246 Berry : Mesozoic flora of the coastal plain 



Both of Heer's types which are here united with Newberry's 

 species are small fragments of ultimate pinnae, which their author 

 confesses are very similar, a fact well brought out by a comparison 



_ y 



of the figured specimens. The material from Woodbridge, N. J., 

 is more ample, and, as may be seen lower down on the frond, the 

 pinnules become toothed and finally pinnatifid, a feature not shown 

 in the s;cant material from Greenland. There is slight reason, 

 however, for doubting their identity, Newberry himself having 

 pointed out that Dicksonia horealis of Heer was probably identical 

 with his Amboy Clay species. 



Although common at Woodbridge, this species has not been 

 found elsewhere in the coastal plain except for a single specimen 

 which the writer discovered recently in the Tuscaloosa formation 

 of Alabama. It is present at both the Atane and the Patoot hori- 

 zons in Greenland.

I 



Asplenium raritanense sp. nov. 



Frond and pinnae unknown. Pinnules small, r.33 cm, long 

 by 10 mm. in greatest breadth, ovate, with narrow somewhat 

 straight-sided base, palmately divided into one terminal and two 

 pairs of lateral, rounded, not deeply parted lobes ; margin entire 

 at base and in sinuses, sharply toothed on the lobes. Venation 

 flabellate; about seven veins entering the base of the pinnule, 

 these soon forking dichotomously, the ultimate divisions terminat- 

 ing in the marginal teeth. [Plate i 8, figure i .] 



This species, which is quite unlike anything heretofore known 

 from the Raritan formation, is unfortunately based on the single 

 tiny pinnule figured. The general form and habit remain unknown. 

 It is markedly distinct from any described fossil species known to 

 the writer, although showing some points of resemblance to 

 various arctic species referred to this genus by Professor Heer. 

 Since the chances of more representative material being found 

 are remote, it has seemed best to describe it under the above 

 name. 



Occurrence: Hylton Pits.
