later papers. Krejicl (1853) wrote in Bohemian, as did Renger 

 in 1866. Renger (1866 a) had a paper on the Cretaceous tree- 

 ferns of Bohemia. Important work was done bj' Feistmantel 

 (1870, 1872 & 1874) and by Btur (1873), hut the deposits are 

 principally known through the publications of Velenovsky. 

 On the Dicotyledons we have Velenovsky's papers published in 

 1882 a and b, and 1883. A special monograph on the Gymno- 

 sperms appeared in 1885. Further papers on the rest of the 

 flora followed in 1886 and 1887 ; in 1887 a a paper appeared 

 on the Cenomanian plants, and papers in 1888 a, 1888 b (on 

 ferns) and 1889 complete a series of works covering the floras 

 of numerous localities and dealing with most of the families of 

 plants. The most noted localities are perhaps Lipenec, Raudnitz, 

 Clilomek, Vyserovio, and Kaunic. Bayer carried on the work 

 and published in 1893, 1890 and 1899 ; while Fritsch in 1877, 

 1883, 1889, 1S93 and 1897, issued a series of papers dealing 

 with the geology of the deposits, in the later parts of which 

 Bayer deals with the plants. In 1901 Fritsch and Bayer pub- 

 lished an important monograph on the Cretaceous plants of the 

 Perucer Beds of the country, which summarises and brings 

 together the previous work on the deposits of this age in 

 Bohemia. In 1901 Marik also published a paper, with plates, 

 in Bohemian. 



linger, in 1865, described a few plants from Hungaby, and 

 Staub (1888) recorded some Cenomanian plants from Nadrog. 

 Tuzspn (1908) has added an illustrated paper on the fossil flora 

 of this region. 



For Moravia, Heer (1869 a) wrote a large memoir on the 

 Cenomanian deposits at Moletein, near the Bohemian frontier. 

 Krasser, in 1889 and 1896, and Krasser with Kubart (1906) 

 added to the Cretaceous flora of Moletein. The specimens are 

 leaf-impressions, many of them dicotyledonous. 



A number of Cretaceous plants from the Island of Lbsina 

 were described and illustrated by Kerner in 1896. 



BELGIUM. 



Coemans in 1867 and Briart and Cornet (1867) described 

 the Belgian Cretaceous plants probably of the age of the Gault, 

 Coemans dealing with a comparatively small number of plant- 

 impressions.
