"Plate 31, Fig 3"

"Leaf ovate-lanceolate, entire, 6 centimeters in length by 2.2 centimeters in maximum width, tapering above to a narrow apiculate apex, rounded below to a curved, wedge-shaped base; nervation quinquepalmate from the base, the inner pair of lateral primaries acrodrome, the outer pair gradually thinning out and merging, at about the middle of the leaf, into fine ascending secondary nerves that arise from the outer sides of the inner laterals."



From Hollick (1930) (p. 74)

"The species with which ours appears to be most nearly allied is Macclintockia cretacea Heer (1882; 1883) (p. 70, pl. 36, figs. 1, 2a; pl. 37 figs. 2 - 4. p. 27, pl. 55, fig. 14) from the Atane and Patoot beds of Greenland, to which a fragmentary specimen from the Dakota sandstone of Kansas is referred by Lesquereux (1892) (p. 197, pl. 59, fig. 4) but the identity of this specimen with that species is very doubtful, and it resembles ours more closely than it does the one to which it is referred.

Dawson (1885 [1886]) (p. 13, pl. 4, fig. 3) also refers a specimen from the Upper Cretaceous (Mill Creek series) of Canada to the same species; but his figure shows a leaf in which the inner pair of lateral primaries are suprabasilar, and it can hardly be referable even to the same genus."
