Lesquereux (FI. Dak. Group, 249) characterizes these 
leaves as follows: ‘* Base decurrent, primary nervation pal- 
mately trifid and supra-basilar,” but he repeatedly fails to 
conform to his definition. Thus his A. acerzfolia, A. tenuz- 
nervis, A. dissecta and A. subemarginata lack the decurrent 
base, as do also five of Newberry’s Raritan forms. The pri- 
maries are generally subbasal and are basal in Lesquereux’s 
A. guinguepartita, A. notata, A. dissecta and A. Masont. 
I have been at a loss to distinguish between Sterculia and 
Aralia in the Matawan material; no mutually exclusive 
characters can be gathered from the published descriptions 
or figures, and as it would be useless to attempt a revision 
without an examination of all the collected material, I have 
been forced to follow the pernicious precedent above al- 
luded to.

Described originally from the Dakota Group of Kansas, 
Hollick has doubtfully referred two fragments from the clays 
near Cliffwood to this species. These fragments are so in- 
complete that the form of the leaf is more or less conjectural. 
The secondaries are straighter than in Lesquereux’s speci- 
mens and branch from the primaries at a wider angle. At 
the same time they seem to differ from my specimens from 
this formation which I have referred to Aralva Ravniana Heer.
