The figured leaves of roburoid oaks are characterized by the regular round-lobate margin and are typical of Miocene and Pliocene floras (see e.g., Kvaček et al. 2008 ). Unless characterized by epidermal anatomy they can easily be mistaken for the previous species as happened in the flora of Vegora ( Kvaček et al. 2002 , pl. 14, fig. 1, pl. 15, figs 1, 4).
