FOREST OF WYRE AND TITTERSTONE CLEE HILL COAL FIELDS. 1055 



(vascular) punctiform or transversely lunate, the two lateral oblong, straight or 

 diverging. The ligule pit is situated immediately above the leaf scar, and a short 

 distance above the ligule pit is a transverse furrow, which is sometimes very 

 indistinctly defined. 



The outer surface of the cortex is smooth, or ornamented with very fine irregular 

 longitudinal lines which sometimes are crossed by fine transverse lines. 



Sub-cortical surface longitudinally striated. 



Remarks. — The collection contains only three small fragments of this species, 

 one of which is shown natural size at fig. 3, and enlarged two times at fig. 3a. The 

 leaf scars on this fragment are transversely oval, but only occupy about J of the 

 width of the ribs. The delicate surface ornamentation is seen on the enlargement 

 given at fig. 3a, and consists of short, fine irregular lines, which make an imperfect 

 reticulum. On the same specimen, towards the upper end, where the epidermal 

 layer seems to have been removed, the exposed surface exhibits a fine granulation. 



Another small fragment is given at fig. 2, natural size. Here the upper surface 

 of the cortex is quite smooth and the transverse furrows and ligule pit (above the 

 lower scar) are more clearly seen. Another fragment, enlarged two times at fig. 4, 

 shows the outer surface of the cortex to be also quite smooth. 



The ornamentation is very delicate, and its degree of prominence may be conse- 

 quent on the state of preservation of the specimen, and the granulation sometimes 

 seen may depend on a partial decay of the epidermal surface. 



The var. sparsifolia, as its name indicates, has more distant leaf scars than the 

 type, and they generally occupy a smaller portion of the rib and usually have a 

 greater height in proportion to their breadth, but the variety and the type are 

 connected by intermediate forms.* 



Sigillaria transversalis Brongt. is rare in Britain.
