i88 THE RARIT^^N FLORA. 



Very little can be said in favor of the reference of this leaf to 

 Lesquereux's genus ProtophyUum, all of the species of which 

 differ from it in outline and marginal characters. Professor 

 Newberry places great reliance upon the character of the base, 

 but in the Raritan specimen this is decidedly auriculate and not 

 subpeltate and the veins in this part of the leaf are radiate and 

 not more or less parallel. Finally, the venation is distinctly 

 camptodrome and not craspedodrome, as. it is in Lesquereux's 

 detinition of the genus and in all other species which have 

 subsequently been referred to it. For these reasons it is here 

 placed in the genus Pterospermites, which seems to be a more 

 natural arrangement. It may be compared with Pterospermites 

 aiiriculatus Heer^ of the Atane beds of Greenland, which, while 

 somewhat different in outline, is a leaf of the same general facies 

 and is undoiibtedly congeneric.
