1852 Acer integrilobum C.O. WEBER , p. 196, pl. 22, fig. 5a–5b (non fig. 5c).

Leaf trilobate, ca. 20 mm long and fragmentary in width, lobes entire-margined.

D i s c u s s i o n. Such maple leaves with almost entire margin are rare in the Oligocene leaf assemblages of the České středohoří Mountains ( Walther 1972, Kvaček and Walther 1998). They occur commonly in the Oligocene localities Rott and Seifhennersdorf and differ from entire-margined trilobed forms of A. integerrimum (VIVIANI) MASSOLONGO in acuminate apices of lobes ( Walther 1972).
