D e s c r i p t i o n. The two studied leaves are shortly petiolate, with an ovate to elongate blade; one is oblique at the base, the other slightly asymmetrical, margin coarsely crenate-serrate. Three basal veins arise at acute angles from the lamina base. Details of venation are poorly visible.

D i s c u s s i o n. The material matches other Celtis foliage recovered elsewhere in a few of the volcanic sites of North Bohemia and Saxony ( Radoň et al. 2006, Walther and Kvaček 2007). We follow the treatment proposed by Walther and Kvaček (2007) and leave separately other fossil species known from the Neogene, such as Celtis trachytica ETTINGSH.
