Pinus elliptica Trauts. 



Beussia pectinata Goepp. 



Ruffordia Ooepperti (Sphenopteris auerbachi Trauts.) 



Thuyites ecarinatus Trauts. 



Both Valanginian, Hauterivian and Barremian deposits are repre- 

 sented in central Eussia these three stages being capable, according to 

 Pavlow, of a two-fold division into Petchorian below and Simbirskian 

 above. The fossil plants, according to recent authoiifcies, are consid- 

 ered of Barremian age. 



A number of forms recorded in the earlier work of Eichwald (loc. cit., 



1865) are not mentioned by Trautschold, and while they have little 



precise value, either botanical or stratigraphical, they may be given for 



the sake of completeness. They are: 



Araucarites crassifolius Corda 

 Amygdalus taurica Eichwald 

 Gerasus meridionalis Eicliwald 

 Cupressinoxylon ucranicum Goeppert 

 Cycadites afflnis Eichwald 

 Gycadites contiguus Eichwald 

 Eguisetites notaMlis Eichwald 

 FascicuUtes amMguus Eichwald 

 Geinitzia prisca Eichwald

 Psammopteris knorriceformis Eichwald

The most interesting, as well as the most extensive, flora which has 



been referred to' this horizon in the Lower Cretaceous is the Kome flora 



of Heer ^ found along the north side of the Nugsuak peninsula in West 



Greenland, in latitude 70° 45' north (215 metres). Since White and
