Description

From Hollick (1930) (p. 96)

"Plate 63, Figure 3; Plate 64, Figures 1, 2"

"Leaves palmately trilobed with a broad, truncate, peltate (?) base, about 14 centimeters in length by about 18 centimeters in width between the extremities of the lateral lobes; middle lobe large, broadly wedge shaped; lateral lobes relatively small, triangular, tapering to the blunt apices; margin triangular-dentate; teeth blunt; nervation craspedodrome; secondary nerves opposite below, becoming alternate above, sub-parallel, leaving the midrib at approximately equal angles of about 45°, curving slightly upward; lateral primaries suprabasilar, leaving the midrib at obtuse angles of divergence, widely spreading, branched on the under sides and on the upper sides toward the extremities; basilar veinlets conspicuous, at right angles to the sides of the midrib."

 

Remarks

From Hollick (1930) (p. 96)

"The platanoid aspect of these leaves might cause them to be referred to the genus Platanus were it not for the apparent peltate character of the bases. It is unfortunate that in no specimen is a perfect base preserved; but certain peltate characters are obvious, and
others are strongly indicated, so that this feature may be assumed to be present in normal leaves."
