Description. " Foliolis elongato-lineali-lanceolatis, centim. 6 circiter 

 longis, infra medium millim. 5 latis, basim versus margine inferiore 

 subitius angustatis quam superiore, decurrentibus, sat approximatis et 

 erecto-patentibus." Schimper, 1870. 



This species has a very wide range, both geological and geographical. 

 It is common in the Jurassic of high latitudes in Eussia (the type 

 region), Siberia, Bornholm, and Spitzbergen. In the Lower and Upper 

 Cretaceous indistinguishable remains are rather widely distributed. 

 These occur in the Patapsco formation of the Potomac Eiver Valley, the 

 Earitan formation of New Jersey, the Black Creek formation of North 

 and South Carolina and the Dakota group of Kansas. Whether or not 

 they were specifically identical with the Jurassic forms cannot be proven,
