There are others which are most frequently met with upon 

 the chalk, although they also occur on other strata; these 

 are, for example : — 



Tozzia alpina Anemone narcissiflora 



Gentiana ciliata Thalictrum aquilegifolium 



G. acaulis Aconitum cammarum 



Daphne Mezereum Alchemilla alpina 



Astrantia major Rosa alpina, &c. 



The differences which may exist between the vegetation of 

 the different kinds of calcareous strata, are still less distin- 

 guishable ; I have however endeavoured to arrange a table of 

 the species which more particularly inhabit each of these for- 

 mations. 



Thus there exist plants peculiar to the alpine limestone, the 

 metalliferous limestone, the limestone of Rettenstein, and the 

 primitive limestone, or that of Brennthal, the veins of which 

 traverse our argillaceous schist.
