"Plate 83, Figure 2"

"Leaf symmetrically trilobate, entire, rounded-cuneate from about the middle downward; lobes rounded-triangular, obtusely apiculate, the apical lobe relatively long and narrow, the lateral lobes short, broad unilobodentate on the outer sides; midrib straight, thickened from the junction of the lateral primaries downward; secondary nervation sparse, fine, camptodrome; lateral primaries craspedodrome, suprabasilar, subtending acute angles with the midrib, each with a prominent branch extending at an acute angle of divergence from the lower part to the apex of the adjacent lobodentitlion."



From Hollick (1930) (p. 110)

"There can be but little doubt that this leaf represents the same generic type Sassafras (Araliopsia) platanoides Lesquereux (1883) (p. 58, pl. 7, fig. 1) from the Dakota sandstone of Kansas. The salient characters in each are practically identical; but our leaf is smaller, the lobes are less rounded in outline, and the angles of divergence of the lateral primaries and their branches are more acute.

Whether these and other more or less similar leaves should be regarded as related to Sassafras, or Platanus, or Cissites, or Aralia need not be here considered; but anyone who may be interested in this question may find it discussed by Berry (1911; 1916) (p. 413; p. 878) in connection with the flora of the Raritan formation of Maryland."
