PLATE III. 



Calamites nodosus. 



LlKDL. AND HUTT. 



The name given is that in the " Fossil Flora." This 

 specimen could with equal authority be referred to 

 Asteropliyllites, or to Schimper's provisional, convenient, 

 but compromising genus Calamocladiis. So far as 

 external characters are concerned (and of these alone 

 we can judge here), it is a Calamarian or Astero- 

 phyllitic stem, with attached Asterophyllitic foliage. It 

 is not the Calamites nodosus of Sternberg, but forms 

 one of that large group of leaf-covered branches which 

 Schimper has brought together under the name Calamo- 

 cladus longifolius. This Plate forms an instructive 

 supplement to the preceding one. 



" The Newcastle coal-field" is the only locality given. 



The original specimen and drawing (by Prior) are 

 twice the size of the Plate.
