This is a rare British plant, somewhat similar in habit to 

 S. obtusiloba Brongn. and S. neuropteroides (Boul.), but differ- 

 ing from both in the pinnules being larger, more contracted at 

 their base, and in the rachis being slenderer and non-striated.

 Middle Coal Measures of Kent.

This species is widely distributed vertically, and is of fairly 

 common occurrence in Britain, although it has been but rarely 

 figured. With the specimen figured here may be closely compared 

 the very nearly allied species 31. splierwpteroides (Lesq.).
