Description
From Hollick (1930) (p. 93-94)
"Plate 68"
"Leaf large, 19 centimeters in length by 19 centimeters in width across the middle, coriaceous, ovate-orbicular, obscurely trilobate, with a wavy margin and an auriculate, alate, or possibly peltate base; midrib abruptly thickened between the basal secondaries and the pair above, and again below the basal secondaries; nervation coarse, pinnate subpalmate; secondary nerves opposite and subopposite below, alternate above, diverging from the midrib at approximately equal angles of about 45°, flexuous, mostly forked toward the extremities, craspedodrome, lowest pair suprabasilar, simulating lateral primaries, irregularly branched on the under sides; basilar nervilles radiating laterally and downward from the midrib at a distance of 5 millimeters below the basal secondaries."
Remarks
From Hollick (1930) (p. 93-94)
"This is apparently an obscurely trilobate, peltate leaf, the middle basilar extension of which has disintegrated, exposing the upper part of the petiole, which normally would be hidden from view; or the specimen may represent the back of the leaf, with the petiole pressed against the underlying lamina. The texture was evidently coarse or coriaceous and the nervation strong, as may be seen by the almost perfect preservation of the tertiary nervation throughout."
