FOSSIL FLORA OF THE STAFFORDSHIRE COAL FIELDS. 91 



No. 21. The inside of this tree was full of fragments of carbonised wood, bound 

 together into a conglomerate-like rock by the infilling marl. It also contained portions 

 of two branches. 



No. 22. The top portion of this stem was overhanging about 8 inches, in a similar 

 manner to that described as occurring in No. 20. 



No. 25. This specimen had a swelling on the trunk about 6 feet from the bottom, 

 from which a branch may have been removed. 



No. 26. This specimen, owing to several transverse fractures and displacement of the 

 segments, had a curious step-like appearance. On the tree being taken down, branches 

 were found in it showing structure. 



No. 28. The upper 4 feet of this stem was pushed aside and overhung about 8 inches. 

 On the specimen was a projection as if a branch had been broken off from that part. 



No. 33. This stem appeared as if it had been subject to great pressure, for in one 

 place it was not more than 9 inches thick. 



No. 39. Several transverse fractures ran through the uppermost 2 feet of this speci- 

 men, and the segments so formed had been thrust to one side and overhung in layers or 

 segments about 2 inches thick. Woodcut, fig. 2* 



The outer surface of the stems is usually converted into coal, and in no case have 

 they shown the form of their leaf-scars, by which alone the generic nature of the stems 

 could be determined ; we are therefore unable to say whether they belong to Sigillaria 

 or Lepidodendron, or in part to both. The only markings observable on the stems are 

 longitudinal striations.
