Pl. 6, Fig. 7–8
Leaves elliptic to rarely ovate, petiolate, 25 to 58 mm long 7 and 15 mm wide, base cuneate to widely cuneate, apex obtuse to acute, margin coarsely serrate, teeth, close, blunt, rarely acute, often regular, sinus angular, venation semicraspedodromous, midrib strong, straight, moderate, secondary veins steep, thinner, straight, looping by the margin, alternate, rarely forked, tertiary veins alternate to opposite percurrent, straight to sinuous, venation of the higher orders regular polygonal reticulate, areolation well developed, areoles 3- or 4-sided, veinlets poorly preserved, probably lacking.
The leaves characterized by moderately steep secondary semicraspedodromous venation are similar to the evergreen foliage of Pyracantha , a native shrub from southern Europe to central China. It also resembles the fossil species P. kraeuselii WALTHER ( Mai and Walther 1978) known from the Oligocene of Saxony.
