One species each of Isoetes, Equisetum, and Jungermannites are de- 

 scribed, the first being a very convincing type. There are 3 species of 

 Lycopodites, 22 species of ferns, 5 conifers, and only a single cycad. 

 The paucity of cycad remains is in remarkable contrast with most floras 

 of about this age, the Kome flora of Greenland and the Barremian flora 

 of Austrian Silesia each having 11 cycads. 



Saporta refers Delgadopsis and Protorrhipis to his Proangiosperms, 

 although the second is unquestionably a fern. The species of Poacites 

 and Bhizocaulon are considered as monocotyledons and CJiojfatia as a 

 dicotyledon, although the evidence for all of these forms is of a character 

 which is far from trustworthy. 



There are five species which are present in the Potomac flora and 

 several others which are closely allied types. 



France 



Eemains of plants in the marine deposits of the Barremian of France 



are scanty and unrepresentative.^ The recorded species include: 



Araucaroxylon barremianum Fliche 

 Cedrus Lennieri Saporta 

 Cedroxylon reticulatum Saporta 

 Cedroxylon barremianum Fliche
