dendroi/\ all those so far obtained are, however, quite small, 

 only about 30 mm. in diameter. It is almost certain that 

 the large stems, well known as impressions, had secondary 

 wood. 



The cortex in all sections known to me is very badly 

 preserved ; it seems to consist mainly of a soft tissue of 

 large parenchymatous cells. 



It is bounded externally by a narrow belt, 2 or 3 cells 

 thick, composed of squarish cells, with dark, thick walls 

 (See Fig-. 2 of Plate). 



Appendages. 



All the appendages, except some of those at the top, 

 and presumably also some at the bottom of the cone, are 

 sporophyils. 



Each sporophyll is attached directly to the axis, and 

 its horizontal position projects about 6 — 8 mm. in its 

 natural condition. 



The sporophyll is attached to the cone by a ver)' 

 narrow attachment (See Fig. 3 oi Plate and Text-Jig. i). 



The very small area of this attachment accounts for 

 the rarity of whole cones and the great abundance of 

 detached sporophyils. 



The horizontal portion of the sporophyll soon 

 expands considerably. 



There are really two tangential ridges across the 

 under surface of sporophyll separated by a deep groove ; 

 the outermost of these is very large and receives a loop of 

 the vascular bundle, it also serves to increase the block of 

 tissue in which the ligular pit is excavated (See Text-Jig. 

 I, and Fig. 3 o{ Plate). 



The horizontal portion is composed of a small-celled 

 parenchyma coated by a tissue of harder and more 

 rectangular cells ; a definite epidermal layer seems to
