As to the age of the plant-bearing deposits as a whole, there 

 can be no doubt that this must be lower carboniferous. For such 

 an opinion the occurrence of Calymmatotheca bifida and Lepido- 

 dendron spetsbergense as w^ell as that of Asterocalamites scrobiculatus 

 may be cited; and none of the other plants speak in an opposite 

 direction. This is all that can be said at present, the materials 

 being too scanty to allow of any more detailed conclusions. Owdng 

 to the great thickness of the plant-bearing beds it is probable that 

 a more minute examination, from a stratigraphical point of view, 

 will prove that several plant-bearing horizons may be distinguished.
