10 NATHORST. FOSSIL PLANTS OF FRANZ JOSEF LAND. [norw. pol. exp. 



CYCADALES. 



PTENOPHYLLUM, Brongniart. 



PteropJiyllum? sp. 



PI. I. figs 7 and (magnified) 57. 



Tfie only specimen that witli any certainty belongs to the Cycadales is 

 the Httle fragment in question. It is a pinna of a frond, probably regularly 

 divided, the pinnae of which in their entire breadth have been attached to 

 the rachis. They are rounded at the apex, and, when enlarged, four un- 

 branched veins are visible in the pinna represented. 



This is no true Pterophyllum, though provisionally I place the specimen 

 in this genus. It is more of a Ctenophyllum or Ptilophyllum which, how- 

 ever, cannot be decided from the material before us. Until better material 

 be obtainable, it is not worth while discussing the relationship of this species 

 to forms previously described. It might also be compared with those species 

 of Zamites and Pterophyllum from the Urgonian strata of Greenland de- 

 scribed by Heer. 



PODOZAMITES, Fr. Braun. 



Podozamites? sp. 



PL I. fig. 31. 



Newton and Teall, in their paper cited above, mention the occurrence of 

 pmnae resembling those of Podozamites. I am, however, not fully convinced 

 that the specimens represented on their plate 38, figs. 11 and 12 — or at any 

 rate their fig. 11 — should not rather be classed as Feildenia. On the other 

 hand it is not quite impossible that our specimen plate I, fig. 31, which 

 shows about 18 fine veins, should really be referred to Podommites; in 

 which case it would be yet another species of Gycadales which has been 

 found in Franz Josef Land.
