Bombax sepultijlorum Saporta,' based in the 

 first instance on the remarkably preserved 

 remains of flowers at Aix in Franco (Saimoisian) 

 but afterward correlated with the foliage which 

 had been originally described by the same 

 author as Knightites.= The leaves of Bomhax 

 sepultijlorum are moi-e jironiinently and ser- 

 rately toothed and are \ery close to those of 



Ceuomunian of Bohemia, referred by Vele- 

 novsky to Alalia coriacea ' and subsequently 

 transferred to the genus Dewalquea.^ The 

 broader forms of this type (for example, PI. I, 

 figs. 1, 2, 4, of Velenovsky, 1884) are very much 

 hke Bombacites, but the narrower forms sug- 

 gest a relationship with Ortopcniax oxfordensis. 

 Aralia coriacca has been identified by Hollick ^

 of the existing species Bomhax keptaphyllum. 



Among antecedent forms that may be men-
