On the Tertiary Flora of Bilix, North Bohemia. 

 By Prof. C. yo:s- Ettingshausei^. 



[Proceed. Imp. Geol. Inst. Vienna, February 5, 1867.] 



Prof. C. vox Ettingshausex has published, in the Transactions of 

 the Imperial Academy of Vienna (vol. xxvi.), the first part of his 

 description of this flora, comprising the Thallophytes, the Cryp- 

 togams, Monocotyledons, Coniferaj, and Jnliflorae, illustrated by 

 thirty plates. The flora of Bilin is contained in four deposits, 

 namely, (1) polishing shales of Kutschlin; (2) freshwater limestones 

 of Kostenblatt ; (3) menilites and opals of the Schichow valley ; 

 and (4) plastic clays, bituminous shales, and sphaerosiderites. 

 Taken as a whole, the Tertiary flora of Bilin is richer in species and 

 more varied in character than any other known local flora in the 

 Austrian empire. The species described in this flrst part are dis- 

 tributed thus : — Uluacecel, Floridece 2, Cliaracecb 1, HyplwmyceUe2, 

 Pyrenomyce 18, Equisetacece 1, Polypodiacece 7, Salviniacece 3, 

 Oraminece 17, Cyperacece 2, Butomew 4, Juncacece 1, Smilacece 1, 

 Muscacece 1, NaijadecB 3, Typliacect 3, Palms 2, Cupressinece 7, 

 AbieiinecB 4, Taxinece- 1, Casuarinece 2, Myricacece 3, Behdacece 8, 

 Cupuliferce 23, Uhnacece 7, Morece 25, Artocarjpece 5, Plaianece 1, 

 Bcdsamijiorce 1, Salicinece 5, Polygonece 2, Nyctaginece 1.

On ilie Cretaceous Flora of I^iederschoxa, Saxoxt. 

 By Prof. C. vox Ettixgshausex. 



Proceed. Imp. Geol. Inst. Vienna, January 17, 1867.] 



This flora is remarkable in its off'ering remains of the most ancient 

 Dicotyledonous plants hitherto known. The plants are terrestrial 

 and of an unmixed tropical character, numbering forty-two species, 

 distributed as follows : — Ferns 4, Gymnosperms 5, Monocotyledons 2, 

 Apetals 16, Gamopetals 1, Dialypetals 11. The Gymnosperms 

 and Apetals are numerically to the Dicotyledons of higher organi- 

 zation as 2 to 1. The same proportion exists between the extinct 

 genera and those of the recent period. Thirteen species of the 

 flora of Niedersehona are met with in other deposits, and among 

 them are characteristic species of the Cretaceous period. One 

 species occurs likewise in the V^'^ealden, and another in Tertiary 

 strata. The prevalence of Proteacece and Legumiyiosce connect this 

 flora on the one hand with that of IS'ew Holland, and on the other 

 with that of the older Tertiary period, It differs from both in 

 containing so large a number of Gymnosperms and Ferns, con- 

 necting it with Secondary floras of a more remote date. Very 

 few analogous forms are known as existing species, but a larger 

 number are found fossil in Tertiary deposits.
