Two leaf fragments showing coarsely dentate margins and which prove the occurrence of this fossil species at Knížecí.
D i s c u s s i o n. In general both fragments match a much more diversified record from Kundratice and Bechlejovice ( Kvaček and Walther 1998, 2004). They differ from the simple dentate elm foliage, e.g. Ulmus fischeri HEER , in having fewer secondary veins, although in some critical cases the differentiation might be arbitrary.
