EXPLANATION OF PLATE L 



Tylodcndron Cowardii. 



-External view slightly reduced In the upper half some of 

 the lozenge-shaped areas (foliar gaps) show the leaf- 

 trace running up from the lower angle of the gap. 



-External view from the other side. The irregular markings 

 in the thickest portion of the fossil may represent the 

 position of branch scars. Both views show a trans- 

 verse mark where the fossil had been cut in two.
