Description

From Hollick (1930) (p. 78)

"Plate 42, Figure 5"

"Leaf of unknown shape, inequilateral (?), about 4.5 centimeters in length by about 7 centimeters in width, with a broad, entire, wavy, truncate base; midrib curved, weak, with two subopposite pairs of widely separated, sharply ascending, inward-curving secondary nerves; nervation palmate from the base; lateral primaries equal in rank with the midrib, two on one side, three on the other, spreading, branched, the lower branches of the lower lateral primaries extending along and subparallel to the basal margin."

 

Remarks

From Hollick (1930) (p. 78)

"This leaf, as indicated by its spreading lateral primaries, was apparently trilobate, and what are apparently the lower branches of the lower pair of lateral primaries may represent a pair of basilar lateral veinlets. From the general characters of the imperfectly preserved nervation the leaf is suggestive of either Menispermites or Hedera and might, with equal propriety, be referred to either genus. Only a perfect specimen could satisfactorily determine the probable generic affiliation. The shape of the leaf was apparently somewhat comparable with that of Hedera cretacea Lesquereux (1892) (p. 127, pl. 18, fig. 1) but the characters of the nervation are different and are more like those of Menispermites."
