In 1888 Stur^ described several species of Jurassic plants from 

 Grojec in Gralicia, and more recently Eaciborski ' bas published an 

 important memoir on tbe fossil flora of tbe Cracow district obtained 

 from the mines of Grojec and other localities. Many of Eaciborski'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. Eaciborski recognizes 

 the correspondence between the Cracow plants and those from the 

 Yorkshire coast, but from the presence of Thinnfeldia and some 

 other Ehaetic types he concludes that the flora he describes is 

 slightly older than the English flora. 



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

 illustrates the striking Lower Oolite facies of the Cracow flora : — 



Danaea microphylla, Eac. 



Todea Williamsonis (Brongn.) ^Todites Williamsoni (Brongn.).

the occurrence of this species.)
