Group, 134- /^- i-/-y^ i-J- 1892. Hollick, Bull. Geol. 

 Soc. Am. 7: 13. 1895. Nevvb. Fl. Amboy Clays, 116. 

 //. 28. /. 4. 1896. 



A widespread species recorded from the Atane schists, 

 Greenland; Dakota Group, Kansas; Raritan, Woodbridge, 

 N. J. ; and the Cretaceous at Martha's Vineyard. 



If Newberry has correctly identified Fl. Amboy Clays, pi. 

 28 if. /, as the above species then our fragment undoubtedly 

 belongs to the same species. It is the same size as New- 

 berry's leaf ; the angle of divergence of the lateral primaries 

 is a trifle greater however, and the primary venation is 

 stronger, agreeing with Lesquereux's and Heer's leaves in 

 the latter particular. Both the New Jersey leaves are smaller 

 than the Dakota and Greenland specimens and have relatively 

 narrower lobes. Unfortunately the basal portion of the Cliff- 

 wood leaf is gone, so we do not know whether or not there 

 was an extra pair of laterals springing from the base of the 

 midrib. This is a feature of all the leaves which Lesquereux 

 has referred to this species, but is wanting in Heer's pi. j8y 

 f. J, and is also wanting on one side in the Raritan leaf. 



The leaf which Newberry describes as a new species (/. c. 

 11^. pi. 28. y. j), under the name of A7'alta patens^ should 

 in all probability be considered as a form of his A. Grocn- 

 landica with deeper sinuses and more divergent lobes, as he 

 suggests. Our leaf might also be compared with Cret. & 

 Tert. Flora, pi. ^. f. i, which Lesquereux considers Sassa- 

 fras actitilobum ; it is also much the same form of leaf as 

 Sterculia aperta Lesq., but larger ; and there is considerable 

 resemblance to the leaf which Heer refers to Sassafras Fcr- 

 retiana Mass. (Fl. Foss. Arct. 7: //. 97. y. 5). 



Aralia Mattewanensis sp. nov. PI. 4.3./. 2 ; pi. 46./. 6. 



A palmately four- or five-lobed leaf ; lobes oblanceolate in 

 outline (tips missing), with rather narrow sinuses nearly to 

 the base ; primaries rather stout ; a majority of the seconda- 

 ries branch at a wide angle and are nearly straight to within 

 a short distance of the margin, along which they arch. Leaf 

 coriaceous, if we may so judge from the obsolete venation.
