to it are suggestive of what Newberry called Aralia patens. The species 

 is more abundant in the somewhat later Cretaceous deposits of Marthas 

 Vineyard, Cliffwood Bluff, and Sullivan's Cove. It was described origi- 

 nally from the Atane beds of Greenland and is also present in considerable 

 abundance in the Dakota group of Kansas.

Description. " A. foliis amplis, coriaceis, laevigatis, quinquelobis, lobis 

 integerrimis, lobo medio maximo, basi valde contracto, ovali, lobis laterali- 

 bus oblongo-lanceolatis." Heer, 1882. 



This most striking species of Aralia, because of its large size, has always 

 been found in a fragmentary condition. Specimens showing all parts of 

 the leaf have now been collected, the Maryland material conclusively con- 

 firming the restoration of this leaf made by the writer in 1903 (op. cit.). 

 It also confirms the supposition made from the venation of the Xew 

 Jersey material, that instead of a broadly ovate median lobe, as Heer 

 supposed, this middle lobe was sublobate by the greater or less develop- 

 ment of a lateral lobe on each side, as shown in the accompanying restora- 

 tion based on the Maryland material. The species may be more fully 

 defined in the light of all of the material as follows : Leaves of large size, 

 ranging from 16 cm. to 21 cm. in length and from 19 cm. to 23 cm. in 

 maximum width, orbicular in general outline, deeply pinnate-lobate. 

 Apex of the terminal and lateral lobes bluntly pointed. Base broadly 

 cuneate. Margins entire. Texture subcoriaceous. Lobes usually seven in
