nerves at acute angles with the midrib, usually forking once or twice. The well known Peeopteris Whit- Trans.
