280 The Upper Cretaceous Floras of the World 



• Dresden. — The only other important Upper Cretaceous plant beds 

 in the Kingdom of Saxony are those from the Quader in the vicinity 

 of Dresden and Dippoldiswalde first studied by Glocker and elaborately 

 (but poorly) described by von Otto * about the middle of the last century. 

 The flora consists, for the most part, of poorly preserved and indefinite 

 remains. It is younger than that at Niederschoena and probably cor- 

 responds to the middle horizon of the Cenomanian or the zone of Ostrea 

 carinata of the recent sections by Petraschek. Following is a list of 

 Otto's determinations : 



Arundinites wohlfarthi Otto 



Asterosoma radiciforme Otto 



Carpolites 



Credneria 



Chondrites fursillatus Roemer 



Cunninghamites mantelli Geinitz 



Cunninghamites oxycedrus Presl 



Cupressinea insignis Geinitz 



Cylindrites spongioides Goeppert 



Dilleniacew 



Geinitzia cretacea Endlicher 



Halyserites reichi Sternberg 



Keckia annulata Glocker 



Keckia cylindrica Otto 



Keckia nodnlosa Otto 



Keckia vesiculosa Otto 



Palmacites varians Corda 



Pinus exogyra Corda 



Proteacece 



Pterophyllum cretosum Reich 



Pterophyllum germari Otto 



Sphwrococcites striolatus Presl 



Spongia ottoi Geinitz 



Spongia saxonica Geinitz 



Zamiostrobus 



This list could be considerably extended by searching through the 

 works of H. B. Geinitz who was such a voluminous writer on the German 

 Upper Cretaceous and who followed Ecemer in describing so many trails, 

 current markings, and similar objects in the Quader as fossil plants. It
