The second is a supposed grass, the last a cycad, aud the balance are 

 indefinite fuooidal-like remains. 



Portugal 



The Lower Cretaceous of Portugal furnishes a nearly complete section 

 largely the result of the stratigraphic and paleontologic studies of Chof- 

 fat. The fossil plants have been elaborated for the most part by the late 

 Marquis Saporta, whose large work appeared in 1894.^ The only con- 

 siderable previous work on these floras was the valuable contribution by 

 Heer in 1881.' 



The Portuguese deposits are of great interest, not only because of the 

 similarity in floral evolution with the Potomac, shown by the contained 

 floras, but also for the reason that they are largely checked by inter- 

 calated marine faunas.^ Saporta records the following species from 

 Portuguese beds classed as JSTeocomian. It is needful to point out that 

 this author's specific lines are finely drawn, resultiiig in a multiplication 

 of species scarcely warranted by the character of the materials.
