M.Brongniart on the different Floras which 



In comparing this flora with that of the gres higarre of the 

 Vosges, and with that of the Has, it is seen that it has nothing 

 in common with the former except the Palaoxyris^ which appears 

 extremely near that of the gres higarre', on the other hand, it 

 resembles the flora of the lias or of the oolite in the Ferns, seve- 

 ral of which are specifically identical or exceedingly near, and in 

 the species of Nilsonia and Pterophyllum, which are also identical 

 or very near species to those of the lias.
