DENMARK. 



Bartholin * has recently figured and described some plant 

 fragments found in an erratic block of ferruginous sandstone from 

 the glacial deposits near Copenhagen. The specimens are for the 

 most part very imperfect, and their determination is a matter of 

 some uncertainty, but one or two of the species are represented 

 by more satisfactory examples : 



Ginkgo Huttoni = G. digitata, Brongn.

In 1872 Nordenskiold and Oberg obtained a collection of 

 Jurassic plants from Cape Boheman (lat. 78 22' N.), which 

 have been described by Heer 1 and lately revised by Nathorst. 3 

 This flora, consisting of a small number of species, is no doubt 

 approximately of the same age as that from the East Yorkshire 

 strata. 



Sphenopteris thulensis, Heer; cf. Conioptei-is hymenophylloidts (Brongn.). 

 Pecopteris erilis, Phill. (fragment too small to determine) = ? Klukia exilis (Phill.). 

 Taniopteris, sp. ; cf. T. vittata, Brongn.
