From Hollick (1930) (p. 71)

"Leaf oblong-obovate, 12 centimeters or more in length by 5.5 centimeters in maximum width, broadest above the middle, narrowed below to a rounded, truncate, obscurely inequilateral base; margin irregularly serrate-dentate; midrib slightly curved; nervation pinnate, craspedodrome; secondary nerves numerous, leaving the midrib at acute angles, the lower ones on one side of the leaf slightly spreading and branched toward their extremities, all craspedodrome to the larger teeth, the branches terminating in the smaller intermediate teeth."



From Hollick (1930) (p. 71)

"This strongly defined leaf is apparently an Ulmus, but it possesses features suggestive of the Betulaceae, like the Tertiary species Ulmus carpinoides Goeppert (1855) (p. 28, pl. 13, figs. 4 - 9 ; pl. 14, fig. 1). In fact, the resemblance of our specimen to Carpinus is perhaps more striking than it is to Alnus, but the prior publication of Goeppert's name, indicative of this reisemblance, precludes its application to our species. There is, apparently, no known Cretaceous species with which it may be even remotely compared."
