Description
From Hollick (1930) (p. 111-112)
"Leaf small, 4 centimeters in length by 3.5 centimeters in width across the base, triangular cordate, subtrilobate; margin undulate; nervation palmate from the base, craspedo-camptodrome; midrib supporting two pairs of subopposite, widely separated, upward- curved secondary nerves that extend to and disappear in the marginal undulations; lateral primaries two on each side of the midrib, the inner pair radiating at an angle of about 45°, the outer or lower pair approximatey horizontal, forked toward their extremities, the ultimate branches extending to a"nd disappearing along the border of the margin; basilar veinlets obscurely defined."
Remarks
From Hollick (1930) (p. 111-112)
"This leaf is very similar in appearance to certain of the common leaf forms of the living Hedera helix Linnaeus, and also to the Tertiary species H. strozzii Gaudin (1858) (p. 37, pl. 12, figs. 1 - 3) and it is interesting to find an ancestral Cretaceous species in which the leaf form is so closely similar in its appearance to recent and living forms of this type."
