PLATE XIX. 



Sphenopteris macilenta. 

 Lindl. and Hutt. Var. 



This fragment seems to approach nearest to this species, 

 which is, however, a rare one in the North of England. 



The locality is Jarrow, and the horizon is the shale 

 above the Bensham seam. 



From the notes which have been preserved it appears 

 that the authors of the u Fossil Flora" intended to attach 

 a new name to this example. 



Natural size, original drawing by Prior.
