age, and were so described/ Nathorst has considered them as of Upper 



Jurassic age. In his geology of Spitzbergen '^ the possibility of this flora 



being of Neocomian age is pointed out, but in a still later publication ° 



he states that the paleobotanical and paleozoological lines of evidence are 



finally in harmony in regarding the beds as Upper Jurassic, his original 



opinion.'' This flora probably lived so near the end of the Jurassic, if, 



indeed, it may be called a Jurassic flora, as to come within the elastic 



term Wealden; in fact, Seward ' recognized its Wealden affinities in 1895. 



Combining the flora from Cape Staratschin, as revised by Nathorst, 



with that discovered at Advent Bay by DeGeer in 1882, as elaborated by 



the same author, yields the following list:
