Pl. 9, Fig. 4–5; Pl. 10, Fig. 5–7
Leaves petiolate, narrow elliptic to ovate, 40 to 82 mm long and 9 to 11 mm wide, apex attenuate, base widely cuneate to rounded with incomplete petiole up to 4 mm long, margin entire in the basal part, regularly simply serrate, teeth acute to rounded, glandular, sinus angular, venation semicraspedodromous to eucamptodromous, midrib strong, straight, moderate, secondaries subopposite to alternate, distinctly thinner, numerous, curved, originating at acute angles, tertiary veins alternate to opposite percurrent, straight to convex or sinuous, marginal veinlets innervating teeth apices, venation of the higher orders regular polygonal reticulate, areolation well developed, 3- to 4-sided.
These narrow leaves undoubtedly belong to a willow. Similar morphotypes are usually assigned to Salix lavateri A. BRAUN typified by populations from the middle Miocene of the Oehningen area (e.g., Hantke 1954).The exact distinguishing traits have not been clarified so far, even in cases of anatomically preserved material (e.g., Kvaček et al. 2008).
