144 THE RARITAN FLORA. 



Description. — Trilobate leaves more or less hastate in outline. 

 Lobes conical, obtusely pointed, the middle one the larger. The 

 lateral lobes are generally directed horizontally, thus the base is 

 truncate in extreme forms, in others it is broadly rounded, while 

 still other fragments indicate that it was cuneate in some speci- 

 mens. These leaves vary considerably in size and appearance, 

 some of them approaching Sassafras progenitor Hollick in ap- 

 pearance. They are about lO' cm. to^ 12 cm. in length, by about 

 the same distance from tip tO' tip of the lateral lobes. Primaries 

 3, somewhat flexuous, diverging a considerable distance above 

 the base, the short and stout petiole continuing upward in the 

 base of the leaf in undiminished size to this point of divergence. 

 Angle between the lateral primaries and the midrib varying from 

 32° to 70°, being usually nearer the latter than the former figure. 

 In one specimen there are 2 pairs of laterals below the point of 

 divergence of the primaries. 



This species shows co'nsiderable diversity of characters. It 

 is quite common at the Woodbridge horizon and is also^ reported 

 from Long Island and Marthas Vineyard. Its relation to the 

 modern Sassafras is very doubtful and it seems to be allied to 

 some oi the P.aritan fo^rms which Newberry identifies with 

 Aralia.
