? Quercus sp.

Pl. 7, fig. 11

Oak-like cupule 10 mm in diameter covered densely by minute scales adhearing to the surface.

D i s c u s s i o n: This is the only evidence of possible oaks in the flora of Kučlín. The only minute specimen is an equivocal proof because similar cupules are developed also in Lithocarpus . And it may lead to the question whether some of the leaf impressions determined as Eotrigonobalanus could in fact represent Quercus . Without preservation of epidermal characters, it may be impossible to distinguish some species of these genera.

In any case, the affinity of the cupule to the Fagaceae is highly probable.
