128 THE RARITAN FLORA. 



2.2 cm. While their distal portions are broken off they were 

 apparently 12 cm. or 13 cm. in length. Subsequently, remains 

 of a similar nature froiji elsewhere in Greenland were referred 

 by Heer to this species, among them, the only complete leaf (loc. 

 cit. pi. Ixii, fig. 6) which shows a blunt apex. It is with this 

 latter specimen that the Raritan leaves show the most marked 

 affinity. The latter are found detached, but are unsymmetrical, 

 as is the case with the leaflets of many trifoliate forms. They 

 have a rather slender midrib and 6 or 8 pairs of very thin as- 

 cending camptodrome secondaries, the apex is blunt and the 

 base is attenuated. They are about 7 cm. in length by 1.4 cm. 

 to 1.7 cm. in greatest width. There seems to be little room for 

 doubt but that they are correctly identified. 



This species has a wide range, if reliance can be placed on the 

 published records, which include Staten Island, North Carolina 

 and Alabama.

Dewalquea trifoliata Newb. 



Dewalquea trifoliata Newb., Fl. Amboy Clays, 129, pi. 22, f. 

 4-7, 1896. 



Description. — Leaves trifoliate. Leaflets linear lanceolate. 

 While the tips are missing on all of the specimens the apex was 

 apparently acuminate. Base cun^ate and decurrent, in some 

 instances continued downward and joining that of its fellow leaf- 

 lets, inequilateral in the lateral leaflets. Size variable, ranging 

 from about 8 cm. to 12 cm. in length and 1.2 cm. to 2 cm. in 

 breadth. Margins entire throughout. Midrib medium, slightly 

 flexuous. Secondaries numerous, thin, more or less obsolete, 

 apparently camptodrome. 



A number of specimens, all incomplete, have been collected 

 from the Woodbridge clays and several are figured in Prof. 

 Newberry's monograph. The genus is characteristic of the 

 Upper Cretaceous and Lower Eocene and its botanical affinities 

 are still considered doubtful, although it is usually classed with
