112 DR ROBERT KIDSTON ON THE 



Remarks. — A polymorphic species, of which the seed is very similar in size and 

 external characters to that of Neuropteris heterophylla Brongt. It would, in fact, be 

 very difficult, if even possible, to allocate to their respective species the seeds of these 

 two Pteridosperms, if separated from branches bearing their distinctive foliage. 

 Both the obliqua and impar form of the plant occur in this coal field.
