Genus CYCADITES, Sternberg. 

 [Flor. Vorwelt, iv. p. xxxii. 1825.] 



Sternberg proposed this name in 1825 for three fossil plants 

 from the Lower Cretaceous of Hor in Scania, and one from Radnitz 

 in Bohemia. He denned the genus as follows : " Folia pinnati- 

 fida seu pinnata, nervis validis sirnplicibus e rhachi horizontaliter 

 exeuntibus." 



Sternberg's species Cycadites Nihsoni had been previously 

 figured by Nilsson in 1820, 1 but he left the plant unnamed; 

 this species is now included in the genus Nilssonia. Another 

 of Sternberg's species, C. linearis, is no doubt, as Presl first 

 suggested, 2 a fragment of some fossil stem. Cycadites palmatus, 

 Sternb., from Radnitz, is probably a fragment of Cordaites, and 

 C. zami&foliw suggests a coniferous twig. In 1824 Nilsson 3 

 figured a portion of a leaf from the Quadersandstein of Hor, with
