Quercus roburoides GAUDIN

Pl. 8, Fig. 1–2

Leaves long petiolate, obovate, pinately lobed, 52 to 130 mm long and 25 to 65 mm wide, base rounded or cuneate to decurrent, apex slightly attenuate to obtuse, margin entire in basal part, coarsely simply dentate in the apical part, teeth obtuse to rounded, sinuses rounded, slightly opened to widely opened, venation simple craspedodromous, midrib strong, moderate, secondary veins thinner, alternate, straight to curved, tertiary veins alternate precurrent, sinuous to straight, venation of the higher orders regular polygonal reticulate, areolation well developed, 3- to 4-sided.

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).
