from the Upper Cretaceous. In 1890 Marion had a short paper 

 on the Turonian ; Saporta described species of Nelumhmm from 

 the Uppermost Cretaceous (Danian) ; and Vasseur recorded a 

 Turonian Flora near Martigaes. Fliche (1892, 1893) described 

 two Albian plants, and in 1894 had a paper on the fruotiflcalions 

 of Cenomanian palms. In 1896 he published a large illustrated 

 paper on the Albian and Cenomanian deposits, and in 1900 one 

 on the Lower Cretaceous. 



Lignier (1907) described several specimens of wood from 

 Normandy, with the internal structure petrified.

Phussia. — The deposits of Aix-la-Chapelle (or Aachen) are 

 classical ground for the palaeobotanist, and were first worked by 

 Goeppert (1812 b). The locality, however, is generally associated 

 with the name of Deboy, and then Dobey & Ettingshausen. 

 Debey (1848 a, 1848 b, 1849, 1860) published several short 

 papers on the Aix Cretaceous plants, and then with Ettingshausen 

 (1859 A & b) prepared two large, well-illustrated monographs 

 on the " Thallophyten " and the " Aorobryen" of the Cretaceous 

 of Aix and Maestricht. Debey made large collections and was 

 apparently preparing voluminous further publications, but in 

 1877 only a very short note appeared about a paper he gave on 

 the Coniferse of the Cretaceous of Aix. His collections with 

 the specimens bearing unpublished names, are evidence of the 

 richness of the deposits. In 1890 Lange also contributed to our 

 knowledge of these beds. 



The Senouian sandstones of Quedlinburg and neighbourhood 

 have also yielded an important Elora, first noticed by Geinitz 

 (1850 d), but more exhaustively described by Stiehler (1854, 

 1857, and especially 1858). Heer (1871 a) made a small 

 contribution, and Eichter has continued the work during more 

 recent years. In 1899 b he published a paper on the Conifers of 

 Guedlinburg, and in 1901 a mbnograph on the Neooomian plants 

 of the same district. In 1905 he described numerous Senonian 

 plants, and published a valuable revision of the genus Credneria. 

 In 1906 he prepared a similar revision of Hausmannia, with 

 notes on the Lower Cretaceous Flora ; and in 1909 there 

 followed an equally exhaustive monograph on Nailiorstiana.
