"Plate 74, Figures 2, 3"

"Leaves or leaflets inequilateral, asymmetric, 8 centimeters in length by 3.5 centimeters in width across the middle, tapering above to a blunt, acuminate, slightly curved apex, rounded below and broadly cuneate or truncate on one side of the base, sharply cuneate on the opposite side; margin entire; midrib curved above and below, in opposite directions; nervation simply pinnate, camptodrome; secondary nerves diverging from the midrib at obtuse angles on the rounded side of the leaf, especially in the lower part, and at acute angles on the opposite side, curving upward and anastomosing close to the margin."



From Hollick (1930) (p.98)

"These specimens probably represent leaflets of a compound leaf such as are common in a number of genera in the Leguminosae. They are similar in general appearance to the European Tertiary species Cassia phaseolites Unger (1850) (p. 188 [58], pl. 66, figs. 1 - 9) and they evidently belong either in that genus or in one closely related."
