"Leaf 11 centimeters in length by 14 centimeters in width across the middle, orbicular-reniform, peltate; apex rounded, flattened, somewhat oblique; base rounded-truncate; margin sinuate-crenulate-dentate; midrib thick below, thin above, flexuous, curved to one side in its upper part; secondary nervation craspedodrome, pinnate subpalmate, arranged in five subopposite pairs above, and an opposite suprabasilar pair below that simulate lateral primaries, all diverging from the midrib at different angles but all curving more or less upward, each of the lowest pair with six branches on its under side, the branches mostly branched or forked toward their extremities, the main branches and their subdivisions terminating in the crenulations of the margin; basilar veinlets more or less branched and anastomosed, radiating laterally and downward from the midrib."
Remarks
From Hollick (1930) (p. 92-93)
"It is unfortunate that this leaf, in which the principl diagnostic characters are well preserved, should be distorted by wrinkling on one side, so that the complete normal outline is not indicated in the figure. It evidently, however, was broader than long and appears to have been obscurely trilobate. The inward-turned side of the leaf is clearly due to distortion and is not a specific character."
