Zelkova zelkovifolia (UNGER) BŮŽEK et KOTLABA

Pl. 7, Fig. 1–2

Leaves simple, shortly petiolate, elliptic to ovate, asymmetrical, 24 to 54 mm long and 14 to 34 mm wide, base widely cuneate to slightly cordate, apex shortly acute to acuminate, margin coarsely simple dentate to serrate, venation craspedodromous, midrib strong, moderate, straight, secondary veins distinct, alternate, straight or curved, at angles of 40–60°, tertiary veins straight, thin, often alternate percurrent, venation of the higher orders regular polygonal reticulate, areolation well developed, areoles 3- or 4-sided, veinlets not preserved.

Coarsely simple dentate-serrate leaves with craspedodromous secondary veins more widely spaced than in Ulmus are typical traits of Zelkova zelkovifolia , widely distributed in the Oligocene and Neogene of Europe (e.g., Kvaček et al. 2011).
