Our knowledge of the organs of rcproductioii is Imrdlj" sufficient 

 to enable us to diagnose the flowers or seeds. No well-marked 

 veins can be detected on the leaves, but the surface is finely

 Several imperfectly preserved leaves converging towards a sup-

represented in the figure of the Fossil Flora are not present in 

 the specimen, but no doubt the uplifted pieces of the lamina have 

 become detached from the surface of the shale since the originrd 

 drawing was made. 



V. 3684. Text-fig. 50. This is one of the few specimens whicli 

 shows any trace of the short axis and the scale-leaves ; the .short 

 leaf bent downwards close to the axis may be a detached scale-leaf, 

 as figured in similar specimens by Heer.
