256 The Upper Cretaceous Floras of the World 



With the exception of the few woods described by Conwentz ' no recent 

 additions have been made to the Cretaceous floras of Sweden. The fol- 

 lowing species are recorded : = 



Acerites f cretaceus Nilsson 

 Alnites ? friesii Nilsson 

 Comptonites t antiquus Nilsson 

 Cycadites nilssonianus Brongniart 3 

 Pinus nathorsti Conwentz 

 Salicites f wahlbergii Nilsson 

 Weichselia erratica Conwentz 



England 



In England the whole of the Upper Cretaceous is of typically marine 

 origin and consequently has not yielded any land plants except a few fir 

 cones, drift wood and rare and fragmentary leaves of dicotyledons in the 

 Lower Chalk. These have been mentioned in a few scattered papers/ 

 and as the British Museum has recently undertaken a report on Cre- 

 taceous floras 5 no attempt will be made to list the few and unsatisfactory 

 forms in the literature, especially since in their present state they offer 

 nothing of either botanical or geological significance.
