242 PODOZAMITES. 



by Nathorst from the Rhsetic beds of Bjuf, in which the lower 

 part of the petiole is clasped by a few imbricate bracts bearing 

 a striking resemblance to bud-scales. 



The structure of the epidermis of the pinna? is described by 

 Schenk, and regarded by him as an argument against an alliance 

 with the genus Agathis ; the form of the epidermal cells, how- 

 ever, does not, I believe, constitute an important objection to the 

 suggestion that Podozamites may represent the shoot of a Conifer 

 rather than the pinnate frond of a Cycad. 



In addition to the type represented by Podozamites lanceolatus, 

 there are others characterized by broadly oval segments, 1 

 which suggest a comparison with the broad leaves of Agathis 

 Dammar a, Rich. 



It is unsatisfactory to express a definite opinion in favour of 

 assigning Podozamites to the Conif erao rather than to the Cycadacea; 

 on such evidence as is before us, but I am disposed to favour the 

 view that the plants, which it has been customary to refer to 

 Braun's genus, may be more correctly compared with the Conifer 

 Agathis than with any recent Cycad.
