Pinnularia, L. and H. 

 Pinnularia columnaris, Artis, sp. 



Pinnularia capillacea, L. and H., Fossil Flora, vol. ii. pi. cxi. 

 Hydatica columnaris, Artis, Antedil. Phyt., p. 5, pi. v. 



Middle Coal Measures. 

 Locality. — Fenton, and generally distributed throughout the Coal Measures. 



Remarks. — The plants placed in Pinnularia are evidently roots and rootlets, but it 

 is quite impossible to determine to which plant they belong. Most probably they are 

 the rootlets of many different plants. To the same group of fossils belong the Hydatica 

 prostrata, Artis (loc. cit., pi. i.), and the Myriophyllites gracilis, Artis (loc. cit., pi. xii.), 

 and several other described forms which it seems unnecessary to regard as of specific 

 value, but which would be better regarded as merely roots and rootlets, without any 

 attempt at a specific description.
