"Plate 79, Figures 5-6"

"Leaf elliptical, 4.25 centimeters in length by 2.5 centimeters in width at about the middle; margin entire; apex rounded, blunt; base rounded-cuneate; nervation palmate, consisting of a straight midrib, an inner pair of simple acrodrome primaries, with branches above on the outer sides, and an outer pair, simple below, becoming looped and camptodrome above, where they join with and merge into the secondary and tertiary nervation, forming a marginal network of rounded, polygonal areolae."



From Hollick (1930) (p. 102-103)

"This leaf bears a striking resemblance to Zizyphus pinsonensis Berry (1916) (p. 280, pl. 71, fig. 7) from the Lagrange formation of western Tennessee, and except that Berry's species has a more acute, wedge-shaped base the two would be difficult to separate. The apex in each specimen is missing, unfortunately, but the indications are that each was rounded and blunt."
