178 Berry: Mesozoic flora of the coastal plain 



Because of the well-known variability in fossil Sterculia leaves 

 both from this country and abroad, the original two-lobed speci- 

 men from Clififwood bluff was referred to Lesquereux's species 

 cited above, and was considered to be a small bilobed form of the 

 same species, which ordinarily bore rather larger leaves. Subse- 

 quent collections, however, at different localities far removed from 

 Cliffvvood bluff, show that these small leaves are uniform in size 

 and may be indifferently two or three lobed, so that it seems 

 desirable to consider them distinct from the ordinarily much larger 

 Sterculia mucronata Lesq. of the west, from which it may be dis- 

 tinguished by its much smaller size, its less conical lobes, di- 

 rected upwards instead of laterally, and the fact that in the former 

 the leaves are palmately 3— 5-lobed and the primaries are three in 

 number and are palmately arranged from the top of the petiole. 



Formation — Magothy. 



Localities — Cliffvvood bluff (type) and pits of Cliffvvood Brick 

 Company, N. J., Deep Cut, Del., and Grove Point, Md. 



Sterculia cliffwoodensis Berry, Bull. N. Y. Bot. Gard. 3: 88. 



pt-43-f-5- 1903- 



Originally described from Clififwood bluff, N. J. A single 



broken fragment from Deep Cut, Del., has one lobe preserved for 



a distance of 10 cm., which must have given the perfect leaf much 



the appearance of Sterculia lugiibris Lesq. 



Thymeleales 



Laurus Hollicku Berry, Bull. N. Y. Bot. Gard. 3: 79. pi. 52. 



f. 4. 1903. 



This is one of the commonest species in the Magothy forma- 

 tion, to which it is confined, and has been collected at Morgan and 

 Clififwood bluff, N. J., at Deep Cut, Del., and at Grove Point, Md. 



Laurus plutonia Heer, Fl. Foss. Arct. & : 75. pi. 19./. id, 2-4, 



. et seq. 1882. 



This widespread mid-Cretaceous species has been found at the 

 following localities in the Magothy formation : Morgan, Cliffvvood 

 bluff and Clififwood Brick Co., N. J., and Grove Point, Md.
