The leaf material is morphologically similar to Alnus menzelii and also Alnus rotundata GOEPPERT ( Raniecka-Bobrowska 1954 , Zastawniak and Walther 1998 ), which are commonly known from the European Oligocene and Neogene. An affinity to Alnus ducalis ( GAUDIN ) KNOBLOCH is also possible, however a typically deeply emarginate apex is not preserved ( Knobloch 1969 , Kvaček et al. 2002 ). M a t e r i a l. Leaf fragment (Monte Tondo MSF1524, MSF1525).
