In 1896 Dr. Hartz,' of Copenhagen, puhlished a description of 

 eighteen species of fossil plants from Cape Stewart on the east 

 coast of Greenland; he considers the flora to be of Rhsetic or 

 Ehaetic-Lias age, hut he expresses his opinion cautiously, and 

 points out that the evidence is hardly sufficient to admit of 

 accurate determination of the geological horizon. Some of Hartz' 

 plants are no doubt identical with Inferior Oolite species.

A few somewhat fragmentary plants have been collected by 

 Nansen ' and by the members of the Jackson - Harmsworth 

 expedition' on the north side of Cape Flora, which suggest 

 a comparison with members of the Inferior Oolite flora of England ; 

 but the specimens are hardly numerous enough and sufficiently 

 weU. preserved to afEord certain evidence of geological age. 



The plants obtained by Nansen were examiued by Nathorst;* 

 and compared by him with the Upper Jurassic flora of Spitzbergen. 

 Among the specimens mentioned by Nathorst the most interesting 

 is a leaf of Ginkgo, very similar to some of the smaller examples
