286 The Upper Cretaceous Floras of the World 



The earliest publication dealing with the Bohemian Cretaceous plants 

 is the monumental work of Sternberg, 1 to which both Presl and Corda 2 

 made valuable contributions. Several plants from this area, including 

 Dammarites albens, Thuites alienus, Thuites gramineus, Caulerpites 

 fastigiatus, Steinhauera minuta, Protopteris punctata, etc., are described 

 and figured, and both the Cenomanian and Turonian stages are repre- 

 sented. 



Corda, another native of Bohemia, was not only an eminent histologist 

 but an earnest student of fossil as well as recent plants, and had not his 

 life terminated at the early age of 39 in the tragic sinking of the Bremen 

 steamer " Victoria " in mid- Atlantic in 1849, he would unquestionably 

 rank as one of the more eminent students of fossil plants. His work for 

 Sternberg paved the way for his two other principal works, " Beitrage 

 zur Flora der Vorwelt," Prague, 1855, and " Die fossilen Pflanzen der 

 bohmischen Kreide-formation." The first of these works deals mainly 

 with Carboniferous plants, but contains careful descriptions and illus- 

 trations of Protopteris, Tempskya and Krannera from the Bohemian 

 Cretaceous. The second forms a part of Keuss's " Versteinerungen der 

 bohmischen Kreideformation," Stuttgart, 1846, and contains descrip- 

 tions and figures of a considerable number of plants from both the 

 so-called Planer and Quader of Bohemia. 



The abundant flora contained in the beds of Perutz, the so-called 

 Perucer Schichten was discussed in several short papers by Krejci, 8 

 Renger, 4 Feistmantel, 5 Stur," Fric, 7 and Kodr. 8 In 1869 in the first volume
