196 THE RARITAN FLORA. 



This species is common in the upper Raritan and has a re- 

 corded range of considerable extent in somewhat later forma- 

 tions. It is recorded from the Magothy formation of New 

 Jersey and Marjdand, the Bladen formation of North Carolina 

 and the Tuscaloosa formation of Alabama. 



Occurrence. — ^South Almboy, Hylton Pits.

Description. — Leaves elliptical in outline, 7-8 cm. long by 

 about 4 cm. wide, with acute apex and base, the latter slightly 

 decurrent and inequilateral. Margin entire, very slightly un- 

 dulate. Midrib slender and straight. Secondaries slender, about 

 7 pairs, opposite or alternate, branching from the midrib 

 at an an^le of about 45°, and strongly curved upward, approxi- 

 mately parallel and camptodrome; they increase in length from 

 the apex to the base, the lower ones sweeping upw^ard in strong 

 arches parallel with the margin and all drawn inward toward the 

 apex. 



With the exception of the delicate and somew-hat flexuous 

 character of the venation, these leaves are strictly comparable 

 with those of Cornus, good species of which, very similar to the 

 Raritan leaf, occur in the Dakota Group, in Greenland and in 

 the Magothy formation of Maryland. Doubtless the Raritan 

 species will eventually be referred to that genus, meanwhile the 

 present generic appellation is a sufficient index of its relationship. 



This species is rather rare, and as indicated above, serves to 

 ally the Raritan with somewhat younger formations. 



Occurrence. — Woodbridge, Milltown. 



Collections. — U. S. National Museum, N. Y. Botanical Garden.
