138 THE RARITAN FLORA. 



Description. — A considerable variety of forms are referred by 

 Professor Newberry to this species; most of these are frag- 

 mentai-y and depart somewhat from the usual form ; for example, 

 his fig. 2 shows the terminal portion of the lobes with several 

 acute marginal teeth. This author's fig. i is here taken as the 

 typical form, and it may be described as follows : Leaves oblong 

 in outline, of large size, 1 1 cm. in length along the midrib by 

 about the same distance in greatest width. Apex emarginate. 

 Base truncate. Laterally there are three or four incipient lobes 

 or points separated by wide, shallow, rounded sinuses, the lowest 

 pair being almost half the distance from the base to the end of 

 the midrib. Petiole long and stout. Midrib stout. Secondaries 

 slender but well marked, numerous, about 12 pairs, sub-opposite, 

 mostly camptodrome, usually sending branches to the marginal 

 points, occasionally one runs direct to a marginal point; they 

 branch from the midrib at a wide angle, about 65°, and are com- 

 paratively straight in their courses and consequently approx- 

 imately parallel. 



The remains of this species are rather infrequent and frag- 

 mentary, on the whole they indicate a leaf surprisingly like that 

 of the modern tree and almost identical with those modem leaves 

 which are more or less quadrangular in outline, with shallow 

 rounded sinuses and from 2 to 5 marginal lobes on each side. 



This species is confined to the Woodbridge locality, with the 

 exception of a single extremely doubtful fragment from Glen 

 Cove, Long Island, which Hollick tentatively identifies with it.
