196 NORTH STAFFORDSHIRE COAL FOSSILS. 



ironstones. The New ironstone or Rag mine contains 

 beautiful examples of Lepidodendron, Sigillaria, and Cala- 

 mites, many of them showing structure. So far as our 

 investigations have gone, we find that the various genera 

 and species recorded in our list are alike common to the 

 whole of the plant-bearing beds of these coalfields. We 

 know of no particular genus or species which is confined 

 to any special horizon. 



Of the great number of fossil plants which have been 

 recorded from British carboniferous rocks, only a small 

 portion have yet been found in these coalfields. This 

 small number no doubt inadequately represents the total 

 number which a closer examination would supply. 



In drawing up the following list of plants, we beg to 

 acknowledge the assistance rendered by Mr. Garner in 

 affording us the opportunity of examining his collection of 

 fossil plants from this coalfield, now in the Stoke Museum, 

 and also our obligation to Mr. Lunn, for the valuable 

 assistance he has rendered by furnishing a list of the 

 fossil plants in his collection, from the Pottery coalfield.
