In 1888 Stur 2 described several species of Jurassic plants from 

 Grojec in Galicia, and more recently Eaciborski 3 has published an 

 important memoir on the fossil flora of the Cracow district obtained 

 from the mines of Grojec and other localities. Many of Raciborski's 

 species are undoubtedly identical with East Yorkshire plants ; and 

 the flora as a whole presents a closer agreement with that of the 

 Inferior Oolite than with any other period. Raciborski recognizes 

 the correspondence between the Cracow plants and those from the 

 Yorkshire coast, but from the presence of Thinnfeldia and some 

 other Rhastic types he concludes that the flora he describes is 

 slightly older than the English flora. 



The following list, which does not include all the species, 

 illustrates the striking Lower Oolite facies of the Cracow flora : 



Danaea microphylla, Rac. 



Todea, Williamsonis (Brongn.) = Todites Williamsoni (Brongn.). 



T. princeps (Presl). (Raciborski's figures do not afford satisfactory evidence of 



the occurrence of this species.)

Dicksonia Heerii, Rac. = Coniopteris hymenophylloides (Brongn.).
