Leaflets mostly ovate, small-sized, 19–54 mm long, 22– 19 mm wide, crenulate to finely denticulate on margin, sub-sessile, venation dense, semi-craspedodromous. Knobloch (1961) characterized the material very briefly: (translated from German): “Leaflets oval, simple dentate, at base slightly asymmetrical, teeth apically orientated, secondary veins steep and entering the marginal teeth.”

D i s c u s s i o n. Knobloch (1961) refered to a monograph of fossil roses, predicted to have been accomplished by the Czech expert Dr. Ivan Klášterský but which was never finished, and therefore treated the remains of roses very superficially. Detached leaflets of similar type and crenulate margin as well as complete compound leaves had been since known from other localities in the České středohoří Mountains, e.g. Kundratice ( Kvaček and Walther 1998), Roudníky ( Kvaček et al. 2014) and in particular Bechlejovice ( Kvaček and Walther 2004).
