PLATE II. 



Calamites nodosus. 



SCHLOTH. 



At Plate XV. of the " Fossil Flora" a specimen very 

 similar to the present one is figured. Each lacks 

 something possessed by the other. In the former a 

 branchlet, with attached Asterophyllitic leaf- whorls, is 

 seen apparently in place with regard to the Calamitean 

 stem by its side, but the actual junction, if it ever were 

 there, is not visible. On the other hand, our drawing 

 shows the embranchment very clearly, but the leaf -whorls 

 are missing. 



Referring to their figure the authors of the " Fossil 

 Flora" remark: — " Although we have examined a fine 

 series of specimens of this fossil [Calamites], where the 

 leaf-bearing branch is always associated with the stem, 

 yet, as in no instance they have been found actually in 

 conjunction, Fig. 1, Tab. 15, being the nearest approach 

 to it that we have seen, we pause before we finally 

 decide [that the leaves are really those of Calamites]." 

 (" Fossil Flora," Vol. L, p. 54; see also " Catalogue," 

 p. 9.) 



Hutton, in naming his collection, seems to have had 

 no doubt as to the propriety of referring all the foliaged 

 specimens like the one described above to Calamites 

 nodosus. There is no reason to doubt the specific identity 

 of his and our figured fossils, and the only question open 

 to discussion is the larger one : " Do the stems in question
