The Barremian Stage 

 Portugal 



The floras classed as probably of Urgonian age in Portugal are not all 

 precisely fixed in the Lower Cretaceous section, and some of the species 

 in the following list may be from the Aptian, a matter of no great moment 

 in the present connection. In common with the floras from the other 

 horizons in the Portuguese Mesozoic, the Barremian flora was collected 

 through the efforts of Choffat and elaborated by Heer and Saporta, and 

 large collections in the hands of the latter at the time of his death have 

 never been described.
