Lesquereux separates the Dakota leaves of Sterculia from 
Aralia merely on account of the ‘‘ primary divisions and pri- 
mary nerves from the top of the petiole.” This character, 
which I do not consider diagnostic, would refer this leaf to 
Aralia as the lateral primaries branch from the midrib a con- 
siderable distance above its base. The venation is some- 
what similar to the Dakota Sterculza reticulata Lesq. (FI. 
Dak. Group, p/. 34. 7. 10), and also to that of Aralia trans- 
verstnervia Sap. & Mar. described by Hollick from Oak- 
neck, Long Island (Bull. Torrey Club, 21. 54. Af. 176.7. 7. 
1894) which leaf he does not consider an Aralza. 
In outline this leaf resembles Sterculia lugubris Lesq. ex- 
cept that the primaries are not basal; whether the lobes were 
produced to the length they are in that species is of course 
conjectural. Our fragment is also somewhat similar in out- 
line to the fragment (Fl. Amboy Clays, f/. 26. f. 2) referred 
by Newberry to Aralia quinguepartita Lesq., in which how- 
ever the venation is unfortunately obliterated. Hollick’s 
Sterculia sp. (2. c.) probably belongs here; his f 4 is the 
fragment of a much smaller leaf, but his larger fragments 
(/. 5-7) might well be the acutely tipped lobes of our leaf, 
the venation of the two corresponding very well. 
Our leaf also has somewhat the appearance of Aralia 
Jorgensent Heer (Fl. Foss. Arct. 7: p/. roz. f. 1) but the 
sinuses are not quite so deep. It might further be compared 
to Aralia Wellingtoniana Vaughanit Knowlton from the 
Woodbine formation of Texas (Dakota). The latter is tri- 
lobed, the lobes slender and entire; not figured, however.

Sterculia Snowii bilobata var. nov. FY. 43. /f. 7. 
Sterculia Snowid is known from the Dakota Group of Kan- 
sas and New Mexico and the Cheyenne Sandstone at Belvi- 
dere, Kansas. The specimen from the Matawan here figured, 
in its outline approximates Lirtophylum Beckwithit Lesq., 
from the Dakota Group, but the venation is radically differ-
