106 The Lower Cretaceous Floras of the World 



and in Hainaut. From this area Brongniart^ recorded five species of 

 characteristic Lower Cretaceous plants in 1849. These were Lon- 

 chopteris Mantelli, Pachyptcris gracilis, Brachyphyllum Oravesii, Za- 

 mites Brongniarti, and Carpolithus MantelU. 



Cornuel " recorded some additions to the flora in 1866 which he ob- 

 tained from beds of JSTeocomian age in the Paris basin, and Saporta ^ and 

 others have made minor contributions. The flora as a whole is poorly 

 developed, and has, in a country so rich in Carboniferous, Jurassic, and 

 Tertiary plant beds, attracted but little attention. The following forms 

 have been recorded: 



Brachyphyllum Gravesii (Pomel) Brongniart 



Eguisetum Burchardti Dunker (Carpolithus MantelU) 



Pinus aspera Cornuel 



Pinus gracilis Cornuel * 



Pinus elongaia d'Orbigny 



Pinus rhomMfera Cornuel 



Pinus submarginata Cornuel 



Protopteris Buvignieri Brongniart ' 



Sphenopteris Fittoni Seward (Pachyptcris gracilis) 



Sphenopteris Delgadoi Saporta^ (possibly same as Fittoni) 



Weichselia reticulata (S. & W.) Ward 



Zamitcs Brongniarti (Mantell) Brongniart 



England 



The flora of the English Wealden, using that term in the more re- 

 stricted sense for the Hastings beds and the overlying Weald Clay (H. B. 

 Woodward) is of interest not only because its flora is the only European 

 flora outside of Portugal which has been revised in recent years, but
