to have fewer veins at their margin are in reality only imperfect specimens, 

 whose apparent margin may only represent a position somewhere between 

 the base and the true margin of the pinnule. This remark is more applicable 

 to specimens found in ironstone nodules, such as occur in South Staffordshire 

 and at Coalbrook Dale. 



Cyclopteris semiflabelliformis, Morris, is half of an ordinary pinnule of 

 Cyclopteris trichomanoides which has been split in two.
