Platanus leucophylla (UNGER) KNOBLOCH

Pl. 4, Fig. 10–14

Leaves long petiolate, palmately sub 3-lobed, rarely non-lobed, lamina broadly ovate, 40 to 95 mm long and 20 to 125 mm wide, medial lobe triangular to widely triangular, lateral lobes absent or triangular, apices acute, base cuneate to widely cuneate, petiole up to 32 mm long and 3 mm wide; margin irregularly coarsely simple serrate, at leaf base often entire, teeth obtuse to acute, venation basal actinodromous, 3 to 5 primary veins, straight, moderately thick, secondary veins thinner, alternate, straight, originating at angles of 30–40°, tertiary veins alternate to opposite percurrent, straight to sinuous, venation of the higher orders regular polygonal reticulate, areolation well developed, 3- to 4-sided, veinlets not preserved.

Both palmately lobed and simple leaves are present. This fossil species is widely distributed in the European late Miocene sites, e.g., Knobloch (1969) as Platanus platanifolia (ETTINGSHAUSEN) KNOBLOCH (Fischer and Butzman 2000, Kvaček et al. 2002, Kovar-Eder et al. 2006).
