"Plate 38, Figure 1"

"Leaf obovate-oblong, asymmetrical, entire, 8 centimeters in length by 5.9 centimeters in maximum width; apex blunt; base broadly wedge-shaped; nervation pinnate, consisting of a midrib with five alternate secondary nerves on each side that leave the midrib at angles of about 45° and curve upward along the margin."



From Hollick (1930) (p. 72-73)

"This specimen represents a leaf that is difficult to assign generically. It might be regarded as belonging to Ficus, or Juglans, or Magnolia, or to some other genus with leaves that have simple, curved, pinnate secondary nervation and entire margins; hence the reference to the genus Ficus is indicated as questionable. It is of the same general type as Ficus asiminaefolia Lesquereux (1884 [1885]; 1893) (p. 76; p. 14, pl. A, fig. 5) from the Tertiary of California, in connection with which Lesquereux remarks: "This leaf has somewhat the appearance of a Juglans and also of a Magnolia"; and it may be compared with Ficus mudgei Lesquereux (1892) (p. 83, pl. 12, fig. 4) from the Dakota sandstone of Kansas.

Leaves of similar general appearance, from the Magothy formation of Maryland, are referred by Berry (1916) (p. 824, pl. 68, figs. 2 - 4) to Magnolia obtusata Heer (1882) (p. 90, pl. 15, fig. 12; pl. 21, fig. 3) although these leaves, to judge from the figures, almost certainly represent a species distinct from M. obtusata."
