On the OccuERENCE of LiASsic Plants in the Catjcasus, and in the 

 Alboetjs (Elbetjs) Eange (Peesia) ; and on the Disteibution of the 

 LiAssic Floea *. By Prof. Dr. H.R.Goeppeet, Por.M.G.S.,&c.,&c.

 Petersbourg,' vol. iii. No. 4 (1861), pp. 292-299.] 



Fossil plants from the Lias (two species otZamites) were first figured 

 by De la Beche (Trans. Geol. Soc. 2nd ser. vol. i. pi. 7. figs. 2 & 3). 

 Count Miinster discovered a larger number on the Theta near Bay- 

 reuth, which, preserved in the Munster Collection, were described 

 and figured by Count Sternberg and myself. Prof. C. W. F. Braun, 

 of Bayreuth, extended these discoveries, and has supplied the most 

 numerous and important contributions made since that time for 

 estabhshing an independent flora for the Lias-formation. This flora 

 may be said to be characterized by the prevalence of Cycadem (pro- 

 bably more than half of the 120 to 130 species constituting this 

 flora belong to the Cycads) and of Ferns with reticulate venation, 

 approaching more closely to the Ferns of the Keuper than to those of 

 the Middle Jura. In 1843 I recognized the Liassic flora of Gaming 

 in Upper Austria, afterwards published by Ettingshausen, as weU as 

 that of Halberstadt and Quedlinburg, on which Germar furnished a 

 memoir. Berger has described Liassic plants from the neighbourhood 

 of Coburg ; Brongniart and Hisinger, those of Hor in Sconia ; Kurr, 

 those of Wurtemberg ; Andrae, those of Steierdorf in the Banat ; and 

 Buckman, those of Strensham in "Worcestershire. The plants of the 

 Coal of Eichmond, Virginia, suggest, according to Jackson and Mar- 

 ecu, the Lias -formation.
