2007 Carpinus roscheri KVAČEK et WALTHER ; Walther and Kvaček, p. 105, pl. 10, fig. 1–5, text-fig. c–e.

Leaves broadly ovate, 45–65 mm long, 31–39 wide, base rounded to subcordate, margin coarsely double serrate, midrib almost straight, thick, secondary veins regularly parallel, at angles of 50°, in leaf base up to 70°, opposite or slightly alternate, in 10 pairs ca. 6 mm apart.

D i s c u s s i o n. Foliage similar to the newly described fossil species C. roscheri from Seifhennersdorf ( Walther and Kvaček 2007) was recovered by Knobloch (1961, as Betula brongniartii ) also at Knížecí. As at Seifhennersdorf this type of foliage is accompanied by involucres, assigned to Carpinus cordataeformis and differing from the C. orientalis – type in shallow lobed margins.
