TH. G. HALLE, A GYMNOSPERM WITH CORDA1TEAN-LIKE LEAVES. O 



Phyllotenia, notwithstanding the obscure nature of that genus 

 In the shape and attachment of the leaves there seems to 

 be, at any rate, a greater resemblance to Phyllotenia longi- 

 folia than to any other fossil that may be considered pos- 

 sibly allied to the Swedish plant. This differs however in 

 the closer venation and broader bases of the leaves and in 

 the distinct, transversely elongated leaf-scars. Regarding 

 these facts a specific identification did not seem advisable. 

 The accepting of the name Phyllotenia should not be regard- 

 ed as involving an attribution of the Swedish species to the 

 Ginkgoales. The possibility of an affinity in this line can 

 not be denied, but it seems more probable that the Swedish 

 species is related to the Coniferales or perhaps rather to the 

 Cordaitales. Till better material be procured, it is however 

 impossible to arrive at even a provisional opinion.
