From Hollick (1930) (p. 51)

"This leaf is referred with some hesitation to this species for the reason that the specimens upon which the species was originally based by Lesquereux are very small as compared with ours, although in other characters they agree closely. Knowlton (1893) (p. 47, pl. 1, figs. 1 - 4) however, refers specimens as large as ours, from the so-called "Laramie" formation (Eagle sandstone) of Montana, to the species, and in connection with these leaves specific identity with ours can hardly be questioned."
