From Hollick (1930) (p. 49)

"Plate 12; Figures 5-7"

"Leaves suborbicular or reniform, about 7 centimeters in length by 8 centimeters in maximum width, abruptly and narrowly wedge-shaped at the base; margin entire; nervation flabellate, divergent, fine, dichotomously forked."



From Hollick (1930) (p. 49)

"It is with some hesitation that I give these leaves a distinct specific name, especially as the specimens are imperfect, and all their characters can not be determined. They may represent merely a large, rotund form of Ginkgo laramiensia Ward (see pl. 12, figs. 3, 4), but their large size as well as distinctive shape appear to differentiate the species more or less satisfactorily."
