Leaves oblong to narrow ovate, incomplete in length, 23–30 mm wide, on margin simple serrate, teeth blunt, almost glandular, quite widely spaced, secondary veins eucamptodromous-semicraspedodromous, at angles of 30– 35°, partly looping, tertiary veins oblique or perpendicular, prominent, higher-order venation distinct. D i s c u s s i o n. Knobloch (1961) compared some alder leaf impresions from Knížecí with Alnus kefersteinii , which is based on generative organs, and erroneously compared some leaf impressions with the Juglandaceae (as? Pterocarya aff. denticulata ( GÖPPERT ) SCHLECHTENDAL ). Similar foliage occurs e.g. at Kundratice, from where the epidermal structure has also been obtained ( Kvaček and Walther 1998 ).
