CORMOPHYTA. 



also been generally known by the preoccupied name of Palceopteris, 

 occurs in the Devonian and Carboniferous of both Europe and the 

 United States. According to Mr Kidston, it has stipules on the 

 leaves, and its fructification appears to consist of sporangia devoid 

 of annuli, and closely resembling those of the Marattiacece. The 

 genus Aneimeites, from the Devonian of Canada, has been placed 

 by Sir J. W. Dawson and Mr Kidston in the same family ; which is

also taken to include Triphyllopteris, from the European Carbon- 

 iferous. The latter genus has both fertile and sterile leaves. 



With the important family of the Nenropteridece we return to the 

 consideration of true Filices. In this group the leaves vary from a 

 simple to a tripinnate type ; the leaflets being either long or ovoid, 

 and often narrowed at the base, with the midrib disappearing to- 

 wards the extremity, and the veins equal, and in typical forms rising 

 at an acute angle. The genus Neuropteris (fig. 1 371) is a bipinnate 

 type very common in the Carboniferous, but also extending into the 

 Permian of Europe. The allied Cyclopteris (which is not admitted 

 by Mr Kidston as a distinct genus) extends in Europe from the
