A d d i t i o n a l m a t e r i a l. GBA2005/0004/0113.
D e s c r i p t i o n. Leaves petiolate; lamina elliptical to slightly obovate, l × w about 75–>100 × 29–55 mm, ratio l/w about 1.9–2.6, base convex, apex acute-acuminate; margin more or less distinctly simple serrate, number of teeth corresponding to secondaries, exceptionally only between secondaries (“ Fagus vel Alnus sp. ” sensu KovarEder et al. 2004: 61); teeth blunt, sinus rounded, proximal and distal sides mainly straight to slightly concave, distal side also sometimes slightly convex; midrib straight, slender; secondaries craspedodromous, slender, moderately dense, regularly spaced, originating at medium steep angles, near base commonly converging towards midvein, then running straight and sub-parallel into tooth apices; tertiaries forked percurrent, in strength almost equal to reticulate higher order veins.
R e m a r k s. Specimen GBA 2005/0004/0113 (Pl. 7, Fig. 18A) is by far the best preserved Fagus leaf from Parschlug. The lithology of this slab differs, however, from that of the majority of specimens which derive from hard marlstone-ironstone layers. In the collection of GBA, the orignal label of this specimen is missing. The presence of Dicotylophyllum sp. L, which has not been recorded elsewhere, on the same slab indicates Parschlug as the correct locality.
