leaf and should not be referred to a genus implying affinity with 

 a particular class. The other species, C. armata, is probably a 

 piece of a spinous axis like that of the Wealden plant Sewardia 

 latifolia (Sap.). A fragment figured by FHche and Bleicher^ 

 from the Jurassic of Nancy as C. tvberculata is another example 

 of a fossil which cannot be referred with any certainty to the 

 Cycads. 



Dr Stopes^, inadvertently overlooking the previous institution 

 of Cycadorachis, has recently proposed the name Cycadeorachis 

 for pinnately branched rachises of Cycadeanf ronds which, 'while 

 indicating the general character of the frond, do not show the 

 shape of the pinnae well enough to be associated with any of the 

 many foliage-genera.'
