100 CLADOPHLEBIS. 
The pinne correspond in character very closely to some of those 
of Heer’s species, Gleichenites Zippei,! Corda, but there is not 
sufficient evidence to warrant a removal from the artificial genus 
Cladophlebis. 
iV. 2198. Pl. VIL Fic, 4. 
Long pinne of fairly uniform breadth. The margins of the 
pinnules are entire, and show no signs of subdivision. Venation 
not very clear, but rather of the Cladophiebis than Pecopteris type. 
Cf. Gleichenia Zippet, Corda, as figured by Heer from the Lower 
Cretaceous of Greenland,’? also Pecopteris Zippet as figured by 
Corda in his account of the Lower Cretaceous Bohemian plants,’
