is very common in the softer beds of many coalfields. 

 There is therefore good reason to believe that the 

 specimens which were looked upon by Salter and Binney 

 and others as remains of Monocotyledonous plants are 

 only badly preserved Calamitean casts.

Mr. Kidston^ has already suggested from the evidence 

 of Binney's figure that this plant should be referred to 

 Annularia stellata. At any rate, it is not identical with 

 Lindley and Hutton's Asterophyllites longifolia, as Binney 

 thought, and does not even belong to the same genus, for 

 the free leaf segments are all coherent basally into a 

 sheath. This character forms one important distinction 

 between the genera Annularia and Calamocladus {Astero- 

 phyllites). 



The Ardwick specimens seem to me to agree in all 

 essentials with the definition of this species given by Mr. 

 Seward in his Fossil Plants^ where a full description
