Leaves pinnately compound, leaflets incompletely preserved, sessile, subopposite, lamina narrow oblong, straight to slightly falcate, 40 and more mm long, and 10–20 mm wide, base asymmetrical, cuneate to rounded, apex acute, margin basally entire, higher up widely minutely serrate, tooth tips bluntly acute, partly abmedially oblique, sinus shallow, acute to blunt; venation semicraspedodromous, midrib slightly curved to straight, thick, secondaries delicate, dense, under wide angles, running and looping very near the margin and sending veinlets near the sinus into the tooth, intersecondaries dense, parallel with the secondaries; venation details poorly preserved

D i s c u s s i o n: Leaflets of Engelhardia orsbergensis occur quite rarely at Kučlín while they are common in the Oligocene of, e.g., Suletice-Berand ( Kvaček and Walther 1995), Holý Kluk hill at Proboštov ( Radoň et al. 2006) and Haselbach ( Jähnichen et al. 1977, Walther in Mai and Walther 1978). As in other sites, also at Kučlín they are accompanied by fruits of E. macroptera (see below). Engelhardia belongs certainly to thermophilous and mesophytic elements.
