M a t e r i a l. 2 specimens, Líšeň-Neklež ( MB104 ,

MB105b).

D e s c r i p t i o n. Leaflet narrow elliptic to slightly ovate, 38 mm long, 8 mm wide, apex acute, base asymmetric, cuneate, shortly petiolulate, margin in the lower part entire, higher up simply widely serrate, teeth acute, sinus angular, venation camptodromous to semicraspedodromous, midrib strong, moderately narrowed, straight to slightly curved, secondary veins distinctly thinner, numerous and dense, mostly straight, alternate, departing from midvein at angles of 50° to 80°, forming loops near margin, intersecondaries parallel with secondaries, thinner, tertiary veins straight to sinuous, higher order venation poorly preserved.

R e m a r k s. This fossil-species is widely distributed in warmer floras of the Oligocene and Miocene of Europe (e.g., Knobloch and Kvaček 1976, Kvaček and Walther 1995, Kovar-Eder et al. 2004, Walther and Kvaček 2007, Kvaček et al. 2011). Its affinities are clearly with the tribe Engelhardieae W.E.MANNING , close to the living Oreomunnea OERST. Due to its intermediate taxonomical position, it has been variously assigned to Engelhardia s. l., Palaeocarya SAPORTA or Oreoroa DILCHER et MANCHESTER ( Knobloch and Kvaček 1976, Jähnichen et al. 1977, 1984).
