250 Berry: Mp:sozoic flora of the coastal plain 



this resemblance cannot be construed as a proof of identity be- 

 cause of the incompleteness of the New Jersey material, conse- 

 quently the present form is here renamed in allusion to the locality 

 from which it was collected. 



Occurrence : Sayreville',

Populus orbicularis (Newb.) comb. nov. 



Phyllites orbiailaris Newb. Fl. Amboy Clays 130. //. 2^, f. 7, 8. 

 1896. 



Leaves orbicular, very slightly emarginate and slightly decur- 

 rent from the rounded base to the apparently short petiole, length 

 about 5 cm. and breadth usually two or three millimeters less than 

 5 cm. Margin entire. Midrib moderately stout. Secondaries 

 camptodrome, relatively coarse, about 6 pairs, subopposite, branch- 

 ing from the midrib at a wide angle, less curved than in the pre- 

 ceding, and inclined to be somewhat flexuous, 



Newberry calls attention to the resemblance of this species to 



Populus hyperborea Heer, but is quite positive that it is not related 



to Populus, The writer does not share this opinion. Unless we 



are prepared to discard Populus for Phyllites in a large number of 



cases this species should surely be referred to the former genus. 



It is a remarkable coincidence, referred to in the present connection 



only because of its general interest, that the type of Sternberg's 



form 



Populu 



dropped eventually in favor of some other name. 



The present species is based upon scanty but perfect material 

 confined to the Sayreville horizon. 



Occurrence : Sayreville.
